00:05So before we kick off with our discussion on any c compliant cable glands,

00:09I would just like to welcome our lovely panel of experts as we have some new faces in this

00:15session. So we've got Henry Turner, uh business

00:18development Manager from Hawk. If you wanna give us a little wave,

00:21Henry, uh we've got me Mar Cole Certifications manager at Cole

00:28Canada. We've got Matt Oden, our senior product

00:33specialist from Hawk who you'll probably know from a few of our previous sessions.

00:37We also, oh, sorry, Matt cut you off a little bit there.

00:42Um And we also have Mike Sinner, um who will be monitoring the chats.

00:47Um So don't be afraid to ask him some questions as well in the chat and he is our fittings

00:52product manager from Klock.

00:54So let's kick off the questions.

00:57So the first question we have is about um changes in the markings uh on our products.

01:03So, Henry, if you want to talk a little bit about that to kick off with Sure,

01:09I'll be glad to. Um and we've had as of last year,

01:13we, we did have a change in some of our specifically the um class one div two rated

01:20cable glands.

01:21Uh It's really for a matter of clarification, more of a marking clarifications.

01:26Um It's not a certification that we lost.

01:29Um, but it is something that is required clarification from the certifying bodies.

01:36So, within the standards itself, in a class one div two area,

01:41you typically your, your option is either to have a compound slash barrier gland or um some

01:48applications will also allow um if you have just like a sheet steel enclosure of some type

01:54with hermetically sealed devices or no um no arching or sparking devices,

01:59then you can use a noncompound barrier type gland in those applications.

02:06But because we were marking the cable glands as div two um which is was

02:12allowed by the standards. Um They were unfortunately being misapplied in

02:18the field and we were having um class one div two marked non barrier glands

02:24were actually being installed into explosion proof um with arching sparking type devices

02:31inside the enclosure.

02:33So after various inspectors and different things like that got involved.

02:38Um and even went to the certifying bodies advising them of some of these issues they were

02:44finding in the field.

02:45Then um the likes of, you know, UL CS A et cetera um reviewed that and

02:52basically came back in just to eliminate any potential confusion.

02:57Um and just to try to, to mitigate any type of issues like that to ensure the products are

03:03being applied in the field correctly.

03:06Then, um they basically went to all of the cable gla manufacturers and anybody who had a

03:12class one div two marked noncompound Gland, they requested that we remove those markings.

03:20So that's probably the biggest change that we've had on our uh markings as a uh as it

03:26relates to the class one D two cable glands.

03:29Um just uh and it's really just a more of a clarification on the markings,

03:35but it is something going forward that, that everybody will see across the board with any of

03:39the cable gland manufacturers. So today, the only cable glands we can mark

03:44class one div two are going to have the compound chamber um built into the product

03:49itself. You can still use the other glands in a class

03:53one D two area, but they must be applied in accordance to the standards.

03:57So that's, that's the basic update. Perfect. Thank you and Marty,

04:03is there anything you would like to add to that?

04:06Yeah. And to what Henry was saying,

04:08certification agencies haven't quite caught up with all the manufacturers to have them update

04:15their files and that's a lengthy process once they make a change.

04:19So you might find some that are marked that way, but they'll be losing it in the,

04:24when their file review is done. So that's important to understand if they're

04:27telling you we have it and somebody else does it.

04:30That's not correct.

04:31Everybody is facing this. Perfect.

04:38Thank you. Thank you for those points. Matt.

04:40Is there anything that you'd like to add there?

04:42No, I think Martin and we have pretty, pretty much covered that in the correct way.

04:46I think uh I don't think there's anything else to add.

04:49Perfect. Thank you.

04:50Great answers there.

04:51So, the next question uh that we had within the show was what are the main differences between

04:58en slash IEC compliant glands and NC glands? So, Marty,

05:02if you want to kick off that one, our, our world is a little bit different.

05:08In North America, we certify cables and in the rest of the world,

05:15they just have to comply with the standards for those cables.

05:19They're not, they don't go through a certification process.

05:22So an IEC type cable, Gland would not be certified with a cable installed,

05:29it would be certified with a test device, mandril to see if it complies with the

05:34explosion proof properties in North America. Since we certify cables,

05:39we also certify the glands to go with specific cables.

