About GasBreaker
GasBreaker Excess Flow Valves have provided industry-leading service to commercial and residential areas since their initial conception as a UMAC product in 1974. UMAC was founded in 1970 with a mission to provide reliable, highly functional gas breakers to protect homes and businesses.
The following 30 years saw UMAC establish itself as a pioneer in the gas industry, introducing a number of groundbreaking valves, including the first plastic-to-plastic EFV in 1976, a medium-capacity EFV in 1990, and the first no-hole EFV in 2006.
