Wostore Brake Line Flare Kit — SAE Double & ISO Bubble Flares, 7 Dies 3/16–5/8" with Cutter & Reamer

The Wostore Brake Line Flare Kit is a complete hand flaring set that makes single, SAE double and ISO bubble flares on soft metal tubing, plus includes a cutter, reamer and a durable carrying case.

Whether you're replacing brake lines, repairing fuel or transmission tubing, or making custom-length runs, this kit provides the dies and tools to cut, deburr and form professional flares on a range of tube sizes. Components are built for workshop use with a forged steel yoke, hardened flaring bar and a compact storage case so everything stays organized between jobs.

How do I make SAE double flares with this kit?

Creating an SAE double flare requires forming a single flare first, then folding it into a reinforced double flare. The Wostore kit supplies the correct size dies (3/16"–5/8") and a T-handle yoke to apply steady, even pressure for consistent results.

• Select the matching die for your tubing diameter and clamp the tube in the flaring bar.
• Use the cone to form the initial single flare, then re-seat and press to fold it into a double flare.
• Inspect the flare for concentricity and smooth edges; the kit's reamer helps finish the tube end first.

Can this kit handle ISO bubble (inverted) flares for metric fittings?

Yes — the flaring bar includes dies for ISO bubble (inverted) flares and metric sizes (4.75mm, 6mm, 8mm, 10mm). The hardened dies and stout yoke create the dome-shaped bubble flare used on many European and Asian vehicles.

• Choose the matching metric die and ensure the tube sits flush in the flaring bar slot.
• Use steady, even turns on the flaring cone until the bubble shape forms without cracks.
• Ream and clean the tube end first to prevent leaks and ensure a uniform seal.

What tube sizes and accessories are included in the kit?

The Wostore kit covers the most common automotive tubing sizes from 3/16" up to 5/8" plus popular metric diameters. It also includes a compact tube cutter and a pipe reamer so you can cut, deburr and flare without extra tools.

• Dies for 3/16", 1/4", 5/16", 3/8", 7/16", 1/2", 5/8", and metric 4.75mm, 6mm, 8mm, 10mm.
• T-handle forged steel yoke with hardened flaring bar for durability and control.
• Tubing cutter (3–22mm / 1/8"–7/8") and pipe reamer to prepare tube ends cleanly.
• Protective molded case keeps dies, cutter and reamer organized and portable.

How does this kit fit into a DIY or professional workflow?

It streamlines brake-line and fluid-line work by consolidating cutting, deburring and flaring into one portable set. The construction is robust for repeated use, making it suitable for backyard mechanics as well as mobile technicians who need a reliable tool kit on-site.

• Eliminates the need to source pre-flared lines; make custom lengths and fittings on demand.
• Durable materials reduce deformation under pressure and extend service life.
• Compact case fits in a toolbox or service van for fast access during repairs.

Who is this for? The Wostore Brake Line Flare Kit is intended for automotive technicians, restoration hobbyists, and competent DIYers who work on brake, fuel, transmission or hydraulic tubing and need a versatile, all-in-one flaring solution. If you value clean cuts, reliable flares and portable storage so you can make custom lines without outsourcing, this kit provides the essential dies and accessories to get professional results at the bench or roadside.
