ABSTRACT:
The invention is a sealing apparatus and method of providing a seal for polished rods in oil and gas well applications. The sealing apparatus has a fluid responsive gland which forms a seal between the inner surface of a unitized housing body and a polished rod to effect a seal of fluids within a well. The fluid responsive gland comprises packing rings of supple and rigid materials, in alternating configurations to achieve a seal. The sealing apparatus is self-aligning, and the packing rings reside in a continuous and uninterrupted zone. The packing rings may be replaced without removing the sealing apparatus from the polished rod. The sealing apparatus may be aligned without external alignment apparatus or adjustment.
