Abstract
A method is provided for making an injection-molded support of polymeric material having a cylindrical portion having an axis and an end, an annular groove for a sealing ring located proximate to the end of the cylindrical portion and defined by a base surface, a sealing surface and a ring-retaining surface, the sealing surface being farther from the end of the cylindrical portion than the ring-retaining surface. The base surface, a sealing surface, and either a seat portion for a flange formed in a separate molding step that provides the ring-retaining surface of the groove or the entirety of a flange that provides the ring-retaining surface of the groove are formed by a cavity of a mold part that separates from the support in the direction of the axis of the cylindrical portion.
