ABSTRACT:
In plunger-type pumps a packing assembly is installed around the plunger to prevent fluid from leaking past the moving plunger. The packing assembly includes male and female adaptor rings, which are in face-to-face contact with the packing rings, but provide only a "sloppy" fit. The practice of this invention involves shaping the adaptor ring faces to conform precisely to the shape of the packing ring faces against which they are seated.
