Abstract: A filter cartridge in accordance with the present disclosure has a longitudinal axis and comprises a housing, a filter element, and a collar. The housing has a generally cylindrical sidewall and defines an open first end, an axially opposite second end, and a flange projecting radially away from the axis at the first end. The filter element has a ring of filter media circumscribing the axis and extending between first and second end caps. The first end cap has a generally cylindrical wall extending axially between first and second peripheral rims. The wall defines first and second seal glands adjacent the first and second rims which receive first and second seal members, respectively. A ledge projects radially outwardly from the cylindrical wall. The collar has an annular sidewall having a shoulder projecting from an inner surface. The ledge and the shoulder radially overlap and retain the flange therebetween.

The housing has a generally cylindrical sidewall and defines an open first end, an axially opposite second end, and a flange projecting radially away from the axis at the first end. The filter element has a ring of filter media circumscribing the axis and extending between first and second end caps. A ledge projects radially from an inner surface of the second collar. The second collar has an annular sidewall having a shoulder projecting from an inner surface. The ledge and the shoulder radially overlap to retain the flange. The first collar may define axially-oriented grooves configured to receive corresponding radial projections of the first end cap, axially securing the filter element within the housing.
