Abstract
One embodiment is a unique replaceable filter element. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings.
Claims14
A replaceable filter element comprising:
- an annular, pleated filter media having a first end, a second end, and defining an interior cavity;
- a first endplate coupled to the first end of the filter media, the first endplate including:
- an outer periphery;
- an opening leading to the interior cavity, the opening forming a fluid passage for filtered fluid;
- a sleeve adjacent the opening and extending away from the second end to an end;
- an annular sealing gasket disposed around the sleeve, the sealing gasket being rectangular in cross-section, and is disposed in a space between the sleeve and a first flange that surrounds the sleeve, the annular sealing gasket does not extend beyond the end of the sleeve;
- and a first plurality of legs extending from the outer periphery to leg extremities located outward from the outer periphery;
- each leg includes an upper, radially outward extending section connected to the outer periphery of the first endplate, and an axially depending section that overlaps the filter media and that extends toward the second end;
- the first flange projects from the first endplate in the same direction as the sleeve, and the first endplate further includes a second flange surrounding the first flange and projecting from the first endplate in the same direction as the first flange, and a plurality of circumferentially spaced ribs projecting from the first endplate and extending between the first flange and the second flange;
- and
- a second endplate coupled to the second end of the filter media.
