Stainless Steel Check Valve for Planted Aquarium CO2 Systems

Stop water from leaking & damaging your CO2 regulator when the power is off. Made with stainless steel for greater durability and to handle high pressures.

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.

The best way to position a check valve is near the top of your aquarium. This stops the water at the rim instead of down near the pump where over time the pressure could cause a leak. Make sure your airline tubing is cut nicely and free of any tears. Check to make sure the tubing hasn't dried out over time causing the connection to be loose as this will leak in the event of a power outage.
