Abstract
Fluid connector for connecting a first fluid-bearing conduit in a capillary tube to a second fluid-bearing conduit in a receiver. An internal fitting assembly includes an internal fitting body, a body cavity for receiving a ferrule and a self-compensating nut, the ferrule and self-compensating nut being locatable on the capillary tube, and an internal ferrule seat located on a portion of the body cavity, against which a tapered portion of the ferrule is applied to so as to obtain a first fluid-tight seal between the capillary tube, the ferrule, and the ferrule seat. The forward end of the internal fitting body includes a nose cone, having thereon an annular projection, a neck portion which connects the nose cone to the remainder of the internal fitting body, and an annular seal located on the neck portion, wherein the annular projection defines a first frustoconical segment and the annular seal includes a second frustoconical segment, the first and second frustoconical segments being configured to establish a second fluid-tight seal at the receiver port surface as the forward end of the internal fitting body is coaxially aligned with the receiver port and thrust into the receiver cavity.
