Using patented technology, SMC and AGS offer the unique design of the WTF (Won't Trash Flarenuts) 4-in-1 ratcheting flare nut wrench which allows one tool to work on all the four most popular sizes of flarenuts (3/8” and 7/16”, 10mm and 11mm). To operate, the tool opens, goes over the brake-line, grips on all six faces of the flarenut, and ratchets until the nut is finger loose and can then be simply removed.
