PermaSeal Man-Entry Joint Rehabilitation
Leaking joints in pipeline systems are costly to maintain and result in unsatisfactory performance. PermaSeal is an internal mechanical sealing system for leaking joints and cracks in man-entry pipes.
The seals are made of high quality nitrile-butadiene-rubber for sewage and gas, and EDPM-rubber for portable drinking water. The elastic quality and the expansion fold take over certain axial dislocations at the socket without impairing the sealing function. An optimum sealing of joints is further guaranteed by the two-sided double web.
