takes up almost no storage space
Especially after it's chucked in File 13 after you use a Professional Grade flaring tool!

BTW, the Mastercool will do single 45 degree,ISO Bubble flares, feul line push connect (Ford and GM), transmission push connect, and 37 degree, all with 1 tool. The Fed-Hil also does the same. That K-D only does 2 types of flares, 45 degree singe and 45 degree double. You have to buy another tool to Bubble flares and 37 degree, and I don't think they even make one to do push connects. From the standpoint of an auto service professional, flexability and repeatabilty are very imprtant, as well as speed and precision. Home use tools just don't give you that.
