Wave seal for filter element

Abstract:

A filter element includes a filter media having opposite first and second faces, and an outer face extending in a longitudinal direction perpendicular from the first face to the second face. An undulating sealing element is directly bonded to the outer face at a location closer to and offset from the first face. The undulations of the sealing element define an offset region of the outer face of the filter media from the first face, the offset region being defined by an amplitude of the undulations. The filter element may be incorporated into a filter assembly including the filter element enclosed by a filter housing. The sealing element may be made of urethane and be compressible within a mating groove in the filter housing.
