Abstract
A coupling for connecting two tubular members. The coupling being comprised of two hubs with annular flanges having axially outwardly facing frustoconical surfaces. The hubs have axially inwardly facing tapered faces, the radially innermost point of said tapered faces being perpendicular to the axis of the tubular members. The tapered faces of the hubs have registering seal rings grooves formed therein, a seal ring being positioned in the seal ring grooves. The hubs are held together by a pair of outer clamps having inner surfaces shaped for engaging the axially outwardly facing frustoconical surfaces of the hubs. Compression of the clamps toward one another forces the inwardly facing tapered surfaces toward one another and brings them into engagement. The engagement of the tapered surfaces forms a primary metal-to-metal seal. The seal ring within the seal ring groove forms a secondary metal-to-metal seal.
