This is a revolution in brazing technology, delivering precision and consistency in creating fittings perfect for brazed joints. Using compressed air and an adjustable depth stop, it quickly modifies fittings up to a 1/8th inch thick, providing a seamless transition from a solder joint fitting to a brazed-joint fitting in seconds.  For fittings over 4-inch, you will need the Heavy duty Brazing Dimpler™ tool since larger fittings are thicker and additional force is needed to dimple thicker fittings.
