Patent ID: 8205916

Claim:
A high-pressure fluid conduit, comprising: a first fluid conduit subcomponent having a pin end with an annular groove in the pin end, a second fluid conduit subcomponent having a socket end that receives the pin end and has a complementary second annular groove in a bottom of the socket, the first and second annular grooves having respective annular outer faces that slope inwardly to a planar annular bottom surface of the respective annular grooves; and a metal ring gasket compressed between the respective ends of the first and the second fluid conduit subcomponents, the metal ring gasket deforming elastically, without plastic deformation, to provide an energized high-pressure fluid seal when the first and second fluid conduit subcomponents are drawn together by a nut, the metal ring gasket having a planar top face, a planar bottom face that is parallel to the planar top face, a cylindrical outer face, and an annular sloped surface between each of the planar top and bottom faces and the cylindrical outer face, the metal ring gasket being compressed by contact with only the respective first and second sloped annular outer faces of the respective first and second annular grooves when the first and second fluid conduit subcomponents are drawn together by the nut.
