Disclosed is a small space-saving two-part coupling system for attaching threaded pipes which is particularly suited for use in replacing broken valves, pipes or parts in existing plumbing systems where little space is available. The invention includes a pair of nuts with male extensions located thereon, each nut having a helically threaded axial bore therethrough, and exterior helical threads on the male extension. The bore of the first nut has R.H. threads, and the male extension of the first nut has L.H. threads. The bore of the second nut has L.H. threads, and the male extension of the second nut has R.H. threads. The nuts are designed to be coupled to each other using the L.H. threads, and coupled to an existing pipe system using the R.H. threads.
