A spin-on filter cartridge (20) comprising a cannister (21), a filter element (22), and an adaptor-mounting plate (24) positioned within the cannister (21) between its open end and the filter element (22). The adaptor-mounting plate (24) has a scooped-ramped inner perimeter that allows non-threaded engagement with an adaptor (60). To install the filter cartridge (20) onto a threaded mounting stud (61), the cartridge (20) is rotated (, 'spun') relative to the stud (61). |
