ABSTRACT:
A filter of the throw away spin-on type having a housing body with a closed end and an open end, a filter element mounted within said body, a cover plate secured to and closing said open end, a gasket retainer secured to the end closure cover plate, fluid input and output apertures provided in both the cover plate and the gasket retainer, the gasket retainer having a recessed pocket extending circumferentially around the fluid flow openings, inwardly of the outer circumference of the gasket retainer, said gasket pocket having a base at a specified angle relative to the surface plane of the cover plate, and a resilient flexible gasket member of special shape retained by the gasket retainer pocket. The specially configured sealing gasket member is preferably of rhomboid shape and thus a cross section thereof forms a parallelogram with oblique angles and opposite sides equal. The top and bottom surfaces of the sealing gasket form an angle of approximately 10.degree. with the plane of the cover plate and the surface to be sealed, while the inner and outer sides of the gasket member are approximately normal (90.degree.) to the surface to be sealed. A gasket member of trapezoid configuration in cross section may be used in a modified embodiment.
