    摘要: The air filter element may include an inner metal liner, an outer metal liner, a filter media, an annular end cap, and a composite end cap 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 a foamed urethane portion and a rigid urethane portion. The foamed urethane portion, which has a central aperture and stand-off apertures, is molded about the central aperture and the stand-off apertures such that the metal liners are secured, at least a portion of the filter media is sealed, and urethane flashing occurs proximate one or more of the central aperture and an outer liner periphery. The rigid urethane portion is molded over the foamed urethane portion such that the stand-off apertures are filled, blocked, and/or sealed.
