ABSTRACT:
A guided split packing ring comprising a split in the circumference of the annular body defining a nose at one end and a cavity at the other end for matingly receiving the nose therein. The annular body of the packing ring defines a slightly enlarged outside diameter having an interference between about 0.025 to 0.035 inches when the packing ring is positioned in a hydraulic cylinder so as to urge the ends of the split into sealing engagement.
