Built from aluminum alloy for portability, it supports common inch-sized tube diameters and is intended for soft metals such as copper and aluminum. The tool is focused on single 45° flares only and is optimized for field service, repair, and light fabrication jobs in HVAC, refrigeration, and similar trades.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the eccentric cone improve flare quality?\u003c\/h3\u003e\n\u003cp\u003eThe eccentric-type cone rolls through the tube end as it forms the flare, producing a smooth metal flow and even flare walls across the full circumference. This rolling action reduces localized wear on the cone and minimizes thin spots on the flare, helping create reliable seating surfaces for fittings.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEccentrically mounted hardened-steel cone for rolling metal flow\u003c\/li\u003e\n  \u003cli\u003eUniform wall thickness reduces leak-prone thin areas\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for single 45° flares on soft tubing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat features make the tool fast and easy to use on job sites?\u003c\/h3\u003e\n\u003cp\u003eThe built-in limit piece lets you set a precise tube insertion depth so each flare starts at the same position without repeated measuring. A clutch in the rotating handle disengages automatically when the flare cycle finishes, preventing overworking the cone or tube and simplifying one-handed operation in tight spaces.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eLimit piece gives repeatable tube length control for consistent flares\u003c\/li\u003e\n  \u003cli\u003eRotating handle with clutch disconnects when complete to avoid overtightening\u003c\/li\u003e\n  \u003cli\u003eAluminum alloy frame keeps the tool under 1 kg for reduced fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich tube sizes and materials are compatible with this flaring tool?\u003c\/h3\u003e\n\u003cp\u003eThis Bonvoisin tool supports common inch-size outer diameters used in HVAC and refrigeration: 1\/4\", 5\/16\", 3\/8\", 1\/2\", 5\/8\", and 3\/4\".
