Stuffing box

Workover & Intervention

A stuffing box is a sealing device on the top of the lubricator (for slickline) or wellhead (for rod pumps). It uses packing elements (rubber) compressed around the moving wire or rod to prevent well fluids from leaking to the atmosphere.

For slickline, the stuffing box allows the wire to move up and down while maintaining a dynamic seal. It usually includes a sheave wheel to guide the wire from the unit to the well.
