Clean, flexible airline for connecting air pumps to air stones, diffusers and hydro systems.
This airline tubing is a simple essential for any reservoir or DWC setup. Use it to run air from your pump to an air stone, manifold, or diffuser, keeping lines tidy and helping deliver consistent aeration where you need it. It is easy to cut to length, quick to route around tanks and shelves, and ideal for replacing old lines that have hardened or become stained over time.
Best for
- Air pumps to air stones and diffusers
- DWC, RDWC and reservoir aeration
- Manifolds, splitters and check valve setups
- Replacing worn tubing to restore reliable airflow
Why it’s worth doing properly
- Cleaner setup: neat routing reduces kinks and messy tangles.
- More reliable airflow: fresh tubing helps avoid restrictions caused by old, hardened lines.
- Easy to work with: cut to length and push-fit onto standard airline fittings.
How to use
- Measure the run and cut the airline cleanly to length.
- Push-fit onto your air pump outlet, check valve, splitter or manifold.
- Keep runs as short and straight as practical and avoid sharp bends.
- If you are running a reservoir, add a check valve to help protect your pump.
Tip: If your air pump sits below the waterline, a check valve is cheap insurance. It helps prevent back-siphoning if the pump is switched off.
Sold by length: select the quantity you need and cut to suit your setup.
