Abstract
A stuffing box support assembly is configured to be positioned between a production pumping tree and a stuffing box of a wellhead. In use, the support assembly functions like a joint between the wellhead production tree and the stuffing box. The support assembly is configured such that it could tilt or move laterally to maintain a coaxial relationship between the stuffing box and a polished rod extending therethrough. This alignment between the stuffing box and the polished rod reduces wear and tear of the stuffing box packing.
