Pump packing, for liquid ends of direct acting and power pumps, is used to provide a seal around a rod, plunger, or piston. For a piston, the packing is contained in a groove in the piston, and moves with the piston. For a rod or plunger, the packing is stationary and is contained by a stuffing box.
PPP stocks and sources most plunger pump packing and brass - lantern rings, throat bushings, junk rings, followers, washers and glands.
