INTBUYING 300 Ft PEX Tubing – 3/4" Oxygen Barrier Pipe For Radiant Floor Heating & Plumbing, ASTM Standard

About This Product

Planning a radiant floor heating system or a plumbing project? This 300-foot coil of 3/4\ PEX tubing is a professional-grade solution. It's PEX (cross-linked polyethylene) tubing with an oxygen barrier (EVOH layer), which is essential for closed-loop heating systems because it prevents oxygen from corroding your boilers, pumps, and other metal components, dramatically extending the system's life. The specs are spot-on: 3/4\ nominal size, 0.88\ outside diameter, 0.68\ inside diameter. It's incredibly flexible with a minimum bending radius of just 7 inches, making it easy to snake through floor joists and around obstacles without kinking. It handles high temperatures and pressure (up to 230°F and over 180 PSI at room temp). The smooth interior resists scale buildup and ensures excellent water flow. It's compatible with most common connection methods: crimp, cinch (clamp), press, or compression fittings. Use it for in-floor radiant heat, snow melt systems, domestic hot and cold water supply, or even solar heating. A versatile, durable, and reliable choice for DIYers and pros working on residential or commercial projects.
