Wefatherm Wefaklim Fiber SDR 11 PP-RCT pipes are manufactured from Polypropylene Random Copolymer for Raised Temperature (PP-RCT). Fiber reinforcement improves dimensional stability and reduces thermal expansion. Pipes feature four blue stripes for easy identification, except for 20–25 mm sizes which do not have stripes.
These 4-meter grey pipes are ideal for:
-
Central heating systems
-
Air-conditioning networks
-
Climate control and commercial plumbing applications
