Abstract
A one-piece plastic injection molded filter housing has a first end and a second open end. An injection molded end plate member includes a circumferential annular flange, and an inward annular projection. Opposing, one-piece plastic upper and lower end caps include spaced flanges to receive the respective ends of a filter media therebetween. The upper end cap also includes an upper annular projection. The upper end cap is mechanically, removably connected to the end plate member via corresponding threads or a protuberance/recess interference fit combination. The end plate member is fixedly connected to the housing via a rib that fits into a recess on the housing via an interference fit, or by spin welding. The method for manufacturing the filter includes the following steps: connecting a plastic upper end cap to the media to form a media element; removably, mechanically connecting the upper end cap to the end plate member; and fixedly connecting the end plate member to the second end of the housing.
