epros®Drain Liner End Seal
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.
Once a cured-in-place liner has been installed there is a certain amount of shrinkage associated with the installation. This is normal, and generally accounted for by the installer in calculating the length of the liner tube/felt required to renew the host pipe and manage the shrinkage effectively.
Periodically, however, the section of host and renewed pipe adjacent to the manhole is not fully lined, cannot be completely sealed and an end seal is required. The epros®DrainLinerEndSeals assure the end of the liner is fully sealed and will not allow infiltration or exfiltration, or root intrusion into the pipe at the sealed end.
Prevents infiltration between Liner and Host Pipe
epros®DrainLinerEndSeals 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 Drain Liner End Seal utilizes the patented Slotted Band® to provide maximum 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.
Patented Slotted Band®
The patented Slotted Band is constructed from a single piece of Stainless Steel (EN 1.4307) precisely rolled to match the diameter of the CIPP liner. The unique shape of the Slotted Band provides the maximium 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.
