A filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing includes an alignment tab disposed on the second housing end. The alignment tab protrudes from the second housing end towards the first housing end. A filter element is positioned within the housing. The filter element includes a first endcap, a second endcap, and filter media positioned between and extending axially between the first endcap and the second endcap. The filter media defines a central opening extending axially therein. An alignment notch is disposed on the second endcap, the alignment notch protruding from the second endcap toward the first endcap.

A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.
