Abstract
A connection is provided whereby a first tube, which may be bent into an elbow, has at least one end flow drilled. During the flow drilling process the first end is shortened, reduced in thickness, and most importantly, the inner diameter is increased to accept a second tube. Before connecting the second tube, the first end is preferably tapped with threads which can receive a nut and the nut captures an end of the second tube, preferably entrapping one of at least one bead and a ferrel to provide a connection.
