A packing nut which when retrofitted to or assembled into a stuffing box and hydraulically or manually actuated applies force to packing in the stuffing box, compressing the packing to seal on stationary wireline or pump rods or to wipe or seal on moving wireline or rods passing through a hole in a piston rod on which there is an operating piston in the packing nut body. The piston rod may be rotated to adjust its length for packing contact, and desired packing compression may be maintained by further rod rotation if pressured fluid is not available for hydraulic actuation. A connection for a remotely pressured fluid conduit is provided on the packing nut housing to deliver actuating fluid to the operating piston.
