If it reaches your bubble counter, solenoid or regulator, it can corrode parts and cause expensive damage. The Wyin Aqua Quick Plug CO2 Check Valve sits in your CO2 line and only lets gas travel one way, so water can't get back to your gear.\u003c\/p\u003e\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eCO2 flows through in the direction of the arrow. If anything tries to come back the other way, the valve closes. The quick plug ends grip standard 4\/6mm CO2 tubing as soon as you push it in, so there are no nuts or clamps to deal with.
