Flow-Activated GS Type Running/Pulling Tool

Retrieve downhole tools with conventional internal fish necks with our flow-activated GS-type running/pulling tool.


The flow-activated GS-type running/pulling tool is designed to run and retrieve downhole tools with conventional internal fish necks. The latching mechanism is a robust dog/core design that releases positively from the internal fish neck when a hydraulic differential is applied to the tool. The tool does not require shear pins or drop balls because the differential required to activate the tool is provided by circulation through a choke insert in the core.

Flow-activated GS-type running/pulling tools are available for all standard internal fish-neck sizes. When ordering flow-activated GS-type running/pulling tools, please specify size and thread connection.
