PEX Tubing Oxygen Barrier, Rolls of Red & Blue EVOH PEX-B Pipe for Radiant Floor Heating, Plumbing & Hydronic Systems

Durable & Flexible PEX Tubing with Advanced Oxygen Barrier

Upgrade your radiant floor heating and plumbing systems with this PEX Tubing Oxygen Barrier – 2 Rolls of 1/2 Inch x 300 Feet Tube Coil (Red & Blue). Crafted from non-toxic, crack-resistant EVOH PEX-B pipe, this premium tubing ensures long-term reliability, high temperature resistance, and exceptional flexibility for both residential and commercial applications.

Superior Material Construction
Made from high-quality PEX-B, this tubing is leak-proof, corrosion-resistant, and built to withstand extreme temperatures. The 1/2 inch nominal diameter provides an optimal flow rate for water delivery in heating or plumbing applications.

Advanced EVOH Oxygen Barrier
A triple-layer design includes a middle EVOH layer to block oxygen infiltration. This prevents rust and corrosion in metal system components, making it perfect for closed-loop systems like radiant floor heating.

High Temperature & Pressure Tolerance
Withstands temperatures from -40℉ to 203℉ and pressures up to 160 psi @ 73℉, ensuring peak performance in both hot and cold climates.

Flexible & Easy to Install
Each 300 ft roll bends with a minimum radius of 5", accommodating complex layouts and tight spaces without kinking. Compatible with all major fitting systems:

• Crimp connections

• Cinch (clamp) systems

• Compression PEX fittings

• Press systems like Viega

Whether you’re installing in structural slabs, staple-up systems, or snow-melting setups, this tubing adapts to your project's needs.


Versatile for Multiple Applications

This PEX tubing with EVOH oxygen barrier is ideal for:

• Radiant floor heating systems

• Solar hot water applications

• Snow and ice melt systems

• Central air-conditioning pipe installations

• Potable water plumbing (non-potable use recommended for O2-barrier)
  Perfect for both residential and commercial settings, including "sandwich" radiant flooring (between subfloor and finished floor) or under concrete.

Bring professional-grade performance to your next heating or plumbing project with this PEX Tubing Oxygen Barrier – 2 Rolls of 1/2 Inch X 300 Feet Tube Coil. Ideal for contractors, DIYers, and homeowners who demand both reliability and long-term cost savings.
