Abstract
Example embodiments of the present disclosure relate to an assembly for sealing a rigid pipe, a furnace, and a gasket for use in an HVAC fluid conduit. Some embodiments include a furnace with an inducer blower drawing combustion air through the furnace, and the assembly is used to connect one or more flue conduit(s) and an exhaust pipe. In one embodiment, the gasket used in the assembly includes a tubular body, at least a portion of which is engaged along an inner surface of the fluid conduit, a rim extending outwardly from a tubular body end, and two or more ears extending from the rim, wherein the ears are spaced apart from the tubular body and extend in substantially the same direction as the tubular body. The ears further include a first rib located proximate a distal end of the ear.
