Leak-Free Stuffing Box

A sealing solution that minimizes environmental impact, requires minimal maintenance, and provides leak-free operation in the harshest environments for extended periods of time

Have a question? Contact us.

Our leak-free stuffing boxes ensure complete sealing by providing simultaneous dynamic and static sealing with the added protection of a gas exclusion system and optional leak monitoring/indicating equipment. Produced fluids are routed down the flowline, keeping them off the wellhead and, most importantly, off the ground.

Dynamic sealing

This stuffing box system provides critical environmental protection while guarding the stuffing boxes' internal components from contamination. It is available in two configurations: dual-mechanical seal (DMS) and triple-lip seal (TLS).

Static sealing

A Z-Seal packing arrangement maintains a continuous seal between the polished rod and the stuffing box shaft as they rotate in unison.

Gas exclusion

An integrated oil-filled standpipe and roto glyd ring are fitted to each leak-free stuffing box to prevent gas ingress.

Features/Benefits

Twin-bearing arrangement that isolates the seal package from polished rod side loading and misalignment
Available as integral (direct connection to the drive head) or retrofit (using a booth)
Easy fitting of the cartridge-style seal carrier stack
Seal package is mechanically locked in the housing cavity for proper performance
Positive keyed drive of seal sleeve
Internal standpipe added to divert produced gases away from dynamic sealing faces
