Abstract
An adaptor assembly to be fitted onto a service pipe comprising a host pipe lined with a lining pipe is provided. The adaptor assembly includes a body to seal with the host pipe, a bore extending along a longitudinal axis of said body, and a compression element mountable on and displaceable relative to the body. The adaptor assembly includes an axially translatable piston, an annular flange protruding into said bore, and a grip ring disposable between said piston and said flange and having an inner radial surface to grip an outer radial surface of the lining pipe. A slip spacer is disposable between the compression element and the piston to transmit axial load but substantially prevent transmission of torque therebetween. The compression element is moveable to axially displace the piston causing the grip ring to bear against the inclined annular flange and grip radially inwardly against the outer radial surface.
