Contact SupplierPEX (or crosslinked polyethylene) is part of a RO Water, Acid & Bicarb concentrate supply piping system that has several advantages over metal pipe (copper, iron, lead) or rigid plastic pipe (PVC, CPVC, ABS) systems. It is flexible, resistant to scale and chlorine, doesn't corrode or develop pinholes, is faster to install than metal or rigid plastic, and has fewer connections and fittings.
PEX-Al-PEX (or PEX-Aluminum-PEX or "PAP") is a specialty PEX tubing. This tubing has a layer of aluminum embedded between layers of PEX to provide an oxygen barrier. PEX-Al-PEX may also be called multilayer pipe. PEX-Al-PEX will also retain shape when bent, and may also exhibit less expansion and shrinkage during temperature fluctuations.
PEX tubing is made from crosslinked PE (polyethylene) polymer. The PE is melted and continuously extruded into tube. The crosslinking of the PE is accomplished in one of three different methods.
