SEEKSELF Brake Line Flaring Tool Kit – 37° & 45° Single, Double & Bubble Flares, 4 Sizes (3/16–3/8")

SEEKSELF Professional Brake Line Flaring Tool Kit makes clean 37° and 45° single, double and bubble flares on steel and copper brake tubing for reliable, leak-free connections.

This comprehensive flaring set supplies everything needed to form precise flares on common automotive and plumbing tubing sizes: 3/16" (4.75mm), 1/4" (6.35mm), 5/16" (8mm) and 3/8" (9.5mm). Built from durable steel with split dies and a vise-mounted body, the kit is designed for bench use to deliver repeatable results when repairing or fabricating brake lines, fuel lines or hydraulic tubing. A molded plastic case keeps components organized for shop or mobile use.

How does the kit create different flare types?

The tool uses interchangeable turntables and split dies to shape tubing ends into 37° or 45° single flares, 45° double flares, and bubble flares. Swap the 37° or 45° turntable and choose the matching split die for the tube diameter, then clamp the tube and actuate the press to form the flare.

• Includes both 37° and 45° turntables for SAE and metric fittings.
• Split dies in four sizes match 3/16", 1/4", 5/16" and 3/8" tubing.
• Long lever handle and screw press for controlled forming pressure.
• Bubble-flare capability for soft metals and specific hydraulic fittings.

What tubing materials and sizes are compatible?

This flaring kit is suitable for common brake and fuel tubing materials like steel, stainless steel and softer metals such as copper. It supports the four most-used outer diameters for light-vehicle brake and hydraulic systems, and it includes metric-friendly sizing for broader compatibility.

• Supported O.D.: 3/16" (4.75mm), 1/4" (6.35mm), 5/16" (8mm), 3/8" (9.5mm).
• Works on steel, stainless steel, and softer metals (e.g., copper).
• Not intended for on-vehicle clamping—mount to a bench vise before use.
• Split die limiting holes reduce slipping during forming for consistent results.

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

Clamp the tool body securely in a reliable bench vise before beginning; do not use the tool while it is mounted to a vehicle. Fit the correct split die and turntable, center the tubing, and tighten the screw press while wearing safety glasses and gloves to protect from metal chips.

• Firmly mount the flaring body to a vise; do not operate under a vehicle.
• Wear eye protection and gloves; keep bystanders clear of chips and debris.
• Use the die limiting hole and slow, controlled turns for even flares.
• Follow the included graphic instruction manual for step-by-step guidance.

What comes in the kit and how is it organized?

The set arrives with the flaring body, both 37° and 45° turntables, eight split dies covering the four sizes for each angle, a long handle for leverage, an instruction manual and a plastic carry case. Parts fit into molded slots so you can keep dies matched to each turntable and reduce setup time in the shop.

• Flaring tool body (vise-mounted) plus long lever handle.
• 37° and 45° turntables with four split dies each (8 dies total).
• Fits metric and SAE common brake line diameters for versatility.
• Durable plastic suitcase for transport and storage.

Who is this for: The SEEKSELF flaring kit suits DIY mechanics, professional technicians and hobby fabricators who need a bench-mounted solution for forming accurate brake, fuel or hydraulic tube flares. It’s aimed at users who value durable steel construction, interchangeable dies for multiple flare types, and a neatly organized kit for regular shop work or mobile servicing. If you require on-vehicle flaring or specialize in oversized tubing, consider a dedicated on-car flaring tool or larger-capacity equipment.
