ABSTRACT:
Disclosed herein is an improved tube fitting of the swage variety which employs a body part, at least one ferrule designed to slip around a tube, and a nut used to compress the ferrule against the tube and the body part and thereby form a leak-tight connection between the tube and the body part. The nut is divided into two parts which are movably interconnected by a radially flanged tubular portion of one of the nut parts. This flanged tubular portion engages the ferrule and prevents rotation of the ferrule while it is being compressed against the body part by rotation of the other nut part.
