The 7 Best Flare Nut Wrench Sets

Updated September 08, 2019 by Rafael Perez

This wiki has been updated 15 times since it was first published in August of 2019. Flare nut wrenches are specifically designed to tighten hex-style fasteners that are typically attached to fluid or gas lines. They have thick walls and extend around the nut more than standard wrenches, which helps prevent the rounding that can occur because of the soft metals used on plumbing nuts. Our selections considered affordability, durability, and the quality of the materials used. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki.

Editor's Notes

September 04, 2019:

As soon as you try to use a standard open-ended wrench on a flare nut, you know that you need to buy a set of flare nut wrenches. The soft metals that these fasteners are made out of are especially prone to rounding and you need the extra corners to prevent it.

We included both full sized wrench sets like the SK Superkrome 373 and crow's-foot versions like the Neiko 03323A because they are both necessary depending on the circumstances. The SKs are very nicely made and will last a lifetime. The Craftsman 44096 are a great option for those that want a dependable tool but do not want to spend the extra money for the premium quality.

Working on hydraulic systems can be dangerous and should only be done by trained technicians to avoid personal injury and damage to equipment.
