Abstract: A filter for a fluid system includes a filter housing, and a filter medium within the filter housing. A filter cap component is coupled to the filter housing and includes a fluid distribution wall having therein a plurality of fluid openings. The filter further includes a seal having an annular central body and a valving skirt contacting an outgoing wall surface of the filter cap component at an anti-drain back sealing location. The valving skirt is deformable away from the outgoing wall surface to permit fluid flow through the fluid distribution wall, and alternately seals against the fluid distribution wall to prevent drain back.

Abstract: A filter assembly for a fluid system such as an oil system for an engine includes a first filter component having a first threaded peripheral surface and a plurality of posts projecting from a radially extending surface. The filter assembly further includes a second filter component including a second threaded peripheral surface and a plurality of detent clips matched to the plurality of posts in number and in angular spacing around the center axis. At least one of, the plurality of posts or the plurality of detent clips, is deformable in a radial direction via relative rotation of the detent clips together about the center axis to click-lock engage the detent clips with the posts.
