ABSTRACT:
A seal arrangement for a fluid filter assembly which is constructed and arranged to threadedly mount onto an engine block mounting base includes an inner seal and an outer seal. The fluid filter assembly includes an outer shell, a filtering element located within the outer shell and defining therewith an annular clearance space. The fluid filter assembly further includes a nutplate which is anchored to the outer shell and which includes an internally-threaded center aperture for threaded engagement onto the engine block mounting base. The inner seal is positioned between the nutplate and the filtering element and cooperates with the nutplate in order to provide a plurality of flow paths between the inner seal and the nutplate from the engine mounting base to the annular clearance space. The outer seal is positioned between the engine block mounting base and the nutplate and includes a pair of spaced-apart ribs which provide a sealing interface against the engine block mounting base.
