Abstract
Gasket for sealing between flanges in a pressurized fluid system. A central opening is disposed within an inner periphery of the gasket, the inner periphery being curved toward the central opening. Fluid pressure on the inner periphery is reacted by hoop tension in the gasket. The outer periphery of the gasket has concave segments between fastener holes so the area of the gasket is substantially less than the area of the flanges. In this manner, the clamping pressure exerted by the flanges on the gasket is increased.
