It is designed for disconnection of the tubing string in case of complications with tripping the downhole equipment in and out.


  • flowing and gaslift well operation;
  • well pumping;
  • in packer downhole BHAs during well operations or downhole procedures;
  • used with P-EGM packer.


  • in case of complications it enables to disconnect downhole equipment and tubing string in the MRG installation point;
  • reduces the risk of serious complications during well pumping with ESP units, with high scale build-up;
  • the sleeve contains a spline joint that provides torque transmission via the tubing string to the equipment installed below.


  • it has movable cams to connect the case and the rod;
  • it has a movable bushing and a ball to disconnect the case and the rod.
