Whether it’s for a holiday or birthday, this Tools Under 30 Dollars Gift Guide Series shows you important, yet somewhat uncommon, tools that any gearhead would want.

Today, let’s talk about Flare Nut Wrenches.

***

You can find flare nut fittings on brake lines, fuel lines, household plumbing, and plenty of other places. And while you may be tempted to just grab the fittings with a regular wrench, don’t—unless you like rounded nuts.

As opposed to an ordinary wrench made from case-hardened steel, a flare nut wrench is typically made from a softer material to prevent you from damaging the nut. For a better grip, the flare wrench head wraps further around the nut than a traditional wrench too.

Many people, author included, have occasionally lucked out using regular wrenches on flare nuts. But try that on an old, corroded fitting and you’ve punched a one-way ticket to Roundsville (with stops at New Linesburg and Ruined Weekendia).

That’s why these wrenches are must-haves for anyone who works around any sort of plumbing. And these fittings come in a lot of different sizes, metric and standard, so it’s important to use the right one for the job.

A lot of folks don’t know about these tools, so they’re often a smart gift to give and receive. Better still, there’s a good chance you can find a set for under 30 bucks.
