Check Valves

Check valves stop the reverse flow of gas to the tank, greatly reducing the chance of a dangerous tank explosion. These check valves should be installed between the regulator and the hose. Both valves feature 9/16" (18 STD B Fittings) connections and are compatible with select Smith and Uniweld regulators.
