Features:1. Quality: the flare or swage will keep the coopers' malleability, which will ensure better couplings overall, the process also protects the tube from cracking.2. 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.3. Innovation: revolutionizing system for molding tubes using heat by friction way more surface of contact between the flare and the valve.4. Usage: air conditioning installation, open copper tube, so that two copper tube mutual link. (To be installed on hand electric drill)5. Replace: you can use it to replace the old or brocken one. Our package come with 6pcs copper pipe swaging tool drill bit. It is a good accessory to repair air condition.
