Professional Grade WRAS Approved Pex-Al-Pex Pipe
WRAS Approved – This pipe has been tested and certified with full UNITED KINGDOM ‘WRAS’ approval – a rigorous testing procedure which certificates only the highest quality products as fit for use in UK domestic water applications.
The WRAS approval determines that this product can be used in all UK domestic plumbing applications including drinking water installations – as well as central heating and underfloor heating applications.
This Pex-AL-Pex pipe is a 5 LAYER Premium pipe that combines the advantages of copper and plastic and eliminates their disadvantages. Multilayer pipes are recognised worldwide as the market leading pipe for underfloor heating systems. Our 5 layer Premium Pex-AL-Pex pipe incorporates an oxygen diffusion barrier and aluminium central core to ensure strength and outperforms older PEXa & PEXb type pipes in all aspects. The 5 layer Pex-AL-Pex Premium pipes are unrivalled in their suitability for underfloor heating systems and, due to their WRAS Approval, are equally suited to drinking water installations.

Our high quality PEX-Al-PEX pipes, or PEX/Aluminium/PEX are unrivalled in their suitability for underfloor heating systems and, due to their high specification, are equally suited to drinking water installations (for which they are WRAS approved and certified). They are made of a layer of aluminium sandwiched between two layers of PEX. The metal layer serves as an oxygen barrier, stopping the oxygen diffusion through the polymer matrix, so it cannot dissolve into the water in the tube and corrode the metal components of the system. It also bends better, because the shape memory of the PEX is offset by the aluminium.
