(2)O2 Barrier Pipe-in-Pipe is HeatLink® O2 Barrier PEX-a tubing that has been inserted into a protective sheath. The flexible, impact resistant PP sheath designed as a raceway for electrical installations provides mechanical and UV protection to the PEX-a carrier tubing. The sheath allows for easy replacement of the PEX-a carrier tubing if needed.HeatLink--O2Barrier-Pipe-in-Pipe.jpg
