    Abstract: A fitting includes first and second fitting components adapted to be joined on a conduit to a first relative axial position to effect a seal between the conduit and a sealing element, sealing the conduit from a non-wetted fitting interior volume at least partially defined by the first and second fitting components. When the first and second fitting components are joined to the first relative axial position, first and second annular surfaces of the fitting axially engage, resulting in resistance to additional axial stroke of the first and second fitting components. At least one of the first and second annular surfaces includes a recess extending from an inner diameter to an outer diameter of the corresponding annular surface, and defining a leak detection port in fluid communication with the fitting interior volume when the first annular surface is in engagement with the second annular surface.

    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.
