Abstract: A spin-on filter comprises a housing shell, a filter element, a nutplate, and a gasket. The filter element is positionable within the housing shell and comprises a filter media and an endplate. The nutplate is positionable within the housing shell. The gasket comprises a central body and a spring-loaded extension. The spring-loaded extension circumferentially surrounds and extends radially from the central body. The spring-loaded extension is axially flexible between an expanded position and a compressed position. The spring-loaded extension forms and maintains a first seal with the endplate and maintains contact with the nutplate as the spring-loaded extension moves between the expanded position and the compressed position.
