Abstract
A rod packing for stripping oil from a string of sucker rods as they are removed from the oil well, and including a pair of interfitting semicylindrical packing halves joinable to each other at a diametrical plane by pairs of mating protuberances and sockets. An axial bore is formed by mating semicylindrical grooves in the packing halves which are in registry when the packing halves are joined. Opposite ends of the axial bore communicate with frusto-conical recesses centered in the opposed planar ends of the joined semicylindrical packing halves, and each of the packing halves includes a pair of spaced, substantially parallel, chordally extending grooves in one of the planar ends thereof positioned to intersect the respective frusto-conical recess in that planar end, and to receive accumulated liquid therefrom.
