ZUXUSE Brake Line Flaring Tool Kit — 3/16" & 1/4" Double Flaring, Carbon-Steel Handheld

The ZUXUSE Brake Line Flaring Tool Kit is a compact, carbon-steel set that creates reliable 45° SAE double flares, single flares and bubble flares for 3/16" and 1/4" tubing used in brake and hydraulic lines.

This handheld kit is built to make brake-line and hydraulic-tube repairs faster and more precise. Designed for copper, aluminum and nickel-copper tubing, the set includes detachable handles, double-ended punches, alignment bolts, lubricant and a hex wrench so you can flare lines on the vehicle or at a workbench. The durable forged carbon-steel construction and positive locking clamp help hold tubes steady to produce clean, leak-resistant flares.

How does the ZUXUSE kit create different flare types?

The tool uses interchangeable punches and a multi-position yoke to form 45° double flares, single flares and bubble flares without damaging tubing. The kit’s OP1 double-ended punches and accurately machined clamp ensure the tubing aligns properly with the die, while the lubricant lowers friction for smoother forming.

• Creates 45° SAE double flares ideal for brake fittings
• Single and bubble flares available by changing punch orientation
• Two double-ended OP1 punches cover both flare styles
• Lubricant included to reduce chipping and improve finish

What tube sizes and materials can I use with this flaring tool?

This kit is optimized for 3/16" (4.8 mm) and 1/4" (6.35 mm) tubes commonly found in brake and hydraulic systems. It performs well with softer metals—copper, aluminum and nickel-copper—where the tool can form clean, consistent flares. Avoid stainless steel tubing because its hardness exceeds the tool’s designed capacity and risks damage.

• Compatible sizes: 3/16" and 1/4" tubing
• Suitable materials: copper, aluminum, nickel-copper
• Not recommended for stainless steel tubing
• Particularly good for standard automotive brake/hydraulic lines

Can I use this kit in tight spaces or on-vehicle?

The compact, handheld clamp and detachable handles let you work in cramped areas, under vehicles, or wherever the line sits without removing long tube runs. If you prefer bench work, the tool disassembles so you can mount the clamp in a vise for steadier leverage and repeatable results.

• Handheld design for access under dash or vehicle
• Detachable handles allow bench-vise mounting
• Positive tube lock prevents slippage during forming
• Saves time by avoiding full tube removal for flaring

What’s included and how does build quality affect performance?

The 7-piece set supplies what you need to flare and maintain brake lines: the dual flaring clamp with removable handles, two double-ended OP1 punches, two alignment bolts, a small bottle of mold lubricant, and a hex wrench. Forged carbon-steel components resist wear and keep alignment tight, which helps produce consistent flares and extends tool life.

• 7-piece kit: clamp, 2 punches, 2 bolts, lubricant, hex wrench
• Forged carbon steel for durability and alignment stability
• Included lubricant prevents scoring and improves finish
• Hex wrench and bolts simplify punch swapping and setup

Who is this for? The ZUXUSE Brake Line Flaring Tool Kit suits DIY mechanics, professional technicians, and hobbyists who service brake and hydraulic lines using copper, aluminum or nickel-copper tubing. It’s especially useful if you need a portable, reliable flaring solution for on-vehicle repairs or a compact bench tool for occasional shop tasks. Avoid this kit if you routinely flare stainless steel tubing or require large industrial sizes beyond 1/4".
