SEEKSELF Brake Line Flaring Tool Kit – Vise-Mounted 45° Single/Double/Bubble Flares, 4 Die Sizes (3/16"–3/8")

SEEKSELF Professional Brake Line Flaring Tool Kit is a vise-mounted flaring set that forms 45° single, double and bubble flares on steel, stainless and soft metal tubing for automotive and plumbing work.

This compact kit brings workshop-grade flaring capability to home garages and professional bays. Built from hardened steel and supplied with four split die sizes, it accepts common brake and fuel line diameters: 3/16" (4.75mm), 1/4" (6.35mm), 5/16" (8mm) and 3/8" (9.5mm). The set is organized inside a durable plastic carry case and includes a long lever handle and simple paper instructions for quick setup.

How does the SEEKSELF kit create different flare types?

The tool body uses interchangeable split dies and a forming cone to produce 45° single flares, double flares and bubble (inverted) flares. Changing dies and adjusting the clamp depth determines the flare profile so fittings seal reliably when assembled.

• Four split die sizes match common tube O.D. for accurate centering
• Forming cone and yoke allow single, double and bubble flares
• Limiting holes on split dies prevent slipping during operation
• Long lever handle reduces torque needed to form hard metals

What materials and tube sizes will this tool work with?

The kit is intended for steel, stainless steel and softer metals such as copper. It handles standard brake and fuel line diameters used in most vehicles and many plumbing applications—verify tubing compatibility before flaring.

• Compatible O.D.s: 3/16" (4.75mm), 1/4" (6.35mm), 5/16" (8mm), 3/8" (9.5mm)
• Best for steel, stainless steel, and soft metals like copper
• Not suitable for pressurized operation on an installed vehicle—tool is vise-mounted
• Works for both automotive brake/fuel lines and small plumbing runs

How do I set up and use the flaring tool safely?

Clamp the tool base securely in a shop vise and choose the split die matching your tube diameter. Follow the included graphic instructions: cut square, deburr, seat tube in die, and form the flare with steady turns of the handle; always wear eye protection and gloves.

• Secure tool base in a reliable vise before use
• Use goggles and gloves; keep bystanders clear
• Turn the handle left for easier right-handed operation and controlled force
• Do not use the tool while under a vehicle or on pressurized lines

What comes in the package and how is the kit stored?

The set ships in a fitted plastic case to keep components organized and protected. All metal parts are housed for transport and the manual provides clear step-by-step graphics to get you flaring quickly.

• Vise-mounted brake line flaring tool body (steel construction)
• Four split dies for the four tube sizes listed above
• Long lever handle for reduced effort and improved torque control
• Paper graphic instruction manual and a compact plastic storage case

Who is this for: This SEEKSELF flaring kit is suited to DIY mechanics, restoration hobbyists, and professional technicians who need a compact, reliable way to form single, double and bubble flares on common brake and fuel tubing. It’s a practical choice for home garages and small shops that work on steel, stainless, or copper lines and want a portable, organized flaring solution without relying on expensive bench-only equipment.
