What an electrofusion end cap is for
An electrofusion end cap closes the end of a polyethylene pipe permanently. The heating wire in its body is heated by an electrofusion unit and the cap fuses to the pipe. It is used at the ends of gas lines, on lines that will be extended later and on unused branches.
Its advantage over a butt-fusion cap is that the pipe does not have to be clamped in a machine; so it can be fitted in a narrow trench, next to a building or on a pipe that is already buried.
Sizes and ordering
The electrofusion end cap is listed in 20, 25, 32, 40, 50, 63, 75, 90, 110, 125, 140, 160, 180, 200, 225 and 250 mm. The cap diameter must match the pipe outside diameter.
In your order give the diameter, the application (water or gas) and the quantity. If you have no electrofusion unit, add a suitable one to the same list, or for small water lines consider a compression end cap.
Fitting tips for electrofusion caps
Before fusing a cap, cut the pipe end square, scrape the outer surface in the fusion zone and clean it with a suitable cleaner. The pipe must go fully into the cap; mark the insertion depth on the pipe before fusion.
On gas lines, follow the pressure test and the local gas company's rules before closing the end. If the line will be extended later, leave a little extra length behind the cap so it is easy to cut off and join new pipe. If a small water line only needs a temporary closure, a removable compression cap is the simpler choice.

Electrofusion End Cap — FAQ
Can an electrofusion cap be removed later?
No; the joint is permanent. To extend the line, the pipe is cut behind the cap.
Which sizes are supplied?
From 20 to 250 mm.
Is it suitable for gas?
Yes; it is listed to EN 1555-3 for gas networks.
What can be used instead?
A butt-fusion end cap on large diameters or a compression end cap on small water lines.
