Stainless Check Valve
Implement preventative measures in your aquarium set up with the use of this Stainless Check Valve, offered by Ista. Recommended for CO2 systems, this Stainless Check Valve ensures the function and longevity of your CO2 bottle. With its installation you can protect your equipment in instances where the CO2 pressure lessens, allowing water to flow back inside the tubing.
