Hydraulic Release Running Tool, Liner Setting Tool, connects to the SS-HR Setting Sleeve, or a Liner Top Packer with HR profile, and provides a means to carry a liner down hole, set a liner hanger and release from the liner prior to or, if desired, after cementing.

The primary releasing mechanism is hydraulic with an emergency mechanical back-up release system. This tool carries the weight of the liner on a fully supported collet assembly with no threads that could back off and drop the liner while running in the hole. High torque ratings of the HR system allow aggressive rotation if required to work a liner to bottom.
