Torque-Thru Knuckle Joint

Achieve additional flexibility when running highly deviated boreholes with our torque-thru knuckle joint.

The torque-thru knuckle joint provides additional flexibility to the tool string when incorporated between the jars and the manipulation tool. This flexibility is often necessary when running the tool-restricted and/or highly deviated boreholes. The torque-thru knuckle joint can be used when rotation of the tool string is not required, which makes it ideal for coiled tubing drilling applications.

The knuckle joint provides a full 15° angular deviation and internal pressure sealing throughout the full deviation of the tool. The ball and socket of the knuckle have a key that prevents rotation but still allows full angular movement.

The full flow-through bore also allows the use of flow-activated tools below the knuckle joint.

Multiple coiled tubing torque-thru knuckle joints can be incorporated in particularly long tool strings.

When ordering torque-thru knuckle joints, please specify size and thread connection.