05:42So there's a match and the gland will tell you which cables are suitable to be used with that

05:48cable. Gland if you have a different cable, it may not

05:52be suitable with that uh because it isn't certified for that purpose.

05:56So that's a huge difference between how North America approved,

06:00approves cables with cable glands and they, that that process is independent in the rest of

06:06the world. Does that make sense?

06:12I think it's good to add there that, that we as a, as a manufacturer have to actively go out

06:18and, and, and ask for this cert certification to be,

06:22to go along with the cable types that people are using.

06:24Um, it's not just a, a mandatory thing. We have to actively go out.

06:28And if, if we see a requirement, we go to the, to the certification bodies and ask for that to

06:33be added to our certificate.

06:34So it isn't like Marty said, it's not an automatic thing.

06:37It's something that we have to go out and obviously seek,

06:39right? And we, we keep up to date with what cables are

06:42being used by industry and certify them accordingly.

06:46Uh Certainly for North America that, that, that's we must do that for people to use it.

06:51Um It's, it's fairly static within IEC uh as to what cables people want to use and our

06:58ga our glands accommodate them and we investigate that internally to make sure that

07:03we fit them right?

07:05And take care of other issues such as cold flow and things like that.

07:08It was discussed in previous things. So perfect and just to touch on that kind

07:15of a, a little bit more and we'll, we'll talk, we'll touch on the kind of benefits of the,

07:19the nuclear compound part that we have now.

07:21But for Hawke's new range of cable glands, Marty, could you,

07:24could you talk us a little bit through the the certification process that they've been through

07:27in general for an ec specifically the compound part as well.

07:32Uh So we, we have a non metallic potting chamber in our new Cable Gland,

07:38which is a first for North America that didn't exist here before.

07:42So it allows you to better inspect the gland.

07:44Um There's a lengthy process to get the materials that the sort of agencies will agree

07:51to, to make sure it works with, maintains a exposure proof properties of the,

07:57the cable Gland.

07:58Uh It, it's not a quick fix fix in North America because they have lots of different

08:04rules for materials and everything else.

08:06So it isn't something that happens overnight and we spend a lot of time getting that uh the

08:12new compound, maybe Matt Connett talk about how quickly that sets and the advantages of that

08:18over the competition.

08:19Yeah, of course, just touching on a point obviously, with the previous question,

08:23obviously, we, yeah, we searched extensively to find a suitable material that will give us

08:29resistance to some of the tests that we have to go through to meet that the,

08:33the, the North American standards like the chemical test that the um hydrostatic test,

08:39the the uh explosion tests and to ensure that the compound matched the silicon that we

08:45selected and that it passed all of these, these extreme tests that,

08:51that you have to go through to meet that UL or that, that North American standard.

08:54Obviously, was, was something that we had to search through numerous different processes and

09:01research projects.

09:03Um, to get to that, to get to that point, the uul test for plastics is

09:09actually a brutal test.

09:11It's a 13 chemical soup with a lot of really terrible chemicals that nobody should be

09:16exposed to. But it, they put it through a torture test and

09:21we find with a lot of international products, they may be perfectly good products,

09:25but they will not pass the plastics tests that UL puts forth.

09:29So that's an important point to note that it's, it's an investigation to find the correct

09:34materials to meet all those test requirements.

09:37And I suppose that goes some way to explaining why this is the first non metallic compound

09:42part as well if it has to go through. Yeah.

09:45Um, I mean, we've kind of touched on a few of the benefits of the compound part.

09:48Marty's touched on them, but Matt, is there anything you'd like to expand on there?

09:51Yeah, I think that's a perfect segue into kind of what was there before and what's there now.

09:56So obviously, previously, we would have had, I'll just bring up a,

09:59a quick slide on the screen actually, just to show the difference of previous,

10:02we would have had something like the, the brass metallic pot that you see on the um

10:09on the right hand side of the screen. So that was obviously the,

10:12that would give you a flame path. That's obviously a traditional way that North

10:16America would have, would have would see cable glands with compound chambers,

10:21but we obviously manufactured in the UK. And for being a G A global supplier of cable

10:27glands, obviously saw the benefits of being able to offer something with inspect ability

10:31and our previous design before we kind of moved on to this generation of cable glands,

10:36which we switched over to in um July 2019, we had a removable compound chamber that was

10:42made of a, a santarem plastic material.

