ABSTRACT:
A coupling assembly for coupling an elongated cylindrical element such as a pipe section or shaft to a second element such as another pipe section or shaft. A shallow circumferential groove is formed on an outer circumferential surface of the cylindrical element at a position spaced a moderate distance from the end at which the coupling is to be made. At least one split ring mounted in the groove and has an outer circumferential portion tapering inward from a center line toward the back of the ring. A generally hollow cylindrical housing is mounted over the split ring and has a tapered inner surface portion contacting at least a portion of the tapering outer surface of the split ring. A fastening arrangement draws the housing toward the other element to force the tapered inner surface portion of the housing into contact with at least a portion of the tapering outer surface portion of the split ring. This presses the split ring onto the cylindrical element so that the housing and the split ring tightly couple the cylindrical element to the second element. Two housings and two split rings are used to couple two cylindrical elements together. A sealing arrangement is provided within the housing in the case that a pipe section is being coupled to a flange or another pipe section to provide a fluid-tight seal at the joint.
