A method and apparatus used for connecting adjoining conduit segments in oil and gas well operations is disclosed. The apparatus and method discloses use of a receptacle assembly attached to one conduit segment and stinger assembly attached to a second conduit segment. A rotatable wheeled hub threadably joins the stinger assembly to the receptacle assembly. The conduit connection ends of the stinger assembly and the receptacle assembly may be configured to accommodate a variety of common types of conduit connections such as Chiksan, hose, pipe, tubing, casing, flanges, hubs and other conduits for conveying media.