10:45Now you filled that with a, with a putty and you could remove that once it was hard and you

10:49could see whether it was filled correctly and it had,

10:51it had filled all the voids and the putty had moved around all of the cores.

10:55Now, obviously with that design and obviously, the movement that we are definitely behind

11:02the curve on which we're trying to obviously catch up with.

11:05Now is obviously the introduction of a of a uh a liquid pore seal.

11:09Now with a liquid poor seal, it acts slightly differently when it goes harder and the the

11:14adhesion of between the, the, the actual epoxy resin that we use and the,

11:18the, the the plastics that we use in these compound chambers,

11:21it wasn't possible in the old design. So we had to develop something new and removing

11:28re removing that compound chamber off some off of the epoxy liquid but it was not really a

11:33viable option. So that's when we started to look at uh at see

11:36through uh materials. And obviously, the, the clear silicon compound

11:41pot is obviously where we've, where we pushed and obviously pushed for certification to get

11:45over the line. And obviously the, the, the inspect ability

11:49aspect of it, you can see as you're pouring and you can ensure that that is that has been

11:54installed correctly First time, every time, um as the material flows around all of the cores,

12:00it fills up. It's, it's night and day between the,

12:03the, the black compound that we supply and the clear resin.

12:07So you can easily see that it's been filled properly.

12:13Perfect. Thank you.

12:14And just before we move on to maybe some more of uh details about the uh types of compounds

12:19that we offer. We have a question in the chat from uh Daniel

12:22about the, the chemicals that are in the soup that are part of the testing Marty.

12:26Do you have any anything you could expand on there?

12:29Oh, I oh, I have to look them all up. There's, there's benzene toe.

12:34Um I don't have a list without the list is impossible.

12:40I'll find the list and give it back to you in a minute.

12:43We can send that over to you, Daniel after this if you're interested.

12:48So, Matt, did you have something you wanted to expand on there or are you happy for Henry?

12:51To talk a little bit more about the types of compounds we offer.

12:53No far away Henry. It's, um, I've got a, a video as well if you

12:57want me to play that in the background of obviously the process,

12:59but I'll, I'll bring that up as, and when we start talking about it.

13:02Sure. Ok. Yeah. So the different types of resins that we have,

13:06uh, we still offer the standard, um, two part compound that you can mix up.

13:11Um The, the biggest advantage of that though. Now, you know,

13:15that used to have some, some longer cure times associated with it.

13:19Um But now you're more popular sizes um up to say like our size CC two glands.

13:26Um We now offer that with a uh a quick curing.

13:30Um So, but anything larger than that, it's gonna go into your standard and that's just

13:36because of the amount of work time that's gonna take to um to,

13:39to fill the voids and everything else and provide your seals around the conductors.

13:44Um But you definitely gonna have the, the quick seal or the quick curing on the smaller sizes,

13:49which is by far, uh you're gonna have more of those on a job than you are the larger ones.

13:54And then the other option, um which Matt has alluded to is the,

13:59the injectable resin uh makes it very simple to, to do your installation.

14:04And um it, the cure times on that is gonna be you know,

14:07roughly and there, there's a temperature chart associated with that but what I've seen,

14:13um, here in the Gulf coast, um, and even on east and west coast during the summer months,

14:19um, we've, we've seen some of that, uh, get to, uh, what they call a shore hardness,

14:24um, within 15 to 20 minutes.

14:27Um, but you obviously wanna make sure that, that you're,

14:30um, you know, looking at the temperature gauges and making sure that it's properly cured before

14:34you start handling it afterwards. But um there's pros and cons to both um with

14:41the, the QSP version, which is your co your two part compound.

14:44If you're doing having to do horizontal installations, then you still have the ability

14:49to do that. And you also have the, the faster curing times

14:53with the um with the injectables. Then, um you're,

14:57you're gonna have that, that's gonna be a probably about a 30 minute cure time.

