Abstract
A fitting subassembly includes a threaded fitting nut that can be joined with a threaded fitting body to form a fitting assembly. The fitting nut includes a radial drive surface and an interior wall defining a socket. A back ferrule is disposed entirely in the socket and includes a driven surface adjacent to the drive surface, and a front ferrule is at least partially disposed in the socket. A retaining member retains the front and back ferrules with the fitting nut as a subassembly prior to the fitting nut being assembled with a threaded fitting body. The retaining member applies a retaining force that is limited to permit removal of the front ferrule and the back ferrule from the fitting nut by exposure to a force applying environment.
