Claim:
1. A ring-shaped gasket for sealingly joining opposed fluid conduit ports, the gasket comprising: a gasket body having a radial outer surface, a first axial end surface, and a second axial end surface, the gasket body being pierced through by a hole creating a fluid pathway and defining a radial inner surface, at least one of the first and second axial end surfaces having a stress concentration feature, the stress concentration feature being formed in the gasket body to define a lip on the at least one of the first and second axial end surfaces, the lip projecting axially outward beyond the at least one of the first and second axial end surfaces and including a sealing surface adjacent a protective ridge, the lip having a radial undercut formed by the stress concentration feature, a bottom portion of the radial undercut extending radially and axially inward of at least a portion of the lip, and the lip being constructed and arranged to plastically deform in response to the sealing surface contacting a face surface of a corresponding fluid conduit port.
