SKU: LTCF-SAE

The 4LifetimeLines Crowfoot Flare Nut Wrench Set is a 6-piece set of 3/8" drive crowfoot flare nut wrenches on a storage rail, in SAE (3/8"–3/4") or metric (10–17mm) sizes. A crowfoot is an open-ended wrench head with no handle: it mounts on a 3/8" ratchet, extension or torque wrench to reach flare nuts behind lines, brackets and firewalls.

What's in the box

6 crowfoot flare nut wrenches in the size set you choose
3/8" storage rail

How to use it with a torque wrench

Mount the crowfoot at 90° to the torque wrench handle. The effective length doesn't change, so the torque reading stays accurate. 4LifetimeLines says the flare nut profile grips five flats instead of two, which helps protect soft brass and rusted fittings from rounding.

Questions

SAE or metric? Match the set to your flare nuts: the SAE set covers 3/8"–3/4" and the metric set covers 10–17mm.

Can you use a crowfoot wrench with a torque wrench? Yes. Set the crowfoot 90° to the handle so the effective length, and your reading, stays accurate.

Crowfoot or line wrench? A line wrench for hand work and breaking fittings loose; a crowfoot when you need ratchet access or a torque wrench on the nut.
