GEAROLL Brake Line Flaring Tool Kit 3/16-1/4 Dual-Size, 45-degree Single & Double Flares, Carbon-Steel

The GEAROLL Brake Line Flaring Tool Kit is a complete dual-size kit that makes reliable 45° single, double and bubble flares on 3/16" and 1/4" copper, aluminum and nickel-copper brake and hydraulic tubing.

If you service vehicle brake or hydraulic lines, this kit combines a sturdy flaring bar, OP1 punches, a detachable handle and a tube cutter to give professional-style flares without needing a shop press. The kit’s carbon-steel construction and molded carrying case keep parts organized while the included mold lubricant, hex wrench and gloves simplify setup and protect fittings during use.

How accurate are the flares produced by this tool?

The GEAROLL kit is engineered to create consistent 45° SAE double flares, single flares and bubble flares suitable for most automotive brake and hydraulic fittings. The clamping bar prevents tube slip and the OP1 punches center the flare for repeatable alignment.

• Creates precise 45° double and single flares
• Works on 3/16" and 1/4" tube sizes used in most vehicles
• Clamping design maintains concentricity and prevents movement
• Includes lubricant to reduce burrs and distortion

What materials and tube sizes can I safely flare?

This flaring tool is optimized for softer tubing: copper, aluminum and nickel-copper alloys commonly found in brake and hydraulic circuits. It is not designed for stainless steel tubing, which requires harder tooling because of its greater strength.

• Compatible: copper, aluminum, nickel-copper tubing
• Tube sizes: 3/16" and 1/4" (SAE standard)
• Not recommended: stainless steel tube—too hard for these punches
• Suitable for automotive brake lines and general hydraulic maintenance

What comes in the kit and how does it make the job easier?

The kit bundles everything needed to cut, clamp and form flares into a single portable case, reducing trips to the bench. A detachable handle speeds turning, the tube cutter creates clean ends, and the blow-molded case stores small parts so you won’t lose punches or bolts on the job.

• Dual flaring tool bar for 3/16" and 1/4" tubes with detachable handle
• Two double-ended OP1 punches for forming flares cleanly
• Tube cutter, hex wrench, mold lubricant, positioning bolts and gloves
• Instruction booklet and blow-molded case for organized storage

How durable and serviceable is the tool?

Key components are made from high-strength carbon steel to resist wear from repeated flaring operations. With proper cleaning and the included lubricant, the punches and bar maintain tolerance longer and provide consistent joints for routine maintenance tasks.

• High-strength carbon-steel construction for longevity
• Replaceable OP1 punches reduce long-term maintenance costs
• Simple hardware (positioning bolts and hex wrench) for quick adjustments
• Blow-molded case protects tools in transport and storage

Who is this for? The GEAROLL Brake Line Flaring Tool Kit is aimed at DIY mechanics, independent auto technicians and fleet maintenance personnel who need a compact, dependable flare solution for on-vehicle repairs and hydraulic line work. It’s a practical choice when you want shop-quality 45° flares on common tubing sizes without heavy equipment, provided you’re working with non-stainless brake or hydraulic lines.
