Ratcheting Flex Head Flare Nut Wrench Set 5-Piece SAE

GEARWRENCH 89100: five double-end flare nut wrenches, covering 1/4 x 5/16, 3/8 x 7/16, 1/2 x 9/16, 5/8 x 11/16 and 3/4 x 7/8 in. Each head ratchets and each head flexes, so you can set the wrench on a cooler line fitting buried behind a crossmember, angle the handle to whatever clearance you have, and keep working the nut without lifting the wrench off between swings.

That matters on the fittings a socket cannot reach. A flare nut socket needs the line to feed straight through it and needs room behind the nut for the ratchet. On a transmission cooler line that turns hard at the case, or a brake line running tight along the frame rail, there is no such room. A ratcheting flex head wrench works in the few degrees of arc you actually have.

The heads are six-point and hex-shaped, which spreads the load across the flats of a soft line nut instead of pinching two corners. Alloy steel, polished chrome, hang-hole ends. GEARWRENCH backs these with their standard limited lifetime warranty. Five wrenches, ten sizes, one roll.
