摘要： A filter cartridge that includes a canister configured to hold a filter element. The canister has a canister body with an open end and an end closure. The end closure has a central annular element locating feature, and an annular frame portion circumscribing the central annular element locating feature. The canister body and end closure have cooperating geometry for retaining the end closure to the open end of the canister. The cooperating geometry includes an axial retention mechanism for maintaining an attachment between the canister and the end closure. The axial retention mechanism is configured to maintain the attachment solely via mechanical interference.
