Flare Nut Wrenches

Flare nut wrenches are basic tools used in the automotive field, plumbing, and various repairs. They are visually similar to their box-end counterparts, yet with two substantial differences. First, the “box” is open, as a small part of the end section is missing so that the wrench can go over a tube or line to grip the nut. Second, the end section is especially thick, compared to common box-end or open-end wrenches, to increase the contact area between the tool and nut.

The thick jaws ensure that brass and copper nuts, typically used in plumbing, won't get damaged when engaged by the wrench. Also, these products are indispensable when it comes to working on cars; for example, they are a must to loosen or tighten brake lines nuts, sensor nuts, or fuel hose nuts. Typically, these tools have six- or twelve-point ends; some models feature openable ends to even improve fitting.
