PEX-AL-PEX, or AluPEX, or PEX/Aluminum/PEX pipes are made of aluminum strip sandwiched between two layers of PEX. The welded metal serves as an oxygen barrier to avoid corrosion of metallic parts found in the surrounding heating system. The thin aluminium layer provides some rigidity to the tube, which allows it to be shaped. The aluminium layer also provides structural resistance in order to safely withstand higher operating temperatures and pressures. The product is considered as the highest quality product for it's application.
