Description

The Legend CO2 Check Valve prevents the aquarium water from flowing back after the CO2 system has been switched off for the night. Due to the lack of pressure, the aquarium water can migrate into the CO2 hose and reach the pressure reducer without a check valve due to cappilar forces. It is therefore always sensible to integrate a non-return valve into the CO2 supply.

The hose connection on both sides is designed for 4/6 mm CO2 hoses. The valve is integrated into the system so that the arrow points in the direction of the gas flow.

Features

• High-quality non-return valve prevents backflow of water
