The RMZ Hydraulic Wireline Stuffing Box is used when it is necessary to perform wireline work under well pressure. The sheave assembly allows the line to be guided from the wireline unit and through the Stuffing Box Body. Slickline is passed over the sheave wheel and down through a hydraulic packing stack within the stuffing box body. Upper and lower bushing are provided to ensure that the slickline is guided into the centre of the packing stack.

The hydraulic packing stack can be compressed from a safe distance should the packing leak due to wear.

Internal component that are in contact with the wire are manufactured from brass. A ball check valve is provided to prevent the escape of well fluids in the event of the slickline breaking.
