Abstract
An air filter element having an inner metal liner, an outer metal liner, a filter media, an annular end cap, and a composite end cap is provided. The annular end cap is formed over the metal liners such that the metal liners are secured and at least a portion of the filter media is sealed. The composite end cap has an annular plastic insert and a foamed urethane portion. The annular plastic insert is tapered upwardly from an outer insert periphery toward a central aperture. The foamed urethane portion is molded about the annular plastic insert such that the metal liners are secured, at least a portion of the filter media is sealed, and an annular groove is formed on an underside of the composite end cap. The annular groove has a plurality of transverse ribs therein. Urethane flashing occurs proximate the central aperture and/or the outer liner periphery.
