CO2 non-return valve

This CO2 check valve reliably prevents water from the aquarium or CO2 system from flowing back to the pressure regulator or solenoid valve. An essential safety component for any CO2 system.

Safe protection of your CO2 system

When the CO2 supply is turned off, negative pressure can build up, causing aquarium water to be sucked back into the hose. This check valve effectively blocks this backflow, protecting valuable components of your CO2 system from water damage.

Key Features

• Reliable CO2 non-return valve
• Prevents backflow of water towards the regulator or solenoid valve
• Suitable for CO2 installations in aquariums
• Compact design, easy to place in the CO2 hose
• High quality from TUNZE

Application

Place the check valve in the CO2 hose between the aquarium and the CO2 regulator, with the arrow pointing in the direction of the gas flow. This will keep your system functioning safely and reliably.

Suitable for

• Freshwater aquariums with CO2 fertilization
• Professional and hobby CO2 systems
