Abstract
Abstract A gasket assembly is provided, in which two annular rings are secured together with a replaceable gasket engaged therebetween, the gasket being of annular configuration and having an annular protruding peripheral portion at its radial outermost edge of Vshape configuration, radial innermost edges of the rings being shaped together define a V-shaped configuration which, when the rings are clamped together, receive the annular V-shaped protrusion of the gasket therebetween, in clamped relation. Each ring is provided with axially bent tabs which are engageable with corresponding tabs of an adjacent ring, the tabs of each pair of rings being complementally configured and being adapted for locking engagement upon pressing the rings together and providing relative rotation between the rings, preferably in a counterclockwise direction. The tabs may take on various forms and may be provided with interlocking means. An asbestos insert or the like may be provided between the two rings to provide compression of the ring assembly.
