Abstract
A low carryover fitting assembly for coupling tubing to a device having a sealing surface is presented. The fitting includes a ferrule having a conical head for seating against the sealing surface. The ferrule has a conical tail. The ferrule has an axial passage that is substantially equal in diameter to the inside diameter of the tubing. The fitting includes a sleeve having a ramped inner surface that is greater in inside diameter towards the forward end of the sleeve and smaller in inside diameter towards a rearward end of the sleeve. The fitting also includes a coupler, such as a coupling nut. The coupler has a front surface that engages the head of the ferrule to push the head against the sealing surface. The nut has an inner ramp or shoulder that engages the sleeve to urge the sleeve towards the head of the ferrule when the coupling nut is tightened. The tubing is compressed between the tail of the ferrule and the tapered section of the sleeve. The tubing is compressed so that it flows to a region between the tail and the ramped inner surface.
