Tubing Ball Seat


The Tubing Ball Seat is used below the running tool when running slotted or screen liners. This tool is run towards the bottom of the liner’s inner string. It is used to set the liner hanger assembly and/or to release the hydraulic release running tool. After pressure setting, the ball and seat are sheared and internally captured. Circulation is then reestablished, and the work string is allowed to drain while pulling out of the hole.


  • Adjustable shear pressures
  • Ball capture with internal bypass feature
  • Tubing threads compatible with inner string
  • Easily field-redressable
  • Compact overall length
