Abstract: A process for forming a metallic tubular connector of the type having a cylindrical shell which extends circumferentially about a tubular body for joining said tubular connector to a conduit. The process involves using a first forming machine to form a first peripheral bead in a first end portion of a tubular metallic body, having a substantially uniform diameter and wall thickness, reduce the outside diameter of a second end portion, and slope an intermediate surface portion. Then, a second end forming machine tool, carrying a metallic socket, freely receives the tubular body second end portion, contacts the sloped intermediate surface portion, forms a second peripheral bead adjacent the first peripheral bead, while an annular end surface of the socket is compressed and locked between the first and second beads. Further, the tubular body is manufactured from a 5000 series aluminum alloy material.

Abstract: A process of roll forming a tubular metallic body for a fluid connector comprised of first affixing a tubular metallic body of substantially constant diameter in a roll forming machine, then positioning a series of freely rotatable independent tools in a circumferential pattern surrounding the tubular body. The tools are then rotated within a predetermined velocity range and minimal radial contact is applied between the series of tools and the tubular body. This contact forms at least one radial groove in the tubular body, smoothes the outer surface of the tubular body and decreases the outside diameter of a portion of the tubular body for a predetermined distance along its periphery at a constant, uniform rate. Also the proximate end of the decreasing diameter portion is rounded. Further, the metallic tubular body is fabricated from a 5000 series aluminum alloy.

Abstract: A connector for attachment to a tubular conduit, having a generally tubular metallic body. The tubular metallic body having a first portion, a second portion integral with the first portion having a smooth cylindrical outer surface adapted to be inserted into the conduit and a formed rounded rolled-over nose at its outer end, a longitudinally directed internal passage extending through the tubular body for receiving fluid flow, a first and second annular groove formed in the second portion axially spaced from each other, a first essentially constant diameter portion extending between the first annular groove and the second annular groove, and a second essentially constant diameter portion extending between the first annular groove and the first end portion.
