VIVO 1/2 inch x 500 feet Pex Tubing Oxygen O2 Barrier EVOH, Pex-B Red 500 feet for Radiant Floor Heat (PEX-12H-R050)

1/2" PEX Tubing with Oxygen Barrier (EVOH) is used for residential and light commercial radiant heating applications. With the same properties as PEX non barrier pipes, EVOH PEX barrier pipe keeps oxygen and other elements from infiltrating and corrupting the key mechanical components in heating systems. Tubing is marked every 5ft with length, ASTM standards, approvals, certifications, pressure ratings and other technical information.

Warranty:
Industry standard, 25-year manufacture's warranty.

Applications:
1/2" PEX tubing w/ Oxygen Barrier is common for the following radiant floor heating applications
-Structural concrete slabs (rebar or wire mesh reinforced slabs)
-Non-structural slabs (thermal mass, gypsum slabs)
-Staple-up (between joists) radiant floor heating with and without heat transfer plates
-"Sandwich" types radiant heating (between subfloor and finished floor)
-Snow & ice melting systems
-Baseboard & radiator heating systems
