ABSTRACT:
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 oppositely tapered at opposite sides and includes at least one and conceiveably multiple non-metallic seals hereinafter referred to as softseals, which are mounted on a primary ring member. The primary ring member thus includes suitable recesses for accommodating such softseals at its opposite recessed sides. The ring member itself will be metallic and at least portions of its upper surfaces will serve as to control surfaces for limiting compression of the softseals to predetermined amounts. The fluid-coupling seal structure in this invention is intended to accommodate structures where sealing pressures are relatively low, i.e., do not exceed 10,000 psi.
