RAUPEX O2 barrier PEXa pipe provides an extra layer of protection with its co-extruded ethylene-vinyl alcohol (EVOH) oxygen diffusion barrier, which limits oxygen permeability. The main component in the hydronic and radiant heating and cooling systems, this durable yet flexible PEXa pipe offers enhanced temperature/pressure capabilities and long-term strength.
RAUPEX is freeze break resistant and actually expands when frozen; pipes are not likely to burst when exposed to freezing conditions.
RAUPEX O2 Barrier Pipe is manufactured using REHAU’s high-pressure peroxide method for cross-linked polyethylene (Engel method, PEXa). RAUPEX O2 Barrier Pipe has a co-extruded oxygen diffusion barrier that exceeds the strict requirements of DIN 4726. All RAUPEX O2 Barrier Pipe meets or exceeds the requirements of ASTM F 876, F 877, CSA B 137.5 and PPI TR-3, and is certified to NSF Standards 61. RAUPEX O2 Barrier Pipe also meets the requirements of ASTM F 2023 for chlorine resistance and is produced in REHAU’s ISO 9001 certified manufacturing facilities. RAUPEX O2 Barrier Pipe is rated for continuous operation of:
- 160 psi @ 73.4°F (1105 kPa @ 23°C)
- 100 psi @ 180°F (690 kPa @ 82.2°C)
- 80 psi @ 200°F (550 kPa @ 93.3°C)
RAUPEX O2 Barrier Pipe is compatible with RAUPEX compression nut fittings and EVERLOC compression-sleeve fittings certified to ASTM F 2080 and CSA B 137.5.
