Burtons 30m Black Pond Airline – 8mm x 12mm

Burtons 30m Black Pond Airline – 8mm x 12mm

A full roll of larger-bore black airline for pond and filter aeration

This Burtons black airline has an 8mm internal diameter and 12mm external diameter, supplied as a 30 metre roll. The larger bore is intended for pond air systems where standard small aquarium tube would create too much restriction, particularly on longer runs or higher-output pumps.

Black tube is discreet around pond edges and filter houses, and the continuous roll reduces the number of joints needed between the pump, manifold and diffuser.

Our practical advice: route airline as carefully as water pipe. Avoid tight bends, crushed sections and unnecessary connectors; every restriction increases back pressure and reduces the air that reaches the pond.

Key details

• Roll length: 30 metres
• Internal diameter: 8mm
• External diameter: 12mm
• Black finish for discreet pond and filter installations
• Suitable for compatible Burtons taps, manifolds and air diffusers

Planning the air run

Keep the route as short and direct as practical, protect it from sharp edges and leave enough slack to service the pump or diffuser. Support vertical drops so the airline does not pull off its fitting. Where the air pump is below water level, use the correct non-return arrangement and follow the pump manufacturer instructions.

Check every connector against the stated inside and outside diameters; an “8mm” description can refer to different parts of a fitting. See our airpump accessories for compatible control valves and diffusers.

Frequently asked questions

Is 8mm the inside diameter?

Yes. This tube is listed as 8mm internal diameter and 12mm external diameter.

Can I bury it?

Protect any buried or concealed airline inside suitable ducting so it cannot be crushed and can be replaced later.

Will a larger bore improve output?

On long runs it can reduce friction compared with narrow tube, but the pump, depth, fittings and diffuser still determine the final airflow.

Can I cut the roll?

Yes. Use a clean square cut and make certain the chosen fitting grips the 12mm outside diameter securely.

Why is the product image a labelled reference image?

The current manufacturer catalogue does not provide a suitable high-resolution product photograph for this line, so we have used a clear, accurate labelled image rather than showing a misleading substitute.

Match the airline to the diffuser and air pump

This 8mm-bore line is a useful match for the Burtons ceramic pond air stones, provided the chosen fittings suit both components. Select a pond air pump by airflow at the actual water depth and the diffuser’s resistance—not its zero-pressure output alone.

For shorter runs or different connection sizes, compare the other airline, manifolds and airpump accessories before reducing or adapting the line.
