Product Details
This aquarium air line tubing is designed to carry air from your pump to air stones, ornaments and other aeration accessories, helping improve oxygenation and water movement. It’s a simple, dependable way to refresh an existing setup or build a new air line run with a tidy finish.
Made from flexible PVC, the tubing is easy to route around corners and along the back of an aquarium, while keeping a secure push-fit connection on standard air pump and accessory nozzles. The clear finish helps it blend into most tank layouts and makes it easier to spot air flow issues.
Suitable for most common aquarium air pumps and air line accessories that use the standard 4mm bore connection. Choose the length you need for your tank size and layout, whether you’re running a single air stone or feeding multiple points via suitable connectors.
Ideal for freshwater and marine aquariums, as well as small pond or water feature aeration where standard aquarium air line fittings are used. Pair with check valves and air stones as required for your setup and to help prevent backflow during power interruptions.
