ABSTRACT:
An oil well pump leakage accumulator and bypass apparatus installable around a polish rod, and which apparatus effectively prevents contamination of the environment when the primary stuffing box in the blow out preventer unit fails. An adjustable stuffing box with a packing gland is exposed on the top of a swage assembly to collect any leaking oil and bypass the oil to a collection pipe emptying an intermediate region or chamber of the swage assembly. The chamber permits the absorption of the blow out of gas and oil resulting from the failure of the primary stuffing box in the blow out preventer unit.
