Abstract
There is provided a process that includes providing an extruded fitting having a bore formed therein. The bore is machined from one or both sides of the extruded fitting to provide a ledge on one side for interacting with a corresponding fitting and a stop on the other. A pipe and braze sleeve are placed in combination into the bore and engage the stop. The pipe and bore include anti-rotation and location irregularities formed thereon to maintain a desired orientation of the parts. A mandrel is used to deform the pipe and sleeve to the shape of the bore. The parts are then brazed in a furnace.
