32mm MLC Pipe - 50m Coils - WRAS Approved

33mm Multi-Layer Composite Pipe (MLCP)

Multilayer pipes consist of an inner PEX-b layer (polyethylene mesh), an aluminum middle layer welded lengthwise (head-head) with laser/TIG technology and an outer white PEX-b layer. The adhesive middle layers join the aluminum and PEX-b layers homogeneously.

The aluminum layer provides a safe barrier against oxygen and other gases along with an outstanding resistance to crushing. Multilayer pipes are fit for domestic water, heating and cooling systems according to standard EN 21003.
