Uponor Composite Tubing, 3/4 in Nominal Size, 0.792 in Inside Dia, 0.99 in Outside Dia, 500 ft Coil Length, 145 psi Working, 203 to 230 deg F, PEX, White

Multi-layer composite (MLC) tubing consists of interior aluminum tubing lined with inner and outer layers of PEX. MLC tubing offers 100% oxygen diffusion. The stay-in-place rigid feature of the tubing works great for hydronic baseboard, radiators, unit heaters, air handlers or manifold connections. Uponor MLC tubing is manufactured to the following standard: ASTM F1281 "Standard Specification for Cross-linked Polyethylene/Aluminum/Cross-linked Polyethylene (PEX-AL-PEX) Pressure Pipe". Tubing is rated and listed by the Hydrostatic Stress Board of PPI at 200 deg F at 100 psi, 180 deg F at 125 psi, 140 deg F at 160 psi, and 73 deg F at 200 psi.
