Abstract
A forming die system and method is used in end forming a pipe or tube for connecting the pipe or tube with a fitting without a sleeve therebetween. The forming die system includes engageable outer dies that together define a bore having a longitudinal axis, die forming surfaces formed on each outer die, grip dies supported in each of the outer dies and configured to hold the pipe or tube, a biasing member that is engageable between a corresponding one of the outer dies and a corresponding one of the grip dies, and a forming pin that is configured to roll around the longitudinal axis in a circular motion at a predetermined angle relative to the longitudinal axis.
