Popular Name： Stuffing Box / Sealing Head / Liquid Seal Slickline Control Head
The Stuffing Box is designed to pack-off all size of slickline (solid wireline) up to 0.160”, with safety and convenience.
It is lightweight, compact and simple to operate. Positioned at the uppermost point of the Slickline PCE. The Stuffing Box incorporates a Blowout Plug to automatically shut-in the well pressure in the event of the slickline breaking or being stripped from the Rope Socket. A ball check valve is provided optional to prevent the escape of well fluids in the event of the slickline breaking.
The Slickline Stuffing Box consists of a chamber which contains packing with an external adjustable nut. The slickline passed through the packing and the nut is hydraulically tightened to the point where leakage around the line, caused by well pressure, is reduced to a minimum. A 16” diameter sheave bracket assembly ( or 20” diameter in case of 0.160” wire ) and a male quick union assembly are supplied with the Stuffing Box as standard.
The sealing parts of the Stuffing Box should be replaced while the slickline size changed. And a Glycol Injection port could be added if required.
