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.

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.

PEX-AL-PEX differentiates itself from standard PEX with its Aluminum core. This allows it to expand less at high temperatures and hold its shape better than regular PEX. Shopping for …

May 11, 2017 · PEX-AL-PEX The most expensive of the bunch, PEX-AL-PEX, also known as aluminum-barrier PEX, features a special construction—namely, an aluminum layer that goes a long way to help the tubing keep its shape once bent. That means PEX-AL-PEX eliminates the need for the installer to employ tie-downs every few feet.

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.

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.

Jun 19, 2000 · With PEX-AL-PEX, the aluminum inner layer keeps the pipe rigid, as if it were a metallic piping system. Unlike metallic pipe, it can bend easily in your hand and take the shape …

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.

PEX-AL-PEX tubing is a composite type tubing comprised of 3 layers (PEX, Aluminum and PEX) bonded together. Since aluminum is impermeable to oxygen, it acts as an effective oxygen diffusion barrier and eliminates the need for an additional EVOH layer (as in barrier PEX), making it suitable for hydronic and radiant heating applications ...

Dec 11, 2024 · PEX pipes are ideal for systems requiring flexibility and heat resistance. On the other hand, PEX-AL-PEX pipes provide additional strength and corrosion resistance due to the aluminum layer, making them suitable for closed-loop hot water systems and other applications where oxygen barrier properties are crucial.
