Forsheda 570 Sealing Systems for Connecting Pipes to Manholes

System description

Trelleborg's F-570 is a single lip seal, used for connecting PVC pipes to thin walled PVC, PE or metallic tanks and pipes.

Seal Performance

The F-570 fits around the inside diameter of the access hole. The design of the seal provides excellent sealing performance and significant angular deflection possibilities. F-570 is usually used on smooth wall PVC pipes, but small dimensions (DN 25 to DN 90 mm) may also be used with corrugated hoses in dry networks.

DN 25 to DN 90 mm seals accommodate 2 pipe diameters (see table of dimensions).  The unwanted part of the seal is cut away when used for the larger DN.
