Built for high-efficiency heating systems, this 1000 FT roll of 1/2" PEX Tubing with Oxygen Barrier (Model PEX1258) is engineered to deliver consistent performance in radiant floor heating and hydronic applications. Its five-layer construction resists corrosion, cracking, and oxygen infiltration—extending the lifespan of metal components in your system. Flexible, durable, and easy to install around tight corners and long runs, it's a must-have for contractors and serious DIYers tackling large-scale plumbing or heating projects.

💡 Why It Stands Out:

• 5-layer PEX-b construction with EVOH oxygen barrier

• Withstands extreme temps & pressures in closed-loop systems

• Flexible design minimizes joints & speeds up installation

• Approved for radiant heating and hydronic baseboard setups

• 1000 FT continuous coil ideal for whole-home or multi-zone installs
