PEX/AL/PEX piping is a coextruded crosslinked polyethylene composite pressure pipe with a welded aluminum tube reinforcement between the inner and outer layers. The inner and outer crosslinked polyethylene layers are bonded to the aluminum tube by a melt adhesive.

Jun 23, 2024 · PEX-AL-PEX pipes revolutionize plumbing with their composite structure of PEX layers bonded by aluminum, offering flexibility, durability, and high resistance to temperature and pressure. Ideal for potable water, underfloor heating, and solar thermal systems, they combine strength and ease of installation.

Sep 19, 2013 · PEX-Aluminum-PEX (PEX-AL-PEX) tubing contains a layer of aluminum embedded between two layers of PEX. SupplyHouse.com carries standard PEX-AL-PEX made by Rifeng and Uponor. The aluminum serves as an oxygen barrier and makes the tubing more rigid.

Jun 19, 2000 · The name isn't very catchy, but PEX-AL-PEX has the benefits of both metal and plastic pipe. I was first introduced to a multi-layer PEX-AL-PEX pipe about 15 years ago. A company executive explained to me how the pipe was made and how they planned to distribute it in North America.

Oxygen Barrier PEX and PEX-AL-PEX are both types of crosslinked polyethylene (PEX) tubing with distinct differences and are used for different applications. Oxygen Barrier PEX tubing, on the other hand, is a type of PEX tubing designed explicitly for heating applications.

PEX-AL-PEX, also called Aluminum PEX, is a 3-layer oxygen barrier PEX tubing. This tubing has an aluminum core that holds its shape when bent so you don't have to tie it down every few feet like traditional PEX tubing.

What is PEX-AL-PEX Tubing? Multi-layer PEX or PEX-AL-PEX, as the name implies, is a tubing where an aluminum core layer is sandwiched between 2 layers of PEX. This feature allows it to expand less at high temperatures and hold its shape better than regular PEX.

Feb 21, 2022 · PEX-ALUMINUM-PEX Composite, also known as PEX-AL-PEX, is a polyethylene pipe that has an aluminum lining between the inner and outer layer. A melt adhesive is used to bond the aluminum to the layers of the pipe.

Dimensions, pressure ratings, elongation, certifications, approved connections methods and other properties of PEX-AL-PEX tubing in 3/8", 1/2", 5/8", 3/4" and 1" sizes.

May 11, 2017 · The only PEX fittings that have a specific type of PEX are expansion fittings. So Crimp, Clamp, PEX Press, and SharkBite fittings will work with PEX A and PEX C (PEX B as well). The only type of PEX that has its own fittings is PEX-AL-PEX.
