Legend Valve 850-151 Pex Tubing with Oxygen Barrier 3/4 Inches 100 Foot Coil

Product Description

The Legend Valve 850-151 is a 3/4 inch PEX tubing with oxygen barrier, sold in a 100 foot coil. It is designed for use in radiant floor heating systems, hydronic heating loops, and other closed-loop plumbing applications where oxygen intrusion must be prevented. PEX tubing with an oxygen barrier is a standard requirement in hydronic systems because dissolved oxygen in the water can cause corrosion in metal components like boilers, pumps, and manifolds. This tubing meets that need by incorporating a barrier layer that blocks oxygen diffusion through the pipe wall. The 850-151 is manufactured in Italy and is made from a durable polymer material built to handle the demands of residential and commercial heating systems. At 3/4 inches outside diameter, this coil is a common size used by plumbers and hydronic heating contractors for main supply and return lines in radiant heating installations. The flow capacity of 0.0189 gallons per foot makes it easy to calculate total system volume for proper fluid balancing and antifreeze concentration. Each coil weighs approximately 10 pounds, making it manageable on the job site. Legend Valve is a well-known name in the plumbing and hydronic trade, and the 850-151 is a reliable choice for professionals who need consistent quality in their barrier PEX supply. This tubing is compatible with standard PEX fittings and tools used in the trade, including crimp, clamp, and expansion-style connections. It is suitable for in-floor radiant heat, baseboard heating loops, and snow melt systems.
