Abstract
An internal swage fitting for swaging a tube. The fitting includes a tube connection region with one or more radial grooves and an expansion cavity at the end adjacent to the end of the tube to be swaged. The expansion cavity accommodates flowing tube material during the swaging process with minimal axial pressure on the fitting. The expansion cavity also includes a stop wall to fix the location of the tube in the fitting. The expansion cavity enables swaging of tube materials of relatively high ductility without accounting for setback. It therefore eliminates the need for a collar to establish setback during swaging.
