  • Resources Resources

Engineered and manufactured for rugged reliability and reduced maintenance, we’ve manufactured over 2,200 coiled tubing injectors so you can rely on our field-proven designs. 

Whether you are packaging a new, custom-built unit with the HR-6140 model injector or just replacing an existing one, our injectors have the performance and dependability that is required in the toughest oilfield conditions around the world.

Designed to handle 2- to 4½-in. coiled tubing strings, this model is capable of running high-strength large-OD tubing designs with superior slow speed control (inches per minute). The HR-6140 has a 140,000-lb continuous lifting capacity and 70,000-lb continuous snubbing capacity.

The hydraulically timed drive and free-floating traction systems enhance performance and reliability in the field by reducing dynamic loads on the coiled tubing and injector components.
