Titan 3/16-Inch Double Flaring Tool Kit 51535 — Compact On-Vehicle Design, Removable Handle

Titan 51535 is a compact, vehicle-ready 3/16-inch double flaring tool kit that forms reliable inverted 45° SAE double flares for most automotive brake lines.

Whether you're rebuilding brake lines or fixing a leak, the Titan 51535 double flaring tool gives you the hardware and instructions to create consistent, professional-grade inverted 45-degree flares on 3/16-inch steel and nickel-copper tubing. Designed to work in cramped under-car spaces, this kit lets you make repairs on the vehicle without removing long runs of tubing, saving time and minimizing disassembly.

How does this tool create a proper double flare for brake lines?

The tool uses a two-step forming process: first the tube edge is folded (pre-flare) and then the cone-forming die compresses that fold into an inverted 45° SAE double flare. Included punch and die lubrication help the metal flow cleanly for a tight, leak-resistant seat.

• Creates inverted 45° SAE double flares for 3/16-inch tubing.
• Double-ended OP1/OP2 punch enables correct pre-flare sizing.
• Grand 66A die lubricant reduces scoring and eases forming.
• Detailed instructions guide each step for consistent results.

Can I use the Titan 51535 without removing the brake line from the vehicle?

Yes — the compact build is specifically intended for on-vehicle repairs in tight spaces beneath cars and trucks. The removable handle and low-profile clamp let you position and operate the tool where full removal would be difficult.

• Compact body fits between chassis and suspension components.
• Removable handle allows bench-vise or confined-space use.
• Positioning bolt helps secure the tool to the tubing while flaring.

What parts are included and how do they help the process?

The kit contains the flaring yoke with removable handle, a positioning bolt, a double-ended OP1/OP2 punch for accurate pre-flare shaping, and a container of Grand 66A die lubricant to protect tube surfaces during forming. Each component is selected to produce repeatable flares for 3/16-inch brake lines.

• 3/16-inch double flaring tool with removable handle — main clamping and forming assembly.
• Positioning bolt — secures tubing alignment for straight flares.
• Double-ended OP1/OP2 punch — sizes and pre-forms the tube correctly.
• Grand 66A lubricant — prevents galling and ensures smooth metal flow.

Is the Titan 51535 suitable for all brake-line materials and vehicles?

The tool is designed for 3/16-inch steel and nickel-copper tubing commonly used on passenger cars and trucks. It is not recommended for stainless steel tubing; stainless requires specialized tooling and techniques to avoid cracking or improper flares.

• Best for standard 3/16-inch steel and nickel-copper brake lines.
• Not recommended for stainless steel tubing.
• Works with most cars and light trucks that use 3/16-inch brake lines.

Who is this for: The Titan 51535 kit is aimed at automotive DIYers, independent mechanics, and fleet technicians who need a reliable, portable flaring solution for on-vehicle brake-line repair. If you work on passenger cars or light trucks with 3/16-inch brake tubing and want a durable, easy-to-learn tool that reduces disassembly, this kit delivers the parts and instructions to get the job done.
