ABSTRACT:
The invention relates to an axially-swaged male end fitting assembly compatible with a standard 24.degree. cone flareless female fitting. The fitting may be fabricated from a sleeve and a tube that are axially swaged within a tool assembly. The sleeve includes a rounded shoulder, a partially conical nose, and a cylindrical inner surface. The inner surface includes a groove at the tip of the nose, and another groove positioned axially close enough to the shoulder to be radially deformed during axial swaging. The tool assembly includes a swaging tool, a female die and a ring die. The female die includes a tapered surface positioned and sized to preset the nose into the tube. The female die also has a surface confronting the sleeve shoulder, for controlling the amount of preset that occurs. The ring die includes a tapered surface positioned and sized to swage the shoulder into the tube. The ring die may be sized to be received around the female die after swaging, freeing the sleeve from contact with the ring die's swaging surfaces.
