Abstract:
A ring-shaped gasket for making high-purity fluid pathway connections between opposing fluid delivery apparatus elements having at least one simple flat surface in contact with the gasket. The face of at least one apparatus element typically has a circular counterbore depression to receive the gasket, but is not required. The gasket has a body, pierced through by a hole creating a fluid pathway and defining a radial inner surface, and additionally having a radial outer surface, a first axial end surface and a second axial end surface. At least one of the first and second axial end surfaces has a stress concentration feature radially adjacent to a gasket sealing region, the sealing region constructed to be in contact with a face surface of a corresponding fluid conduit port. The stress concentration feature may be a groove or a plurality of cavities disposed adjacent the gasket axial end surface sealing region.

Claim (Index 1):
A ring-shaped gasket for sealingly joining opposed fluid conduit ports, the gasket comprising:\n 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; wherein the first axial end surface has a stress concentration feature formed in the gasket body to define a lip on the first axial end surface, the lip projecting axially outward beyond the first axial end surface and including a sealing surface adjacent a protective ridge, the stress concentration feature comprising an inner wall adjacent the lip, a first surface adjacent the first axial end surface and radially outward of the inner wall where the inner wall is not parallel with the first surface, and a radial undercut formed by the stress concentration feature, where a bottom portion of the radial undercut extends radially and axially inward of at least a portion of the lip, the lip being constructed and arranged to plastically deform in response to the sealing surface contacting a face surface of a first fluid conduit port.
