Kabuflex® R plus type 450 is a flexible cable protection pipe made of PE, in black, halogen-free, in a composite construction with an optimized green inner skin for quick cable insertion. Another feature is the improved stability through the use of high-quality materials. It is corrugated on the outside and has a transparent double plug-in sleeve attached to one side (sand-tight). This cable protection pipe is used, for example, under streets, squares, in the ground, etc. Special double plug-in sleeves connect the pipes in a sand-tight (SD) manner; a profile sealing ring creates a watertight connection (WD) up to 0.5 bar. The Kabuflex® R plus type 450 is supplied with a pull-in cord. The advantage lies in the high compressive strength.0605, DIN EN 61386-24, compressive stress type 450, impact resistance normal, classification code N450
