ABSTRACT:
The invention disclosed herein includes a reducer coupling, a positioner tool for connecting the coupling to a conduit section, and a nut for securing the positioner tool to the coupling. The reducer coupling is useful in various operations, such as some oil field operations in which it is used to connect a smaller conduit (delivery line) into a larger conduit (production casing). In practice, the positioner tool is secured to the reducer coupling and the coupling is moved into its hook-up position above the production casing, by attaching a rig to the positioner tool. The coupling can then be threaded into the casing by turning the positioner tool with a wrench, or similar tool.
