As the fitting nipple screws into the hose, the rubber is compressed and a bulge forms directly in front of the nipple. By compressing the bulge we prevent the nipple from cutting through the bulge and cutting a rubber flap from the hose inner tube. If the mandrel was the same diameter as the nipple then the bulge is fully compressed and the nipple cannot cut a flap.
