3/16 in Brake Line Forming Tool Set – Single & Double Flare

Brake Line Forming Tool Set – 3/16 in Single & Double Flare

Get precise, professional-quality brake line flares without a hydraulic press or specialty shop. This manual brake tubing forming tool set handles both single and double-end flaring on 3/16 in tubing — covering the most common brake line sizes used in automotive repair and fabrication work. Made in Mainland China.

Key Features

• Single & Double Flare Capability: Swap between the included single and double forming heads to handle a wide range of brake line repair and replacement jobs with one compact kit.
• Detachable Leverage Handle: The removable grip lets you apply steady, controlled hand force during forming, and detaches easily so the tool can be repositioned in tight garage spaces.
• Alloy Steel Construction: The main body is built from industrial-grade, high-strength alloy steel with high-frequency quenching heat treatment and a rust-resistant finish — built to hold up through repeat repair sessions.
• Broad Tube Material Compatibility: Works with copper, aluminum, soft steel, and Kunifer (copper-nickel) brake tubing in the 3/16 in size. Not intended for hardened stainless or hardened steel tubing.
• Complete Kit with Carry Case: Comes with the forming tool body, detachable handle, positioning screw, single and double forming heads, die grease, and a molded storage case — everything stays organized for transport and repeat use.

Frequently Asked Questions

Q: What tubing size does this brake line forming tool set work with?

A: This tool is designed specifically for 3/16 in (approximately 4.75 mm) brake tubing — the most common size used in automotive brake line repair and replacement. It is compatible with copper, aluminum, soft steel, and Kunifer (copper-nickel) tubing in that size.

Q: What is the difference between single and double flaring, and does this kit do both?

A: A single flare creates one outward roll at the end of the tube, while a double flare folds the material back on itself for added strength and leak resistance — the preferred standard for most automotive brake lines. Yes, this kit includes both a single forming head and a double forming head so you can perform either type of flare.

Q: Is the handle permanently attached, and why is a detachable handle useful?

A: No — the leverage handle is detachable by design. This allows you to remove or reposition the handle when working in tight engine bays or cramped garage spaces, and then reattach it to apply the leverage needed for consistent, controlled tube forming.

Q: Can this tool be used on stainless steel brake tubing?

A: This tool is not intended for hardened stainless steel or hardened steel tubing. It is designed for use with softer brake tube materials: copper, aluminum, soft steel, and Kunifer (copper-nickel alloy) in the 3/16 in size.
