A seal between the opposing surfaces of two joined members, wherein at least one of the surfaces is disposed about a bore or cavity. A salient portion (edge or bead) is formed on at least one of the surfaces and around the bore or cavity, and a gasket of resilient material is disposed between the surfaces to overlay the salient portion. The portions of the opposing surfaces other than the salient portion are substantially planar, and the gasket extends across the salient portion. Each salient portion is preferably formed by its opposing surface being disposed at an incline to an apex and the gasket is configured to have a thickness such that some extending portion thereof aside the salient portion is subjected to compression, of lesser degree than that applied by being at the salient portion. Continual forces are applied through a spring means to clamp the members across the gasket in one embodiment, while the gasket is compressed within the bore or cavity to preclude voids at the sealing interface in another embodiment.
