ABSTRACT:
An oilfield stuffing box 10 employs mating flange plates 15, 16 with bolt holes appreciably larger in diameter than the bolts employed to hold the flange plates together, thereby permitting lateral displacement between the two flange plates. The lateral adjustment permits the tubular stuffing box section 13 carried centrally on the upper plate 15 to be centrally positioned about a polished rod 12 extending between the two flanges. The lower plate 15 is preferably integral with a well head section 14, and is also provided with the large diameter bolt holes to double the range of permitted lateral adjustment. The relative size of the bolts, bolt holes, polished rod diameter and well head diameter are selected for optimum lateral adjustment with a minimum practical hole-to-bolt size differential. A static seal 22 between the two mating flange plates provides a leak-proof seal at any of the different lateral positions between the two flanged sections 13, 14.
