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

The SEEKSELF Professional Brake Line Flaring Tool Kit produces precise 45° single, double and bubble flares for 3/16", 1/4", 5/16", 3/8" and 4.75mm metal tubing.

This bench-mounted kit gives mechanics and DIYers a compact, durable solution for forming brake and fuel line flares in stainless steel, steel and softer metals such as copper. The set includes a heavy-duty flaring tool body, four split die sizes, a long lever handle and a plastic carry case. Built for workshop use, it clamps in a vise (not for under-car mounting) and comes with a visual instruction sheet to guide first-time users.

How does this tool create different flare types?

The SEEKSELF flaring tool uses interchangeable split dies and a tapered ram to shape pipe ends into 45° single flares, backed double flares, or bubble-style flares. Swapping dies adjusts the tool to the tubing outer diameter, while the ram forms the metal to the chosen flare profile.

• Includes split dies for 3/16" (4.75mm), 1/4" (6.35mm), 5/16" (8mm), 3/8" (9.5mm).
• Tapered flaring cone produces consistent 45° angles for sealing fittings.
• Die limiting holes prevent slippage during operation for repeatable results.

What materials and pipe sizes will it work with?

The kit is designed to handle stainless steel, ordinary steel and softer metals such as copper tubing commonly used in brake, fuel and hydraulic lines. It supports the most common workshop diameters listed on the dies for automotive and plumbing repairs.

• Compatible with 3/16", 1/4", 5/16", and 3/8" O.D. tubing (includes 4.75mm specification).
• Best for steel and copper; use appropriate force and lubrication for hardened stainless.
• Not intended for in-vehicle clamping — mount the tool securely in a bench vise.

How do I install and operate the flaring tool safely?

Secure the tool body in a reliable bench vise so it cannot move while you turn the handle. Wear eye protection and gloves, keep bystanders clear, and follow the included graphic manual for die selection and sequence to form single, double or bubble flares.

• Clamp the tool body into a vise; the kit is not for under-car use.
• Select the correct split die and insert tubing; tighten evenly before flaring.
• Turn the long lever handle left for easier, controlled force application.

What does the kit include and how is it packaged?

The SEEKSELF kit arrives organized in a protective plastic case with the main flaring body, four split dies, a long handle and a printed instruction sheet. The compact case keeps components secure and portable between job sites or garage storage.

• Flaring tool body (vise-mounted design) and long lever handle.
• Four split dies sized for 3/16", 1/4", 5/16" and 3/8" tubing.
• Instruction manual and sturdy plastic carrying case for transport and storage.
