A seal for a spin-on filter of the type including an outer housing having a closed end and an open end, an end cover provided in the open end and a filter element disposed within the housing, the filter being adapted to be attached by screw threads to a mounting plate. The seal includes an annular gasket disposed within an annular seating recess formed in the end cover, the gasket having a circumferential groove formed on the inner face thereof. A portion of the end cover extends into the groove in the gasket to retain the gasket within the recess. The gasket is thus retained within the recess in the end cover but is freely rotatable relative to the end cover as the filter is rotated during installation. The seal requires no face selection, will feed in the lathe cut assembly insertion machines currently in use, will fit most conventional ding type gasket retaining recesses, and has rounded edges to eliminate trapped air.
