R-flex Insulated Piping System

R-flex is a flexible pre-insulated PEX with a corrugated, double-wall HDPE cover suitable for direct burial. R-flex is manufactured in accordance with DIN 16892/16893, with a DIN 4726 oxygen barrier.

Uses:

• Hydronic heating
• Hydronic snow melting
• District heating
• Commercial and process piping
• Geothermal
• Agricultural piping
• Biomass heat sources
• Wood-fired boilers
• Solar
• Cooling towers & chilled water systems

Note: A cut charge will be incurred with custom cut lengths. Cut Charge Standard is for cuts in 25 foot increments (i.e. 25', 75', 150'). Cut Charge Non-Standard is for any other length increment,(i.e. 80', 105', 170').
