ABSTRACT:
The internally threaded connector device (10a) is a thin-walled, internally threaded tube. A relatively short portion of the device includes a polygonal wrench gripping flange area. The device (10a) is installed on an existing short length of externally threaded stud (BS). Another length of externally threaded stud (12) is installed in the internally threaded connector (10a) so that the second externally threaded stud (12) extends beyond the face of a secured component, such as a flange (F). In an exemplary embodiment, a conventional nut (N) or the like is installed on the end of the second externally threaded stud (12) to secure a flange (F) and associated gasket (G) and pipe (P) to a manifold assembly (M).
