PEX tubing with oxygen barrier

This Legend Valve tubing comes in a 1000 foot coil weighing 40 lbs. It carries water for hydronic heating or potable plumbing systems. The oxygen barrier limits corrosion in ferrous components such as boilers and circulators.

Fits standard 3/8 inch PEX fittings and tools

The coil unrolls for long continuous runs that reduce the number of joints required. Each foot holds .0051 gal. of fluid, so installers can calculate total system volume directly from the length used.

Sustained pressure and temperature cycles

The oxygen barrier maintains its performance over the life of the system rather than degrading after initial exposure. The product carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm.

Questions about this item

What is the maximum pressure this 850-129 PEX tubing can handle during continuous operation?

The tubing is rated for 40 lbs capacity, which represents its pressure limit under sustained use.

Does the oxygen barrier or tubing material affect heat retention when hot water circulates all day?

The oxygen barrier helps prevent corrosion in heating systems, and the PEX material resists scale buildup that can reduce thermal efficiency over time.

What fittings or tools are required to install this 3/8 inch PEX tubing?

You will need compatible 3/8 inch PEX fittings such as crimp, clamp, or push-fit types, plus the appropriate crimping or expansion tool for the connection method chosen.
