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 make 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. Other
insulation types, such as polyurethane (PUR) foam, can crush when the pipe is bent, causing them to lose their insulative properties.

Barrier PEX offers several advantages.

• high resistance to corrosion and pressure at high temperatures
• exceptionally high abrasion resistance
• superb chemical resistance
• proven product with excellent longevity at high temperatures

Flexible, fast, and easy.

R-flex derives a unique benefit from the use of the polyethylene foam insulation and the doublewall outer shell; increased flexibility. This feature provides an advantage when running R-flex between buildings, around trench corners, or through wall penetrations.

The art of simplicity.

Traditional carrier pipes, such as copper or black iron, require installers to cut and install transition fittings to work around an obstacle. With R-flex, installers no longer have to cut pipe and add connecting points. R-flex bends around the obstacle.
