Titan 3/16-Inch Double Flaring Tool Kit — Compact SAE Brake Line Flare Tool for In-Vehicle Use

The Titan 51535 is a compact 3/16-inch double flaring tool kit designed to create reliable inverted 45° SAE double flares for automotive brake line repair, usable in tight spaces or mounted in a vise.

Designed for DIY mechanics and professional technicians, this portable flaring kit supplies the core components needed to form precise double flares on 3/16-inch steel and nickel-copper brake tubing. The tool’s compact body and removable handle let you work directly on the vehicle under cramped conditions or remove the handle for bench-vise operation. Included instructions and die lubricant help guide consistent results without sending fittings out for service.

How does this tool produce the correct SAE double flare?

The Titan 51535 uses a two-stage punching and spreading sequence that forms an inverted 45° double flare common in automotive brake systems. A matched punch and die geometry deliver consistent flare shape and wall compression to fit standard mating fittings.

• Includes a double-ended OP1/OP2 punch for forming the initial flare and rolling the lip.
• Tool body clamps tubing squarely to prevent misalignment during flaring.
• Comes with Grand 66A die lubricant to reduce friction and improve flare quality.

Can I use the Titan 51535 while the line is still on the vehicle?

Yes — the tool’s compact profile is engineered for in-vehicle use, letting you flare lines without removing long sections of tubing. The shorter jaw span and removable handle make it easier to position and operate in wheel wells and undercarriage spaces.

• Compact body fits into tight under-car spaces for on-vehicle repairs.
• Removable handle enables angled access or bench mounting in a vise.
• Positioning bolt secures the tubing so you can work with one hand free.

What tubing and fittings are compatible with this kit?

This kit is intended specifically for 3/16-inch SAE brake tubing, common on most cars and light trucks. It reliably forms inverted 45° double flares in steel and nickel-copper tubing; stainless steel is not recommended due to its greater springback and hardness.

• Designed for 3/16-inch brake tubing — fits standard automotive applications.
• Works best with steel and nickel-copper lines; avoid stainless tubing.
• Produces the SAE inverted 45° double flare used by most brake fittings.

What’s included and how does the kit help produce consistent results?

The kit supplies the essential parts and a lubricant to make repeatable flares without specialty extras. Clear instructions and the matched punch/die set reduce guesswork and help users achieve a proper seating surface for fittings.

• Kit contents: 3/16-inch double flaring tool with removable handle, positioning bolt, double-ended OP1/OP2 punch, and a container of Grand 66A die lubricant.
• Removable handle allows transition between on-vehicle use and bench-vise setup for stability.
• Lubricant minimizes galling and eases forming, improving flare finish.

Who is this for? The Titan 51535 is aimed at automotive hobbyists, mobile mechanics, and shop technicians who need a reliable, portable flaring tool for routine brake-line service. If you frequently repair or replace 3/16-inch brake tubing and want the option to flare lines in place or on a workbench, this kit offers the core capabilities to produce consistent inverted 45° double flares without specialized equipment.
