JG Speedfit PEX barrier pipe coil is flexible making it easier to run longer pipe runs. The flexibility of the pipe reduces the need for push-fit fittings significantly compared to traditional copper pipe systems, which in turn delivers labour and cost savings. It has 5 layers, the centre of which is a blue coloured oxygen barrier that prevents the ingress of air into the system, reducing the effect of corrosion on metal components. Due to its low thermal conductivity, when carrying hot water, PEX pipe is cooler and therefore safer to touch. Designed, manufactured and assembled in the UK.
