Product description
One-way check valves for compatible aquarium air-pump and airline setups. They help reduce water back-siphoning through the airline if the pump stops.

- Size options: 3 mm, 4 mm, 6 mm, 8 mm, or 10 mm inner-diameter tubing
- Material: Supplier-listed plastic
- Color: White
- Use: Install in compatible aquarium airline between the pump and aquarium, following the valve's flow-direction marking
Before ordering: Select the size that matches your airline's inner diameter. The listed size options are not interchangeable. This listing is for five check valves only; an air pump, airline tubing, and air stone are not included.
Care: Inspect valves periodically and replace any that become blocked, cracked, or fail to prevent backflow.
