ABSTRACT:
A method for attaching an elastomeric gasket (12, 70) to a thermoplastic substrate (10) comprises the steps of forming the substrate (10) with a slot (20) and an upstanding projection (22) adjacent the slot (20), deforming the projection (22) into an upper portion of the slot (20) to provide a stake thereby, and molding the elastomeric gasket (12, 70) onto the substrate (10) and into the slot (20). The elastomeric gasket (12, 70) is thereby retained on the substrate (10) by the projection (22) in cooperation with the slot (20). The substrate (10) is preferably made of a nylon material, and the elastomeric gasket (12, 70) is preferably made of an EPDM polymer.
