Watts Radiant 81007367 O2 Barrier Pex Tubing 1 Inch X 20 Foot PB032161-20

Product Description

The WATTS RADIANT 81007367 is a 1-inch diameter O2 Barrier PEX tubing supplied in a 20-foot length. It is designed for hydronic heating systems, radiant floor heating, and other closed-loop heating applications where oxygen infiltration is a known threat to system integrity. PEX tubing, or cross-linked polyethylene tubing, is a flexible pipe material widely used by HVAC technicians and plumbers because it bends easily around obstacles, resists scale buildup, and handles thermal expansion well. The oxygen barrier layer on this tubing is a critical feature for any closed-loop system. Without an O2 barrier, dissolved oxygen enters the water stream and accelerates corrosion on ferrous components such as cast iron boiler sections, steel manifolds, and iron pump housings. The barrier on the 81007367 blocks this oxygen transmission, protecting the entire system and reducing long-term maintenance costs. At 1 inch in diameter, this tubing is well suited for main supply and return runs in residential and light commercial radiant heating installations. Hydronic baseboard heating loops, staple-up radiant floor systems, and in-slab radiant floor systems are all common applications. The flexible nature of PEX allows installers to make long runs with fewer fittings, which reduces potential leak points and speeds up installation time. HVAC professionals and plumbers working on new construction or retrofit hydronic projects will find this tubing straightforward to work with using standard PEX crimp, clamp, or expansion fittings rated for 1-inch connections. The 20-foot length is practical for targeted repairs or short loop segments without requiring a full coil. This tubing performs reliably across the temperature and pressure ranges typical of residential hydronic heating systems.

• Oxygen barrier layer prevents O2 infiltration and protects ferrous system components from corrosion
