Abstract
One aspect of the disclosure provides a filter element including a first end cap, a second end cap, a ring of filter media and an annular seal. The first end cap defines a cylindrical collar that circumscribes a first central opening and includes a substantially planar first outer surface that extends radially outward from the cylindrical collar to an outer peripheral edge. The second end cap defines a second central opening substantially coaxial with the first central opening. The ring of filter media is disposed between the first end cap and the second end cap, and circumscribes a central cavity in fluid communication with the first central opening and the second central opening. The annular seal is disposed upon the first outer surface of the first end cap and around the cylindrical collar. The annular seal extends axially way from the first outer surface.
