AquaHeat Pex-A pipe with Oxygen barrier.

Tubing is made using the Engel method. The Engel method is a hot cross-linking process, meaning the actual cross-linking takes place during the extrusion process when the base polyethylene is above its crystal melting temperature. The Engel method provides more precise control over the degree, consistency and uniformity of cross-linking. This means the tubing is evenly cross-linked, with no weak links within its molecular chains. Available in 3/8”,1/2”, 5/8”,3/4” & 1” pipe sizes.
