L-Lock-P™ Liner End Seal is a rubber liner end seal with stainless steel expansion bands, designed to keep the liner firmly in place.
Available in a range of diameters from 6 to 96 inches, the seal has a ribbed structure at both ends that, when compressed by the steel bands, provides a watertight seal.
L-Lock-P™ Liner End Seals prevents infiltration/exfiltration by bridging the interface between liner end and host pipe with a flexible rubber seal and compressing the rubber seal against the inside diameter of the pipe on either side with expansion bands.
The compressive force on either side of the interface point is the result of increasing the effective diameter of the stainless-steel expansion bands.
The flexible rubber seal is composed of high tensile strength EPDM rubber 70 Shore A.
