A method of injection molding a gasket, comprising: injecting hot, flowable organic polymeric gasket material into a cavity of a mold through an ingate to form a longitudinally extending body of the gasket having laterally opposite side surfaces and a plurality of retaining nubs spaced longitudinally from one other and projecting laterally outwardly from the opposite side surfaces of the body; forming at least one longitudinally extending ingate rib of gasket material projecting laterally outwardly from at least one of the opposite side surfaces on the body and bridging at least two adjacent retaining nubs defining bridged retaining nubs and non-bridged retaining nubs, and allowing the gasket material to cool, opening and removing the gasket from the mold, and trimming the ingate rib to form a free trimmed edge of the ingate rib that projects from the body no further than the non-bridged retaining nubs.
