The AQUAPRO Aluminium Alloy CO₂ Check Valve is a compact, high-quality non-return valve designed specifically for pressurised aquarium CO₂ systems.
Installed inline on your CO₂ tubing, the valve allows CO₂ to flow in one direction while helping prevent aquarium water from siphoning backwards towards your regulator, solenoid and CO₂ cylinder when the system is switched off or loses pressure.
Manufactured from durable aluminium alloy, the valve features secure locking connectors on both ends to provide a neat and reliable connection to standard 4/6 mm CO₂ tubing.
