Abstract: A device for adapting a cover for an existing air filter assembly to seal an end portion of a replacement cylindrical air filter having a round cross-sectional shape is disclosed. The cover has a plate with a radially inner convex guide separated from a radially outer convex guide by a concave receiver, a tightening member connected to the plate, and a catch having a first end movably connected to the tightening member, and the catch having a second end configured to engage a keeper, the tightening member adjustable to vary a distance between the catch and the plate. An adaptor is attachable to the plate of the cover. The adaptor has a first side for engagement with the plate and an opposing second side for engagement with an end portion of a cylindrical filter. The first side has a sealing surface extending radially inwardly from a peripheral edge.

Abstract: A filter element (10) is disclosed having a integral clamp (100) thereon. The adjustable clamp (100) is held against a sleeve (90) by attached tabs (91). The sleeve (90) covers a collar (70) with a plurality of fingers (72) thereon. A high head, e.g., the apex, formed by a bead (80) in the fingers (72) permits better sealing between the filter (10) and the filter's support housing.
