JG Speedfit Barrier Pipe Straight 28mm x 6m

The JG Speedfit Barrier Pipe Straight 28mm x 6m is a full 6 metre straight length of 28mm PE-X barrier pipe, code 28BPEX-10X6L, for heating engineers and plumbers working on primary pipework, large cold mains and bigger heating systems.

A straight length suits exposed or boxed runs better than coil, because it sits true on the clips with no wave in it. Six metres also lets you cross a plant room or a long cellar wall without a joint. The pipe is white cross-linked polyethylene with five layers and a blue oxygen barrier in the middle, so it can go on sealed and vented heating as well as hot and cold water.

Joints on the JG Speedfit Barrier Pipe Straight 28mm x 6m are made with 28mm Speedfit push-fit fittings and a 28mm insert in every cut end. Two things to plan for at this size: clips every 800mm on horizontal runs and every 1,000mm on vertical runs, and at least a metre of copper from any boiler before the plastic starts. Our JG Speedfit fittings and pipe page has the 28mm tees, elbows and reducers.

Common Questions

How tight can I bend it? Held with clips either side of the curve, the smallest radius Speedfit give for 28mm PE-X is 300mm. Go tighter than that and you should fit an elbow. Never heat the pipe to help it bend.

Can it connect straight onto a boiler? No. Speedfit want at least a metre of copper run from the boiler casing before you change to plastic, unless the boiler maker’s instructions say otherwise. A gravity primary on a solid fuel range should be copper throughout.

How much heat will 28mm pipe carry? Speedfit’s sizing table puts 28mm at about 22kW, based on a flow speed of 1.2m/s and an 11°C drop. Use that as a rough guide when you plan how many radiators a run can feed.

Do I need inserts in the pipe ends? Yes, at every joint. Use a Superseal or standard Speedfit insert going into push-fit fittings, and a standard TSM insert where the pipe goes into a compression fitting, so the olive has something solid to bite on.
