Abstract:
1. A filtration sealing system for sealing a filter element in a housing at a mating interface therebetween, said sealing system comprising a keyed said interface, wherein: said filter element and said housing have borders mating with each other at a multi-part gasket therebetween providing said mating interface; said multi-part gasket comprises a first gasket on said filter element, and a second gasket on said housing; said first gasket has a first gasket-engagement surface for engaging said second gasket; said second gasket has a second gasket-engagement surface for engaging said first gasket; said first and second gasket-engagement surfaces engage each other in keyed relation providing said keyed interface; said multi-part gasket extends along an extension direction along a perimeter; said first gasket extends along said extension direction between distally opposite first and second beveled ends tapered along opposing first and second tapers along said extension direction; said second gasket extends along said extension direction between distally opposite third and fourth beveled ends tapered along opposing third and fourth tapers along said extension direction; said first and third beveled ends engage each other in sealed relation; said second and fourth beveled ends engage each other in sealed relation; said perimeter defines a perimeteral plane; fluid to be filtered flows through said filter element in an axial direction normal to said perimeteral plane; said first and third beveled ends taper to reduced axial heights and overlap each other along said extension direction and engage each other in axial alignment along said axial direction; said second and fourth beveled ends taper to reduced axial heights and overlap each other along said extension direction and engage each other in axial alignment along said axial direction.
