These check valves are the perfect solution to backflow issues that you may be having. They go on the gas side of a ball or pin lock gas system. They have an integrated back check valve that helps prevent flow from reversing, and fit on the 1/4" MFL fitting found on most standard ball or pin lock disconnects. Keep your gas lines clean with these as a preventative measure.
