??Quality: The flare/swage will keep the coopers' malleability, which will ensure better couplings overall; the process also protects the tube from cracking. ??Material: Made of ball bearing steel, it is practical and durable. The flares will always have the same size and will fit perfectly; The swages present a perfect depth and a tight fitting, that will make the brazing easier, reducing the fatigue stress over the coupling area. ??Innovation: Revolutionizing system for molding tubes using heat by friction way more surface of contact between the flare and the Valve. ??Usage: Air conditioning installation, open copper tube, so that two copper tube mutual link.(To be installed on hand electric drill) ??Replace: You can use it to replace the old or brocken one. Package: Our package come with 6pcs copper pipe swaging tool drill bit.It is a good accessory to repair air condition
