Dual Head Flaring Tool creates ISO\/DIN bubble flares and 45° SAE double flares quickly on 4.75 mm (3\/16\") tubing.\u003c\/strong\u003e\n\n\u003cp\u003eThis compact, portable flaring tool combines two flare styles in a single unit so you can form reliable brake-line flares and fuel-line connections without swapping tools. Designed for 3\/16 in. (4.75 mm) non-stainless steel, nickel, and copper tubing, the tool’s single die produces ISO\/DIN bubble flares, SAE double flares, and SAE bubble flares. A removable die allows bench-vise use, while the low-profile body fits tight engine- bay locations for on-vehicle work.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tool save time compared with older flaring tools?\u003c\/h3\u003e\n\u003cp\u003eBy integrating both an ISO\/DIN bubble-flare head and a 45° SAE double-flare head into one device, you avoid changing attachments or carrying multiple tools. Its efficient clamp and mandrel action shortens setup and flare cycles.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-head design reduces tool swaps.\u003c\/li\u003e\n  \u003cli\u003eSingle die handles three flare types.\u003c\/li\u003e\n  \u003cli\u003eFast clamping action speeds each operation.\u003c\/li\u003e\n  \u003cli\u003eCompact body cuts setup time in tight spaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich tubing types and sizes are compatible with this tool?\u003c\/h3\u003e\n\u003cp\u003eThe tool is engineered specifically for 3\/16 in. (4.75 mm) tubing and works reliably with common soft metals used on brake and fuel systems. It is not intended for hardened stainless tubing without prior material-specific verification.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 3\/16 in.

What additional tools are required?\u003c\/h3\u003e\n\u003cp\u003eYes — the tool’s compact profile lets you form flares while the tubing remains installed, and the die detaches so you can secure it in a bench vise for greater leverage or precision. You only need two common wrenches to operate it.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompact form fits engine compartments and tight panels.\u003c\/li\u003e\n  \u003cli\u003eDetachable die enables bench-vise mounting for stability.\u003c\/li\u003e\n  \u003cli\u003eOnly a 10 mm and a 17 mm wrench are required for setup and operation.\u003c\/li\u003e\n  \u003cli\u003eLightweight and portable for field or garage use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat kind of flares does the single die create and why does that matter?\u003c\/h3\u003e\n\u003cp\u003eThe included die is versatile: it forms ISO\/DIN bubble flares commonly used in metric fittings and 45° SAE double flares often required in domestic brake systems. That versatility helps technicians adapt to different standards without extra dies.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eProduces ISO\/DIN bubble flares for metric connections.\u003c\/li\u003e\n  \u003cli\u003eForms 45° SAE double flares for traditional brake fittings.\u003c\/li\u003e\n  \u003cli\u003eAlso capable of SAE bubble flare where needed.\u003c\/li\u003e\n  \u003cli\u003eOne die reduces parts and simplifies inventory.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? Mechanics, automotive technicians, bicycle or small-engine repair professionals, and DIYers who work with 3\/16 in. metal tubing will benefit from this tool. It’s best suited for anyone who needs reliable bubble and double flares in confined locations or wants a single, portable flaring solution that handles common brake and fuel-line metals. Avoid use on unfamiliar hardened stainless tubing without confirmation of material compatibility.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What size tubing does this Capri Tools flaring tool fit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It is made for 3\/16 in.
