Hydraulic Stuffing Box isused to seal off around moving or stationary solid wireline while performing wireline work under well pressure. Connected to the top section of the Lubricators, toallow the wireline to be guided in its travel; internal packings which seal off pressure and provide lubricant to the wireline; packing nut to control the hydraulic compression of the packing around wireline to minimize leakage; and a blow out plug at the lower section to provide a seal should the wireline break and be blown out of the packing.
