Knuckle Joint – Torque Thru’
The WellEnTech Knuckle Joint provides flexibility within a tool string while providing a large thru’ bore and pressure integrity. The Knuckle is designed to provide an angular deflection along the tools axis of 15° (30° included) while simultaneously being rotationally locked, making it ideal for operations where torque transmission is required.

Operation
The Knuckle joint is ideal for operations where tight dog legs are encountered or flexibility is required in a tool string. The precision turned sphere provides a smooth, angular deflection and a retained seal provides pressure integrity. It is made up to the tool string like any other cross over or connection. The Ball Bearings provide the means of torque transmission, a full rotation version of this tool is also available, refer to data sheet DS-146a for full details.
