KNUCKLE JOINTS
The Knuckle Joint, when incorporated between the jars and the manipulation tool, provides additional flexibility in the tool string. The Knuckle Joint allows a full 360° rotation of the tool string and provide a full 15° angular deviation and internal pressure sealing throughout the full rotation of the tool. The ball and socket of the knuckle joint provide the rotation and angular deviation of the tool. Seals in the ball provide the sealing capability.
