The Milwaukee Tool Double End Flare Nut Wrench features two open-end jaw sizes — 19mm and 21mm — designed to grip fuel, brake, and hydraulic line fittings securely without rounding off the flare nuts. The slim profile allows access to tight spaces around tubing and line connections common in automotive and plumbing applications.
Built for professional tradespeople and serious DIYers, this wrench delivers reliable torque on flare fittings where a standard open-end wrench may slip, helping you work faster and more safely on fluid system repairs and installations.
