GPGS - Landing Sleeve

The SENTINEL GPGS is a threaded PTFE landing sleeve designed for direct installation into the tubing hanger of a producing well. The landing sleeve is precision‑sized to match the tubing hanger pick‑up threads and align with the tubing string suspended below the wellhead. We have recently upgraded the original material to glass-filled PTFE to provide better durability, longer service life, and greater cost savings for the customer.

The GPGS is engineered to receive the GPGI insert bushing, and when the two components are mated together, they provide solid, centralized support for the polished rod. This added support helps reduce side loading on the stuffing box, resulting in extended stuffing box packing life and increased polished rod longevity.
