Abstract

A fitting for use with corrugated stainless steel tubing. The fitting includes a body having a locating sleeve. The locating sleeve aligns the central axis of the body with the central axis of the tubing. A nut, retained on the tubing by split ring washers, is tightened on a threaded end of the body. As the nut is tightened, a taper formed on the body flares the tubing. The flared tubing is compressed between the taper on the body and a beveled section of the split ring washer. This forms a leak proof fitting without the need for separate flaring tools.
