Abstract
A tube fitting for sealing an end of a tube uses a notch formed in the exterior surface of the tube as a sealing seat. An internally threaded body is configured to receive an externally threaded end of a nut, while the body and the nut are mounted in a surrounding relationship to the tube end. A ferrule mounted between the nut and the tube is forced to plastically deform and move into the notch to thereby seal the tube end.
