KS TOOLS 1/2 tuuman Crowfoot jarruputkiavain, 24mm (913.1304)

In a busy automotive workshop, a technician reaches for this crowfoot flare nut wrench to loosen a stubborn brake line fitting on a 24mm union nut. The 1/2" square drive snaps onto a ratchet or torque wrench, allowing access in the tight space behind the wheel arch where a standard flare nut wrench cannot fit. The open-ended jaw slides over the line, grips the hex flats, and breaks the fitting free without rounding it off.

Why choose it

This crowfoot wrench is forged from hardened and tempered chrome vanadium steel, giving it the strength to handle high torque without deforming. The matt chrome plating provides corrosion resistance and a secure grip, even with oily hands.

Compatible with any 1/2" ratchet, extension, or torque wrench, it integrates seamlessly into your existing tool set.

Ideal use cases

• Loosening and tightening brake line fittings on cars and trucks
• Working on fuel lines, hydraulic lines, and power steering connections
• Torquing pipe unions in industrial machinery and agricultural equipment
• Accessing nuts in tight spaces where a standard wrench won't fit

Good to know

The crowfoot flare nut wrench is a specialty tool that combines the accessibility of a crowfoot with the grip of a flare nut wrench. The 24mm opening is sized for common metric fittings, and the 1/2" drive is standard for professional use. Always ensure the wrench is fully seated on the fitting before applying force to prevent slipping. This tool is sold individually and is not part of a set.