15:02Um irregardless of the size.

15:04Um But that's gonna be predominantly for, you know, you will have to make sure that you allow

15:09that to cure in a vertical position.

15:12Um But that will uh you're still gonna get your faster cure times.

15:16And the biggest benefit to all this is that you're still,

15:19they use, use the exact same compound pot, the clear pot.

15:24So with both resins, you're going to get your full inspect ability,

15:29um you also get your faster curing times.

15:33Um But you'll be able to manipulate it. As you can see with the video that's going on

15:37right now, the the silicone pot is flexible.

15:41So if you see any voids in the, the resin itself, you can simply just manipulate it and

15:46you can actually watch the bubbles um go up to the top so that you don't have any,

15:52any bubbles or voids in the actual uh termination.

15:56And it's the same with the two part compound, You mix that up,

15:59you pack it around and when you slide the pot over, then you can manipulate it and you can

16:04continue to, to pack more compound in because that's really the,

16:08the biggest question I get as someone who goes out and does a lot of the gland termination

16:13trainings from the guys out in the field, um, you know,

16:17with the compound, how do you know you have enough?

16:19How do you know you don't have any voids, um, whether it's the injectable or the other?

16:25And to be quite honest with the brass pots, you don't, you don't really have that with the

16:29metallic pot, but with the, the clear pots, you can clearly see that you have,

16:34um, you don't have the voids and you, you've got it cleared and which makes it easier for

16:39the installer.

16:41So they, they know they're doing their actual termination correctly and ultimately makes it

16:46easier for the inspectors and the, uh, the clients to make sure that they're getting a,

16:51a proper seal, which is obviously the most important thing when you're looking at

16:55explosion protection.

16:56So the one thing to touch on there is just the the application of the of certainly the express

17:03resin and using the the syringe with the with the nozzle that premixes everything for you.

17:09So as you push the two, the two parts of the syringe into one nozzle,

17:13it mixes, everything comes out the out of the the tip of the nozzle as a 1 to 1 mix,

17:18that mix is obviously in a perfect ratio to ensure that,

17:21you know, everything happens as it should do.

17:24Um And then obviously, as Henry said, you know, you've got a pure time of,

17:28of a total of of 30 minutes in normal ambient temperature, but it actually gels in around 8

17:33to 10 minutes. So after 8 to 10 minutes, you can then turn it

17:36horizontal. So you don't have to be vertical anymore.

17:39Um Obviously, the ability of that is then you can continue to work.

17:42You could rack these up 1020 at a time. You can go along with,

17:46we we also sell larger syringes um up to 250 mils.

17:51Um So you could use multiple or you or or fill multiple glands with one syringe.

17:56And then as you get to the other end, the first one's cured and you can continue with your

17:59installation rather than previously having to wait certainly with the compound where you

18:03might have to wait 1 to 2 hours with the QSP or potentially 24 hours in some conditions with

18:09the, with the longer queue input it.

18:11So it is a much faster process and the application is just much faster than,

18:15you know, previously we've had and what we believe any of our competitors as well.

18:23Perfect. Thank you.

18:24Um We do, we have that question in the chat uh from Bob Johnson.

18:29Um Thank you for your question is the IC G 653 and 753 basically.

18:35Now and now one and the same Gland designed for braided cable.

18:40It is, it is, it, it's, it's apart apart from the marking,

18:44apart from the certification, the actual design of the product is the same.

18:48Um And it's o only because we need to have that UX marking that North American standard on

18:55there. Um And we have the IC G 653 for the, for the

18:58rest of the world. Um How do you want to touch on that?

19:01Obviously, it is now the one and the same with regards to the 753 and the 755 that we used to

19:07have. Yeah, the um, you are correct that they are

19:12virtually the same. It's just gonna be the markings on the glands

19:15are gonna be a little bit different.

19:17Um The, the actual certifications are gonna be identical, the 753 series is going to maintain

19:24the, the UL certifications as a class one div one cable Glan the,

19:30the IC GS.

19:32Um and I know this kind of leads into one of the other questions that we had.

19:35But the IC G is in effect with, we can, now we offer a conversion kit that the,

19:41the 501453 Universal, you can convert into an IC G 653.

