Abstract
Seals for filter elements having filter packs with seals around the periphery thereof adjacent to one of the faces are produced by injection molding the seal onto the filter pack using an ethylene-propyleneterpolymer (EPDM) thermoplastic material. Preferably, the thermoplastic material is embedded in polypropylene particles. The resulting seal has a contact portion which bends and/or compresses upon being engaged by a lid of a filter housing as the lid closes.
