  • Durable Stainless Steel Construction

This check valve can only be used with a pressurized CO2 cylinder. The air from a regular air pump will not be able to pass through it.

A check valve is used within airline tubing to prevent water from siphoning out of an aquarium and into a CO2 regulator. Stainless steel check valves are durable and will hold up over time keeping your equipment safe from leaks. A stainless steel check valve is the best choice when using CO2 as it will hold up better than plastic over a long period of time.

The arrow on the check valve indicates the direction of airflow.

It's a check valve

Nice machining.

I didn't have one on my CO2 system. Sometimes you don't know you need something and thats what I love about the Co-op. I can trust if they are offering it is likely something I need. Very nice machining. My day gig involves some machining and I can tell it is well made.

Works Fine

I installed this "upstream" from my Aquarium Coop CO2 regulator. It seems to work as advertised.