19:46So in those cases, um you could actually take a 501 and then convert it to an IC G that could

19:53also be used in the same areas as a 753.

19:57We kept the gland separated like that because from a specification standpoint and we still

20:02have a lot of customers that utilize the 753 you know,

20:06throughout their systems, whereas the, the IC G will probably predominantly end up at some

20:12point. Um We will have that offered as part of a

20:15conversion kit um which I know Matt that was one of the questions you were going to address.

20:22Mhm. Would you like to expand on the conversion kit

20:25at all? Yeah, so, so when we were obviously looking at

20:29the initial in the initial of the iron phase of of this new range,

20:33we obviously wanted to offer versatility, inspect ability,

20:36all all of the things that we, you know, we design all the parameters that we design around

20:41at Hawk.

20:42And one of them things was obviously looking at our, you know,

20:46flagship Gland really in, in the, as a global Gland is the 501453 universal.

20:51That's a diaphragm seal. It's there designed to limit the amount of

20:54potential coal flow and the pressure that's applied to an inner,

20:57inner sheet of a cable and essentially reduce that.

21:02Um And that's like I say, one of our most, most specked cable guns that we,

21:07that we manufacture coupled with that. Obviously, we see in the market,

21:11the changes in standards with regards to um effective fulfilled cables and the 3 m rule,

21:17certainly within the rest of the IEC world.

21:20Um And also if it, obviously, if it's under 3 m, we have to put a barrier gland on there.

21:25And if the cable doesn't meet a, an effectively filled test where gas could potentially migrate

21:30through the through the cable, then we have to fit a barrier gland now because the onus is on

21:36the installer. And sometimes you know that the first point in

21:40which they're seeing the equipment that they're supposed to be working with is on is actually

21:43on site when they're actually physically putting it together.

21:45Now, if it comes to that point and they realize that actually a Barry Gland should be fitted,

21:50then what we don't want to do is have them having to,

21:53to either fit the wrong cable gland or have to wait 6 to 10 weeks for,

21:58for a new cable gun to potentially turn up. So they can actually do the job properly.

22:02So, what we did was we tried to obviously have the most uh as many common parts within the

22:07Grand itself, I'll just bring up a uh another.

22:14So we wanted to have as many common parts as possible.

22:16And as you can see here, this is the bottom one with the black boot is the 51453 Universal and

22:20the top one is the IC G 653 universal.

22:24And you can see that four of the parts in each, in each one type are,

22:27are actually the same.

22:29So what I wanted to do is make that versatility by having um conversion packs available.

22:34These are much quicker for us to, to manufacture.

22:38Um We can have these stocked on shelves.

22:40Um It means that distributors as also as manufacturers can respond much faster and we

22:47can substitute certain parts. Um So if you look at the,

22:51the 51453 universal that you may have, you may realize that needs to be a Barry Gland,

22:55we can substitute this inner seal and we can substitute this black boot and we can provide

23:01AAA conversion pack with four components. One being a resin stop figure that's got a

23:07seal inside that stops any resin pouring down the inside.

23:10If you were to specify the express liquid resin, you would get the clear compound chamber and

23:15you would get a red deluge boom, then you would also pick whether you want a putty style resin

23:21or whether you want the liquid style now to get up to,

23:25to, for us to be able to do this, we had to work uh closer with our um certification bodies

23:30to ensure that we could mark the product correctly.

23:32So the deciding factor is actually the color of boot that is that is actually installed on the

23:38Glanders when it's finished. Um So the marking actually states 501453

23:43Universal black and IC G 653, universal red. And that gives the ability to mark one product

23:49with two different uses.

23:51Um And gives us the, like I say, the versatility of 22 products within one

23:56potentially.

24:04Perfect. Thank you.

24:05Um Henry or Marty. Do you have anything you'd like to add on the

24:08topic of the conversion kit before I move back into some questions that we've received in the

24:13chat. Um From from my angle, the, the only thing to

24:17be aware of is when we first launched these glands.

24:21Um So right now our inventory here in the US is still split between the

24:27501453 Universals and the IC GS.

