FFKuS-EM-F Highspeed is a medium-sized corrugated plastic pipe made of PVC, with a highly slippery inner layer, plastic coating, non-flame-spreading, in blue. This corrugated plastic pipe is used for concrete and cavity wall installations as well as at low temperatures in the ground. The advantage is the highly slippery inner layer. This allows cables and lines to be pulled in over longer distances without any problems. VDE 0605 DIN EN 61386-22 Minimum compressive strength: 750N/5cm
