Abstract
An improved diaphragm for use with a gasket to prevent leakage of a pressurized fluid. The diaphragm has an internal groove which uses strong spring back and the pressure of the fluid to increase the gasket seating load, thereby providing a self-energizing seal which can accommodate changes in gasket load due to changes in fluid pressure. In one embodiment, a ring is shrink-fit or press-fit about the outer side edge of the diaphragm which improves strength and reduces the material cost.