24:30Um There is the the move to to try to standardize on 50 ones and then just offer the

24:37conversion kits for the IC GS, but then still have the other available um for those customers

24:44who want to solely purchase the IC GS.

24:46But the inventory we currently have is going to be split between,

24:50um, you know, we're gonna have the AEX IE Ce X and CS A certifications on the

24:5750 ones. And then we'll also have the IC G as a stand

25:00alone gland we with the, we've just recently received the,

25:05the class one div one certifications.

25:08Um, so we will be able to start marking the 50 ones accordingly with the caveat of having the

25:14IC GS with the red de boot.

25:16So, um, those, those are available now, but we would have to get those glands from the factory

25:22out of the UK. So just, we've got a little bit of a time lag

25:25as we work through some of the, uh, the certification, um,

25:29that's done. Uh It's, it's all good.

25:32It's just, we do have a little bit of uh an inventory lag right now and to catch up with

25:36the new certifications and everything. So, just for those,

25:39um, from the US, that's kind of where we stand on our inventory on that,

25:43that products put right now.

25:46And that's perhaps a shorter term thing. We, we are changing to,

25:49to be the, what you're talking about.

25:52Uh So the inventories will get themselves adjusted, but that's a huge thing for the user.

25:57That's, that's a really big thing for the user because he can stock kits in a bunch of glass

26:03and he doesn't have to have two different versions and be out of the wrong one,

26:08right? A great point.

26:12Thank you. Um So I can see that Mike has been answering

26:16some of the questions um, in the chat. Thank you.

26:19Uh Mike. Um, but I think for the sake of everyone that's

26:22on here who's not looked at the chat, I'm just gonna, I'm just gonna refer back to the first

26:26one that we received from, uh Eduardo.

26:29Um, he asks, so concerning the cable used and cable Gland,

26:33is it allowed to have uh, a ceiling ring? Cable gland for class one div one once the

26:38cable is approved,

26:45I'm not sure. I completely understand the question.

26:47Can you try to? Is it in the chapter?

26:49It is indeed. I, I believe if he's saying a ceiling ring is

26:53as though, I mean that in the N AC class one div one is very specific that if you have a

26:59cable gland and cable in that area, the cable gland must be a compound seal cable gland and

27:05in a class one div one area there, there's no, there's no options.

27:10Um So they're, they're very clear in how that has to be applied and it's going into a

27:16threaded entry. So what I, what you mean by a ceiling ring is

27:20what seals it against the enclosure ring. Yes, in the chat.

27:25Ok. So if it's an NPT thread, the likelihood of

27:31that actually engaging is a little lower than if it was straight threads,

27:35straight threaded entries in the north and USA and much of Canada,

27:40we use NPT type threads. So the ceiling ring doesn't do a lot to help

27:45seal the gland against the enclosure is the threads that do that.

27:50I think. Now he was referring to the, to a, to a

27:53compression type seal. So you where you're basically displacing the

27:56seal to seal onto the cable, the ceiling ring.

28:03OK? I mean, either way, obviously, they've got an

28:05answer. They've got two answers there.

28:0711 is if it's an internal, internal compression seal, as in a displacement seal,

28:13then no, in class one, division one, you must use a,

28:16a Barry Gland. And then obviously, if it is, if it is a

28:19ceiling washer, then obviously, that would only be effective on a,

28:22on a metric type thread where you're obviously putting compression between the gland and the

28:27enclosure itself.

28:29One thing to remember when you're installing any hazardous location equipment like explosion

28:36proof or in in zone one, flame proof equipment with cable,

28:41it has to be sealed.

28:42It needs a, it needs a ceiling gland.

28:45Even if the the product is marked factory sealed, the nec requires,

28:50you still have a sealed connector going into that because the assumption is that cable

28:56cannot protect the enclosure. A conduit is different.

28:59You may not need a seal a fact or you don't have to seal a factory seal uh device with

29:04conduit, but you do have to seal that device if it's with cable.

29:08So that's an important thing to remember as well.

29:13Mhm. Um So Mike has thank you for your comments in

29:18the chat there. Uh Mike's made the point that ceiling rings and

29:21compression rings are typically used for ingress protection to keep dust and moisture

29:25out. And Eduardo has said that for IEC they used to

29:30have uh the cable gland for EXD applications with the compression seals and you

29:37can still do that for I see.

