The LiMAR® Flo-Release GS Pulling Tool is designed for the setting and retrieval of items with “Otis” type internal fish neck profiles.

The GS is operated by setting down weight to
engage the internal fish neck. If the device cannot be recovered the Flo-Release GS can be released by setting down weight and increasing the coil flow rate to activate the core piston and allow the pulling tool to disengage from the external fish neck.
