ATD Tools 5483 Master In-Line Flaring Tool Kit Unique design locks the adapters, cone and tube in a perfect line with less risk of breaking adapters The clamp and set screws put pressure directly over the tube reducing the chance of the tube slipping from the clamp; This increases the overall life of the clamp by not wearing down the teeth inside from repeated slipping The slender, low-profile design of this tool allows the user to make flares on the vehicle and in tight spaces Flares can be achieved along frame rails or areas in the engine compartment, saving the user time from having to remove components or complete lines to make repairs Set includes everything needed to do the following: 3/16", 1/4", 5/16 and 3/8" double and single flares; 4.75mm 6mm and 8mm double, bubble and single flares
