Standard ring spanners cannot be used on tube fittings because the tube prevents them from dropping over the nut; an open-end spanner contacts only two faces and rounds flare nuts under load. The flare nut wrench solves both problems: it contacts five or six flats of the nut for maximum grip while allowing the tube to pass through the opening. AIMS Industrial supplies flare nut wrenches in metric and imperial for automotive, hydraulic, and pneumatic tube work.\u003c\/p\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eFlare nut wrenches are essential for working on:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrake line fittings:\u003c\/strong\u003e Metric brake line nuts (10mm across flats is the most common for 3\/16\" and 5\/16\" brake pipe) corrode and are easily rounded by open-end spanners.

Individual spanners in frequently used sizes — 10mm, 12mm, and 17mm are the most common in automotive work — are a useful complement to the set.

A well-forged, chrome vanadium flare nut wrench maintains its shape under the torque required to crack a corroded fitting; a poor-quality tool will splay open, rounding the fitting nut and making a difficult job worse.
