Abstract

A conduit coupling assembly for connecting the end portions of a pair of lengths of conduit in coaxial relationship. The end portions of the lengths have external threads of the same size. The coupling assembly includes an annular outer coupling member and an annular inner coupling member for reception by the outer coupling member. The outer coupling member has a first end including an internal screw thread sized for threading onto the end portion of one of the conduits. This outer member also includes a second end including an outer wall defining a cavity with the outer wall having at least one threaded aperture therethrough opening onto the cavity. The inner coupling member includes a first end and an internal screw thread sized for threading onto the end portion of the other of the conduits. The inner coupling member also has a second end sized for reception in the cavity with this inner coupling member second end having a peripheral groove on its outer surface which can be aligned with the threaded aperture. Upon reception of the inner coupling member second end in the cavity, the members can be joined by tightening a set screw located in the aperture so that the screw extends into the groove. Methods of using the coupling assembly of the present invention are also disclosed.
