Built from heat-treated steel with rotating die heads for both 37° and 45° flares, the tool clamps in a vise and converts standard tubing into correctly profiled fittings used in many automotive and hydraulic systems. The set includes split dies for common diameters, a lever handle, reaming\/reamer cones, and a molded carrying case so you can store and transport the kit safely.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tool make different types of flares (single, double, bubble)?\u003c\/h3\u003e\n\u003cp\u003eThe DPTOOL kit uses a rotating die head and a sequence of reaming cones to form each flare type. You change positions on the die head and use the numbered cones OP.0, OP.1 and OP.2 in the prescribed order to produce single, double or bubble flares reliably.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle flare: set die head to OP.0 then OP.2, press with reamer as instructed.\u003c\/li\u003e\n  \u003cli\u003eBubble flare: use OP.0 then OP.1 to form the rounded bubble profile.\u003c\/li\u003e\n  \u003cli\u003eDouble flare: follow OP.0 → OP.1 → OP.2 sequence for a folded double lip.\u003c\/li\u003e\n  \u003cli\u003eUse a vise-mounted base for consistent alignment and repeatability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat tube sizes and materials will this flaring tool work with?\u003c\/h3\u003e\n\u003cp\u003eThis kit covers the most common automotive tubing diameters and handles a range of materials.
