Cutting torch check valves fit on the end of the torch between the torch and 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. Show more
