Review on DURATECH Flare Nut Wrench Set, SAE, 3-piece, 3/8'', 7/16'', 1/2'', 9/16'', 5/8'', 11/16'', High-Quality CR-V Steel, Organizer Pouch Included by Raj Mazzabufi

Needed a line wrench for doing brakes on a 2007 Mazda with 270,000 miles. Just by looking I knew a regular wrench would just round off the fittings on these OLD lines. Needed the 10mm so ordered this set. Sprayed the fittings with Kroil penetrant for 2 days while waiting for these to show up. The 10mm fit like a glove, I mean no wiggle room at all, which is what you want. This fitting didn't want to budge but the wrench did it's job with out even the slightest of deformation to the fitting. No rounding no nothing. Couldn't have loosened it with out these! So great when a regular wrench or vise grips won't do!
