1/2" Red Pex Tubing 500ft Roll / Oxygen Barrier EVOH Pex-B

Product Description
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.

  • 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
Standards, Certifications & Approvals:

  • ASTM F876: Standard Specification for Crosslinked Polyethylene (PEX) Tubing
  • ASTM F877: Standard Specification for Crosslinked Polyethylene (PEX) Plastic Hot- and Cold-Water Distribution Systems
  • CSA B137.5: Cross Linked Polyethylene (PEX) Tubing Systems for Pressure Applications
