Abstract
A branch connector is provided for coupling a main pipe having a liner disposed therein with a service line and for simultaneously sealing the interface between the edges of the main pipe and the liner. The connector includes an outer hollow housing adapted for coupling to a service saddle, the outer housing having a first aperture for placement adjacent to the outer wall of the main pipe and a second aperture adapted for connection to the service line. An inner sealing assembly is adjustably mountable inside of the housing such that the assembly may be axially extended through the first aperture and into the interior of the main pipe. A lower, outer portion of the sealing assembly bears a seal for secure engagement against the liner and the main pipe, closing the interface therebetween.
