Legend Valve 850-161 Pex Tubing with Oxygen Barrier 1 Inch 100 Foot Coil

Product Description

The Legend Valve 850-161 is a 1 inch PEX tubing with oxygen barrier, supplied in a 100 foot coil and manufactured in Italy. This tubing is designed for radiant floor heating, hydronic heating systems, and other closed-loop plumbing applications where oxygen diffusion into the system must be controlled. The oxygen barrier layer bonded to the outer wall of the tube prevents atmospheric oxygen from permeating through the polymer wall and entering the water circuit. Oxygen infiltration in hydronic systems accelerates corrosion in ferrous components such as boilers, manifolds, pump housings, and cast iron radiators. Using oxygen barrier PEX tubing is a standard practice among professional plumbers and hydronic heating installers to protect system longevity and reduce maintenance costs. The Legend Valve 850-161 is constructed from a durable polymer tube material that handles the thermal cycling common in heating applications. With a 1 inch outside diameter, this tubing is well suited for main distribution runs in radiant systems and for connecting to manifolds in larger residential and commercial installations. The flow capacity of 0.0312 gallons per foot allows installers to calculate system volume accurately for proper glycol charging and expansion tank sizing. The 100 foot coil length reduces the number of fittings and joints required on longer runs, lowering labor time and potential leak points. At 16 pounds per coil, it is manageable on the job site. Trade professionals working on hydronic radiant heat, snow melt systems, or closed loop domestic heating loops will find this tubing meets standard installation requirements for oxygen barrier PEX.

• Oxygen barrier layer prevents oxygen diffusion and protects ferrous system components from corrosion
• 1 inch outside diameter in a 100 foot coil suits main distribution runs and larger radiant heating layouts
• Flow capacity of 0.0312 gallons per foot supports accurate system volume and glycol calculations
