Grizzly Environmental Stuffing Box (GESB) wellhead accessory gives complete control over contamination from worn packing and broken polished rods while it lubricates the polished rod.

If a polished rod breaks and the rod string falls through the GESB, the stuffing box and B.O.P., and you are protected. The spring loaded valve flapper snaps shut keeping the well contained.


The GESB can be used with a pressure gauge, sight gauge, or other leak indicator to provide notification that your packing is wore. Lubricating the polished rod allows the packing to last longer therefore reducing the amount of time spent changing packing over the life of the well.
