An exemplary device and method for roller swaging a tube and a fitting includes a controller configured to terminate swaging in response to receiving a signal generated by a torque sensor. The torque sensor is configured to generate the signal indicative of a torque rise associated with a flow of tube material consisting of flow in an axial direction through a front or a rear of the fitting.