29:40Yeah, but that's why he's asking it about mec applications just to clarify.

29:45Yeah. So does that answer your question,

29:48Eduardo, you can respond in the chat if you like?

29:55Perfect. Thank you. OK.

30:01Well, moving back to some of the questions that we were asked via our form,

30:06uh One of the questions we, we get off asked quite regularly is how tight is too tight when

30:12doing up a cable gland.

30:15So Henry if you would like to kick off with that one.

30:17Sure. Um Yeah, that's, that's probably one of the

30:20biggest questions I get, especially when, when we go out and do any type of a gland

30:25termination training.

30:27Um You know, very typical of, of kind of how um I must speak for us guys.

30:33If you see a thread and you still see threads exposed, you have a tendency to just grab a

30:38bigger wrench as it gets tighter and you keep tightening until you don't see any threads.

30:43Um If you do that on a cable gland. You, you definitely have the potential of over

30:47tightening that gland um because it does not require near that,

30:52that amount of force to do that. So we get asked the question,

30:55how tight is too tight and just kind of in accordance with our assembly instruction sheets.

31:01Um You simply just have to tighten the back seal enough to where you form a seal all the

31:06way around your cable and then one full turn with a wrench and that additional turn with the

31:11wrench is just to give it that, that mechanical retention.

31:15Um And so that's probably one of the biggest things we see out in the field is,

31:20is the glands are, are over tightened to the point where you can even see the cable is,

31:25is bulging around all the way around where the seal is in contact with it and stuff like that.

31:31But so, you know, paying attention to the, the assembly and all the gland manufacturers do

31:38things a little different. So it's very important to,

31:41to make sure you understand that going forward on your installations.

31:45But Hawk is very simple in their installations and it's literally form a seal around the outer

31:50jacket in one full turn and to further aid in that what we've also introduced with the,

31:56along with the clear ceiling pot with the new glands, um we've actually removed the spine

32:02from the or the the threads from the middle nut where the,

32:07the back nut comes into contact with the uh the middle nut right here.

32:12And since we did that, we were able to introduce a tightening guide and these,

32:18the dimensions are both in metric and inches.

32:21So now you can simply with the exact same instructions of forming a seal around the outer

32:27jacket one full turn that should put the edge of the back nut in the range of the

32:34ranges that are actually marked on the dimensions marked on the,

32:38on that um between the, the middle nut and the, the back nut.

32:44So it just kind of gives you an additional guide.

32:47Um You know, so if it looks like you've, you check your dimensions and then look at the,

32:52the guide as you're tightening it, it just gives you a reference point.

32:56Um because we also get asked a lot of people ask, well,

32:59do you have any torch specs?

33:01Um It's very difficult for us as a manufacturer to, to give a torch spec because of all the

33:07variances in the cable.

33:09Um We, you know, we manufacture a gland that has global certifications on it.

33:14And as a result, we can deal with all types of different types of jackets,

33:19whether it's thermoplastic thermos set cross link.

33:23Um There's a radiated jackets and all of those jackets are gonna give different types of

33:29yields to, to the compression.

33:31So it's, it's always very important just to make sure you look at those instructions.

33:37But, um, you know, I, I'm probably a little biased because I worked for Hawk for so long.

33:42But Hawk is by far, um, you know, if you follow the instructions,

33:47it's one of the simplest glands out there to put together.

33:50Um, and there's, there's no reason to over tighten these glands with,

33:55uh, the different types of things that we've built into it now with the tightening guide and

33:59some of the, the very simple instructions to do that.

34:02So, um, you know, torque ratings, if we have someone who absolutely has to understand or

34:08want some type of instructions, and we would actually have to test that cable on the gland

34:13and then we could issue torques on that, but it would be very specific to that cable.

34:17Um It's not something that we can just issue out there,

34:20but you really don't need it with the, with the instructions that we provide again.

34:25You know, you tighten until you form a seal one full turn and then you have the addition of the,

34:30of the uh ceiling ranges on the actual tightening guide itself built into the product.

34:36So it's not an extra device or tape or anything else that you have to wrap around the cable.

