The ultimate multi-seal connection

Ultra flexible plastic pipe

JG Layflat Polybutylene Barrier Pipe is lightweight and flexible, making it easier and quicker to manoeuvre through joists and tight spaces. Longer pipe runs mean reduced labour costs and potential leak points.

Dual Superseal pipe insert

The dual O-Rings in our Superseal Pipe Inserts together with the O-Ring in our fittings create a unique, leak-tight, multi-seal connection you can rely on.

I always install JG Speedfit on new build sites and existing works due to the reliability of the fittings. I do not have any product faults or leaks. I enjoy the Twist and Lock^® feature as it adds an extra element of security knowing the joint has been compressed by the locking feature. This leads to firmer connections compared to other push-fit alternatives.

Steve Minter, Elveys Plumbing and Heating

We specify JG Speedfit on all our developments. The Twist and Lock^® fittings are secure, the pipe is flexible and when used together we have complete confidence in the quality.

The quality and consistency of JG Speedfit pipe and fittings has been so good it’s been our preferred choice for the past 20 years, regardless of whether we’re using it on a large new build construction site or an established individual home renovation.

We have been a loyal JG Speedfit user for many years and their JG Layflat Pipe is a big advantage to us. It is very flexible and makes installation easier and quicker. JG Speedfit is a brand we can trust and the fittings combined with the pipe make for a quality installation.
