PEX-AL-PEX pipe combines the best of plastic and metal in a strong, multi-layer tube. Featuring an aluminum core, it holds its shape when bent, allowing for faster, neater installations without the recoil of standard PEX. This aluminum layer also serves as a 100% oxygen barrier, making it ideal for protecting sensitive components in radiant heating systems. With lower thermal expansion and higher pressure ratings, PEX-AL-PEX offers superior stability and durability for any plumbing or hydronic project.