34:41It's actually built into the gland. So it doesn't require any additional items to,

34:45to figure out if you've tightened it correctly.

34:49You could say that if, if you know, yes, it could overtighten these,

34:53but it doesn't give you a better seal, you know, all the time,

34:56it will still leak water. If, if, if the point you just leave it,

35:00you don't inspect it and nobody ever comes back to it.

35:02Eventually things move, you know, the, the material science happens and,

35:07and materials move between one another and ingress will eventually get in there.

35:11That's what water does. Eventually it's going to get everywhere that

35:14you don't want it to.

35:15Um Which is obviously why we have regular inspections and maintenance and all of them

35:19things. But at the point of installation, you tighten

35:22it enough not to let water in. You know, if you have a,

35:25a tap on your sink, you tighten it, you, you tighten it till the water stops.

35:29You don't have to get your wrench out to, to keep, tighten it until you can't tighten it

35:33anymore. Um So once it is in position, it's tight enough

35:37as per the assembly instructions as per the tightening guide.

35:41Um That is enough to ensure that until the next rou routine,

35:45uh uh maintenance routine occurs, it will be, it will give you enough protection.

35:53Perfect. Thank you, Marty.

35:55Anything that you'd like to add on that topic?

35:59No, II, I agree with the other guys that uh people have a tendency to over tighten stuff.

36:04That's not a good idea that thank you. Um Well,

36:10just going back to the chat uh for those of you that haven't seen some of the questions that

36:14have come in there. Uh, Bob Johnson has asked what thread fread

36:18lubricant does Hawke recommend? If any?

36:25I mean, what, what we would typically recommend is just,

36:28you know, as far as actual thread lubricants, you just wanna make sure you don't use anything

36:32that's going to set up. Um, it cannot be a hardening type thread

36:37lubricant cause that will affect the, um, the ratings of it.

36:41You could potentially, if you were to have to deal with the,

36:44the gland is not gonna function correctly if you use some type of a hardening uh,

36:49lube on the threads.

36:52And again, for those of you who haven't seen that, uh,

36:54Mike has recommended the Killar Lubg series

37:02and it's not good, a good thing to use Teflon tape either that's not really allowed.

37:07No, I mean, from a, from a Hawk point of view, we have done tests on,

37:13um, non setting sealants. Um Hy Lamar being one of them.

37:17Um, if you, you know, miss a miss an IP washer or whatever,

37:21we, we have tested Hy Lamar there, think there's four different varieties of hymma that

37:25can be used. It is a non setting compound ceiling,

37:29um, that can be used on the threads, obviously, if you use a hardly one,

37:31you're potentially blocking flame paths.

37:34Um So yeah, that's, that's something else that we, we've done previous tests on at Hawk to

37:39ensure that we can maintain IP if uh IP washer is, is missed and you don't have to disassemble

37:44everything.

37:50Perfect.

37:52Well, we have about four minutes left. Um So if you wanna get your questions into the

37:56chat, uh before we finish up, um, that would be great.

38:02Um I can see that Eduardo has a couple more questions for my care there.

38:05Um, but I mean, Matt Henry and Marty, are there any other questions that you've generally had

38:11in the field that you'd like to bring up? Now?

38:17Um, about the only thing I, an additional thing, I mean,

38:20you know, the, the topics of over tightening and then of course,

38:23the compound is always gonna be the most popular ones that we see.

38:26But, um, also just I, if you really, just from an overall installation

38:32perspective, you know, refer to the A I sheets, um, the A I sheets are how the cable glands

38:39are certified. It's how we, we submit those same

38:42certifications. I'm sorry, the same A I sheets to the

38:45certifying bodies to get our certifications.

38:48Um There's, there's lots of people will take a lot of interpretations.

38:54Um There's a lot of inspectors that are out there and may not have the same training or may

39:01they assume that one gland can be installed the same way as they think they should all be

39:05installed the same way.

39:07Um So it's very important when you're interacting with your inspectors or you're

39:10doing your installations, you know, the, the A I sheets essentially are your Bible when it

39:16comes to that and any, any type of interactions you're having with,

39:20with inspectors or, or just your
