The moment an air stone or CO2 diffuser is no longer supplied with CO2 or air, the pressure drops. This creates the chance that water siphons down through the air stone through the hose, with all the consequences that entails. Use the Azaqua Non-return valve to prevent water from siphoning out of the aquarium.
The non-return valve is made of plastic. The direction is clearly marked on the top for easy installation. Suitable for standard CO2 hose and air hose with 4/6mm diameter.
Azaqua Non-return valve is suitable for CO2 hose (flexible and pressure hose), Air hose, but also for liquids.
