The John Guest Speedfit white cross-linked polyethylene barrier pipe's 15 mm x 6 m flexible length makes it simpler to run longer pipe lengths. When compared to standard copper pipe systems, the pipe's flexibility considerably reduces the requirement for Push-Fit fittings, which results in labour and cost savings. The John Guest Speedfit white PEX barrier pipe length is constructed of five layers, the middle of which is a blue-coloured oxygen barrier that prevents air from entering the system and lessens the impact of corrosion on metal components. PEX pipe is cooler and safer to handle when carrying hot water because of its low thermal conductivity.
