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.

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.

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.

PEX/AL/PEX piping is a high-temperature flexible plastic pressure pipe with over 30 years of successful use in the European market, including extensive testing for durability and material performance. It was first introduced in North America in the early 1990s.

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.

When comparing pex-al-pex vs pex-b, remember that both are excellent products—just designed with slightly different strengths. Understanding these differences helps you match the right pipe to your specific situation, maximizing both performance and value.

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 ...

MrPEX® PEXAL- PEX tubing is certified by NSF (NSF-rfh) and temperature/pressure rated by the Hydrostatic Stress Board of PPI (Plastics Pipe Institute) in accordance with ASTM F 1281‑2005 (CSA B137.10) to 160 psi at 200°F.

This category contains PEX-Aluminum-PEX (PEX-AL-PEX) tubing used in radiant floor heating systems. PEX-AL-PEX contains an aluminum inner layer which allows tubing to bend easily around turns and hold its shape. PEX-AL-PEX is available in several sizes and lengths.
