Internal Dimple Connector

The high tensile and torque loads of the internal dimple connector make application to coil easy, convenient, and positive.


Unlike existing slip connectors, the internal slip connector does not rely on grub screws to transmit torque from the tool string through to the coiled tubing.

This feature is provided through a unique nonrotational slip arrangement providing high bidirectional torque resistance. The slip is positively engaged into the bottom sub via drive teeth, therefore transmitting any rotational torque from the tool string directly to the pipe.

The basic installation to the coiled tubing does not require any specialized tooling or makeup torque. The connector is simply fitted to the pipe and an overpull is taken to test and set the connector.

The internal slip connector also has only four main components and includes an enclosed locknut feature to prevent the connector from being jarred free from the pipe.

Both internal and external versions of the slip connector feature an interchangeable service connection sub, allowing the operator to easily change from one thread connection to another.
