Cutting Torch Check Valves

Cutting torch check valves fit on the end of the torch between the torch & twin welding hose. They prevent the reverse flow of gas back through the hose toward the tanks. This is a necessary safety measure since most cutting torches as sold without check valves on them to make the price more attractive. These are "B" sized check valves for 3/16, 1/4, 5/16 and 3/8 twin welding hose.
