Tapered compression ring for flared tube applications

The present invention is directed generally to self-locking nut/sleeve assemblies for flared tube applications, and more particularly to a nut/sleeve arrangement which utilizes a tapered compression ring to achieve enhanced loading around the flare fitting. A tapered compression ring for flared tube applications includes a generally ring-shaped body having (a) a gap defining a first end and an opposite second end, (b) a first face, (c) an opposite second face, and (d) a central axis. The first face is tapered at the first end, and the body is twisted so that the first end is offset from the second end along the central axis in a direction away from the first face.
