Tool for automating tube nut assemblies provides for easy, direct-straight-forward and direct-reverse movements on and off hex nuts. Mounting on a slide rail, actuation causes the tool to immediately slide forward, engaging the tube nut. Then the driver quickly runs down the threads and sets final end torque with accuracy and precision. Instantly, the tool retracts, making it ready for the next assembly.

A combination of a number of valves commonly used in pneumatic load-holding circuits help reduce costs and simplify circuit design. Load-holding circuits may contain a pilot-operated check with a flow control at the cylinder. By combining these valves in one block, extra fittings, tubing, and installation time are reduced, simplifying circuit design and removing potential leakage points. Manual release and lockout are also available for slowly releasing trapped air without having to remove a fitting, and for protection against accidental release.
