Its eccentric hardened-steel cone creates a rolling metal flow for uniform flare walls while the built-in limit piece and clutch help control flare length and prevent overworking the fitting. The tool accepts common inch-size soft metal tubing and is optimized for portability and frequent field use.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the eccentric cone improve flare quality?\u003c\/h3\u003e\n\u003cp\u003eThe eccentrically mounted hardened steel cone produces a rolling action that pushes material outward evenly, yielding consistent wall thickness around the flare. This design reduces uneven stretching and wear compared with straight cones, especially on softer tubing like copper and aluminum. Expect more uniform single flares and fewer rejects when preparing connection ends.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHardened steel cone for durable forming\u003c\/li\u003e\n  \u003cli\u003eRolling action ensures even metal flow\u003c\/li\u003e\n  \u003cli\u003eProduces uniform 45° single flares across sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat do the clutch and limit piece do for speed and accuracy?\u003c\/h3\u003e\n\u003cp\u003eThe integrated clutch in the rotating handle disengages automatically once the flaring cycle is complete, which reduces the risk of over-torquing and makes repeated operations quicker. The limit piece sets the tube protrusion precisely so each flare starts at the same position without constant measurement. Together they speed up repetitive work and improve consistency in a production or service environment.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eClutch prevents over-rotation and handle strain\u003c\/li\u003e\n  \u003cli\u003eLimit piece sets consistent tube insertion depth\u003c\/li\u003e\n  \u003cli\u003eReduces rework and measurement guesswork\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich tube sizes and materials are compatible?\u003c\/h3\u003e\n\u003cp\u003eThis Bonvoisin flaring tool accepts inch-size soft metal tubing from 1\/4\" up to 3\/4\" outer diameter: 1\/4\", 5\/16\", 3\/8\", 1\/2\", 5\/8\", and 3\/4\". It is intended for single flares on copper and aluminum tubing typically found in HVAC, refrigeration, and related electrical systems.
