CO2Art Precision Check Valve Protect your CO₂ system with the CO2Art Precision Check Valve, designed to prevent water from flowing back into your regulator or solenoid. This simple but essential component helps protect expensive CO₂ equipment from potential water damage. Built to handle high-pressure CO₂ systems (100+ PSI), the valve allows CO₂ to flow in one direction while stopping any reverse flow from your aquarium. With an extremely low opening pressure of just 1 PSI, it allows smooth CO₂ flow without restricting your bubble rate. The easy push-in connectors make installation quick and straightforward, allowing it to be added inline with your CO₂ tubing in seconds.
