It is a component of a pumping unit. When the pumping unit' s polish rod moves up and down repeatedly, the stuffing box can play a role in sealing so as to prevent the liquid in the oil well flom leaking. However, there can be friction, called "eccentric wear" , between the polish rod and stuffing box for some reason during their relative movements.
