Designed to seal the raw end of a relined/renewed pipe which has been lined with a cured in place product, and prevent infiltration or exfiltration into or from the end of the liner.
Prevents infiltration between Liner and Host Pipe
Trelleborg Liner End Seals stop leaking at the manhole to liner connection by bridging the joint with a flexible rubber seal and compressing the rubber seal against the inside diameter of the pipe on either side of the joint with expansion bands.
Design and Function
The Liner End Seal utilizes the patented Slotted Band to provide the maiximum sealing force with a minimum reduction in pipe diameter. This unique design captures the rubber and compresses it against the host pipe and new CIPP liner creating a permanent mechanical seal.
- Manufactured from EPDM Rubber and Stainless Steel to withstand the harsh sanitary sewer environment
- Complies with material property requirements of ASTM C923
- Quick and easy to install
- Eliminates Infiltration/Exfiltration between Liner and Host Pipe.
Patented Slotted Band®
The patented Slotted Band is constructed from a single piece of Stainless Steel (EN1.4307) precisely rolled to match the diameter of the CIPP liner. The unique shape of the Slotted Band provides the maximum amount of strength and sealing force with the least possible thickness. The band is then expanded using a hydraulic expansion tool. As the band expands the integral latching mechanism progresses from slot to slot, positively locking on each one until the next one is reached. There is an audible click created by the spring/rubber interaction as the band is expanded into place.
