SMC Bushing Style 1/4" Check Valve
1/4 NPT Male Outlet - 1/4 NPT Female Inlet
A check valve allows flow in one direction, but prevents back flow in the other direction. These SMC Check Valves can be placed between your tank and compressor to prevent pressure from leaking back through the compressor. For best results, mount near the tank before the water trap to keep it pressurized for draining.
