LavaTap 22 mm x 50 m White PEX Barrier Pipe is a WRAS-approved solution for both plumbing and heating systems. This 50-metre coil of cross-linked polyethylene (PEX) pipe features an integrated oxygen barrier layer that reduces the risk of corrosion in central heating circuits, helping to extend the life of system components. Designed for versatility, this 22 mm barrier pipe is suitable for hot and cold water plumbing as well as central heating applications. The smooth internal bore ensures efficient water flow with minimal pressure loss, while the tough multi-layer construction resists kinks, abrasions, and temperature fluctuations. Lightweight and flexible, the pipe is easy to cut, handle, and install. It is fully compatible with standard UK push-fit and compression fittings, making it ideal for both professional installers and DIY projects. For added convenience, this 50 m PEX pipe includes clear 1-metre markings along its length, allowing faster, more accurate measuring and cutting. Approved for use in potable water systems, it offers a reliable and maintenance-free alternative to copper plumbing pipe.
