A conduit-connector coupling structure, otherwise sometimes known as a clamp-type connector, incorporates plural clamp segments operating to cam together flange members producing the coupling. Clamp segments are employed with connecting attachment means so as to draw together the flange members employed upon the tightening down of the clamp segments relative to each other. The forward flange portions of each of the flange members are provided with recesses mutually accommodating the insertion of a metallic sealing ring. When the flange members are drawn together the sealing ring is held in radial compression. The ring itself is provided with mutually spaced peripheral sealing lands on respective ones of its oppositely tapered sides. The ring is designed so that the recesses separating the lands will essentially maintain their integrity for all radial compressions to the ring which is intended for use solely within the elastic limit and below the yield point of the material of such ring. Thus, should a portion of the seat structure of the flange members become scored or damaged so as to prevent a complete sealing action to take effect as between such flange member and one of the sealing lands of the ring, the remaining lands will still be present to effect the sealing function. An equivalent advantage obtains where it is one of the lands that might have a marred surface; the remaining lands will effect the seal. The recesses between the sealing lands of the sealing ring are provided, additionally, in such sealing ring to distribute the stress pattern and also to enable the ring to remain within the elastic limit of the seal ring material.

In combination, a pair of flange members having mutually-facing faces each provided with a mutually corresponding annular recess, such recesses having inner respective depths and forming inner, annular, inclined, conically straight-sided seal-seat surfaces, a metal, fluid sealing ring having a central interior axis and disposed in said recesses, said sealing ring having oppositely tapered, conically straight-sided opposite annular sides peripherally matching said recesses, each side being provided with vacant relief-groove means defining plural, ring-integral, mutually-spaced annular peripheral sealing lands engaging respective ones of said seal-seat surfaces, and means for advancing said flange members toward each other to compression-load at said sealing lands said sealing ring in radial directions throughout its length perpendicular to its central axis whereby to pressure-seat and thus seal said sealing lands of said ring against said seal-seat surfaces and thereby provide fluid seals thereat.
