Flare nut Wrenches

Flare nut wrenches, called line wrenches or crowfoot wrenches, are explicitly designed to work with flare nuts found on automotive brakes, fuel and hydraulic lines, and machinery hoses.

Flare nut wrenches have a distinct design, narrow profile, and rounded head that closely fits around flare nuts. Their round design provides better gripping power than regular wrenches to secure their hold without risk of slipperiness or rounding off of edges of flare nut edges, and often serve to provide sufficient torque in tight spaces where regular wrenches don’t fit as easily or are insufficiently capable.

Flare nut wrenches come in various sizes and are often made of high-grade materials like chrome-vanadium steel for increased durability and longevity. This tool is necessary for any mechanic or DIY enthusiast working on brake, fuel, or hydraulic systems.

There are various kinds of flare nut wrenches on the market, including:

  • Open-end flare nut wrench: This is the most widely-used form. Featuring an open end with a round profile designed to fit securely around any flare nut, an open-end flare nut wrench fits securely and snugly against its surface.
  • Box-end Flare Nut Wrench: This wrench features a closed-end design to give it greater grip on the nut, minimizing rounding-off of edges and less likely slipperiness than its open-ended counterparts.
  • Crowfoot Flare Nut Wrench: This wrench features a rounded head attached to a socket or extension and helps access flare nuts in hard-to-reach locations.
  • Ratcheting flare nut wrench: With this type of wrench equipped with a ratcheting mechanism, tightening or loosening the nut can be accomplished without needing to remove your wrench after each turn of the handle.
  • Flexible Flare Nut Wrench: This specialty wrench features an adjustable head that can be bent to reach flare nuts in tight or awkward spaces, such as brake lines, fuel lines, or hydraulic lines. It helps work efficiently when working on these systems.
