Brake lines that fail inspection or weep fluid at the fitting need a   that seals the first time. This 30-piece hydraulic flaring tool kit makes 45-degree   on tubing from 3/16 to 1/2 inch. covering the common sizes found on cars. trucks. and light industrial equipment. The hydraulic press applies even pressure. so double   and ISO bubble   form cleanly on copper. steel. and nickel-copper alloy without cracking or splitting the tube wall.The set includes the hydraulic cylinder. a pump handle. dies and adapters for each tube size. plus a mini tube cutter and a deburring tool. Cut the line square. remove the burr. select the correct die. and pump the handle until the   is complete. The pressure relief valve prevents overloading. and the cylinder returns to the start position when released. All components store in a molded case that keeps the dies organized and the tools protected between jobs.This kit is designed for automotive brake and fuel line repair. transmission cooler lines. and air conditioning lines where a 45-degree double   is specified. Always double-check the   angle required by the vehicle manufacturer before starting. Keep the dies clean and lightly oiled to extend their life.
