Double Flaring Tool (CP21110-316) is a compact, all-in-one flaring tool that makes precise 45° SAE double flares on 3\/16 in. tubing faster and with less setup than older flaring methods.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThis lightweight tool is built for mechanics, DIYers, and restoration enthusiasts who need reliable double flares on brake, fuel, and hydraulic lines made from non-stainless steel, nickel, or copper tubing. Designed to work on-vehicle in tight spaces or detached for use in a bench vise, it streamlines the flaring process so you spend less time preparing and more time finishing the job. The removable die and minimal extra-tool requirement keep the setup simple: just a 10 mm and a 17 mm wrench are needed.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tool speed up creating 45° SAE double flares?\u003c\/h3\u003e\n\n\u003cp\u003eThe CP21110-316 reduces steps compared with traditional multi-part flaring kits by combining clamping and forming actions in a single compact unit. Its efficient design minimizes repositioning and tool changes so each flare takes less time from start to finish.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated clamp and cone for faster cycle times\u003c\/li\u003e\n  \u003cli\u003ePre-aligned die minimizes re-adjustments\u003c\/li\u003e\n  \u003cli\u003eDetachable die lets you finish stubborn jobs in a bench vise\u003c\/li\u003e\n  \u003cli\u003eWorks directly on-vehicle to avoid tubing removal delays\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat tube materials and sizes is the tool compatible with?\u003c\/h3\u003e\n\n\u003cp\u003eThis model is engineered specifically for 3\/16 in. (approximately 4.75 mm) tubing and performs best with non-stainless steel, nickel, and copper lines commonly used in automotive brake and fuel systems. It is not intended for stainless steel tubing; using appropriate tubing types ensures clean, consistent double flares.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for 3\/16 in.
