YIYITOOLS Brake Line Flaring Kit — 7‑Pc SAE 45° Single/Double/Bubble, Low‑Profile for 3/16" & 1/4" Tubing

The YIYITOOLS 7‑piece brake line flaring kit creates accurate 45° single, double and bubble flares for 3/16" and 1/4" SAE tubing, so you can repair brake and hydraulic lines with professional-fit results.

Whether you're restoring classic cars, maintaining a daily driver, or fabricating hydraulic lines, this compact flaring set provides the core tools to form clean, repeatable flares in copper, aluminum and nickel-copper tubing. Designed for workshop or roadside work, the kit focuses on repeatability and protection of the tube surface while offering the specific sizes most common to automotive brake systems.

How precise are the flares produced by this kit?

The kit is engineered to deliver consistent 45° single, double and bubble flares so fittings seat correctly and seal reliably. Its tooling and clamping geometry control tube alignment and flare angle to reduce leaks and rework.

• Produces 45° single, double and bubble flares for SAE applications.
• Tooling shaped to maintain concentricity and consistent flare thickness.
• Built-in depth stop sets exact tubing length for repeatable results.

What tubing sizes and materials will it work with?

This 7‑piece set is made for the most common brake line diameters: 3/16" and 1/4" SAE tubing. It performs well on softer metals typically used in vehicle brake and hydraulic lines, though it isn’t intended for stainless steel tubing.

• Compatible with 3/16" and 1/4" SAE brake/hydraulic tubing.
• Suitable for copper, aluminum and nickel‑copper alloys.
• Not recommended for stainless steel pipe or very hard alloys.

Can I use this kit in tight spaces or only on a bench vise?

The low‑profile clamp design lets you form flares under the vehicle or in cramped engine bays without removing long runs of tubing. If you prefer shop work, the kit can be mounted in a bench vise for more controlled, repeatable setups.

• Low profile body fits into restricted areas under cars.
• Clamp and vise assembly protect tubing from marring while holding it centered.
• Mountable on a bench vise for stable, off‑vehicle flaring.

What extras are included and what tools do I need?

The package contains all core flaring components so you can start working immediately; only two common wrenches are required to operate the set. That keeps the kit compact while still offering everything needed to form professional flares.

• Complete 7‑piece flaring set with dies and clamps.
• Includes a built‑in depth stop and protective vise assembly to prevent tube damage.
• Requires just a 10 mm and 17 mm wrench to operate—no extra specialized tools.

Who is this for? The YIYITOOLS 7‑Pc Brake Line Flaring Kit suits home mechanics, restoration hobbyists and small professional shops that work on vehicles or hydraulic systems using 3/16" and 1/4" SAE tubing. If you need reliable 45° single, double or bubble flares in copper, aluminum or nickel‑copper tubing and occasionally must work in confined spaces or on a bench, this compact, purpose-built kit covers the essentials without taking up bench real estate. It’s not meant for stainless steel pipe or industrial high‑hardness tubing.
