ABSTRACT:
A device for coupling two pipe sections together such that each of the connected pipe sections may swivel relative to the other. Each of the pipe sections have uniform and equal exterior diameters into which circumferential grooves, preferably a pair, are formed. The pipe sections are held together by a split clamp having inwardly extending ribs which mate with the grooves formed in the pipe sections. The size of the pipe section grooves and the split clamp ribs provide an annular space in each groove inwardly of the split clamp rib in which resides a compressible bearing ring. A washer ring separates and seals between the ends of the two pipe sections. The resulting pipe coupling is largely symmetrical about both its radial and axial centerpoint planes. Under pressure, the load is equalized over the multiple bearing rings.
