R-Flex Insulated Outdoor Radiant PEX Tubing Coil, Single Tube - 328'

Watts Radiant R-Flex Insulated Outdoor Radiant PEX Tubing Coil, Single Tube - 328' Coil, 75mm (3") Tube, 200mm OD A solid proven system R-flex is a pre-insulated, flexible, energy-saving PEX piping system with a durable, waterproof outer cover. It consists of a long-lasting PEX carrier pipe or pipes surrounded by thick insulation layers, all contained in a unique double-wall outer casing for maximum protection. The flexibility and light weight of R-flex makes it far easier to install than rigid piping systems. Superior protection Surrounding the inner PEX carrier pipe are several layers of cross-linked polyethylene foam with a closed cellular structure. This unique design provides R-flex with a low water vapor absorption, enhanced R-value insulation, and an excellent resistance to extreme temperatures. Most importantly, R-flex is able to maintain these insulation properties over time.
