- Designed for Pressurized CO2 Systems
- Prevents Water Siphoning Out of Aquarium
- Durable Stainless Steel Construction
- Essential for Power Outages
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.
exactly what I expected, thank you!
CO2 Stainless Steel Check Valve
This works very well. I really like it.
Great quality, works like it's supposed to.
Build quality seems good. Does exactly what it’s designed to do. Another win for the Co-op
