This product is designed for use in hydronic radiant heating systems, baseboard heating, and snowmelt applications where oxygen diffusion into the system must be controlled. The oxygen barrier layer on the outside of the tubing prevents atmospheric oxygen from permeating through the pipe wall and entering the water circuit. This protection helps prevent corrosion on ferrous components such as boilers, pump housings, radiators, and manifolds. Without an oxygen barrier, dissolved oxygen in the system water accelerates rust and scaling inside metal components, leading to early equipment failure and costly repairs. The Legend Valve 850-153 addresses this directly, making it a reliable choice for closed-loop hydronic systems.\u003c\/p\u003e\u003cp\u003ePEX-BAR tubing is flexible and easy to handle on job sites. The 300-foot coil gives installers enough continuous length to run radiant floor loops, reduce fitting connections, and minimize potential leak points. The 3\/4 inches outside diameter is a common size used in main distribution lines and larger radiant loops. PEX tubing resists scale buildup, is freeze-damage resistant, and handles both hot and cold water service. It is compatible with standard PEX fittings and crimp, clamp, or expansion connection methods. This tubing is manufactured in Italy and meets quality standards expected for professional hydronic installations. HVAC technicians, plumbers, and mechanical contractors working on in-floor radiant heat, panel radiator systems, or snow and ice melt applications will find this coil ready to perform in demanding closed-loop environments.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOxygen barrier layer prevents oxygen diffusion and protects ferrous system components from corrosion\u003c\/li\u003e\n\u003cli\u003e3\/4 inches outside diameter in a 300-foot continuous coil reduces fittings and speeds installation\u003c\/li\u003e\n\u003cli\u003eSuitable for hydronic radiant heating, baseboard systems, and snowmelt closed-loop applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Legend Valve 850-153 PEX tubing with oxygen barrier provides reliable corrosion protection for closed-loop hydronic systems in a convenient 300-foot coil.
