ABSTRACT:
Tubing sections may be coupled together by employing a removable tool that is worm gear driven. The worm gear turns an inner body of the tool which in turn causes rotation of a rotatable coupling fitting. The utilization of a worm driven tool attached to the outer body eliminates the generation of torque which is highly desirable for a user making repairs or installations in outer space.
