Titan 1/4-Inch Double Flaring Tool 51515 — Compact 1/4" double-flare kit with removable handle

Titan 51515 is a compact 1/4-inch double flaring tool that produces precise inverted 45° SAE double flares for automotive brake and fuel lines.

Made to work in tight under-car spaces and built for durability, the Titan 51515 kit gives DIY mechanics and professional technicians the ability to form standard 1/4" double flares without removing tubing from the vehicle. The set is made in Taiwan and includes the flare body, a removable handle, positioning bolt, double-ended punch, and die lubricant so you can create repeatable flares on steel and nickel-copper tubing.

How does the Titan 51515 create a reliable double flare?

The tool uses a two-step forming process to fold and compress the tube end into an inverted 45° SAE double flare. First the tube is flared outward and then the punch compresses the flare into a tight, uniform profile that fits conventional brake fittings.

• Produces inverted 45° SAE double flares for 1/4" tubing
• Double-ended OP1/OP2 punch lets you shape and size the flare accurately
• Die lubricant included for smoother forming and reduced tool wear
• Removable handle enables bench-vise or in-vehicle use

Can I use this tool while the line is still on the vehicle?

Yes—the Titan 51515 is designed with a compact body to fit in confined areas beneath a vehicle, allowing you to flare lines in place. This saves time by eliminating the need to remove long runs of tubing before repair.

• Low-profile clamp fits between chassis members and suspension components
• Positioning bolt secures tubing quickly for one-handed alignment
• Removable handle option keeps the tool compact for tight spaces

Which tubing types and applications are compatible with this flare kit?

The kit is optimized for 1/4" automotive tubing, including steel and nickel-copper alloy lines commonly used in brake and fuel systems. It creates the SAE inverted 45° double flare standard for most vehicle fittings.

• Intended for 1/4" steel and nickel-copper brake or fuel tubing
• Produces fittings compatible with standard automotive connectors
• Works on both in-vehicle and bench-mounted tubing positions

What comes in the box and how does each part help?

The Titan 51515 kit contains everything required to form consistent double flares: the main flaring body, a removable handle for versatility, a positioning bolt to hold the tube, a double-ended punch for accurate forming, and die lubricant to protect parts and improve flare quality.

• Main 1/4" double flaring tool with removable handle for space-limited jobs
• Positioning bolt for secure tube clamping and alignment
• Double-ended OP1/OP2 punch for the two-stage flaring process
• Container of die lubricant to reduce friction and extend tool life

Who is this for: The Titan 51515 1/4-Inch Double Flaring Tool is built for automotive technicians, home mechanics, and anyone who needs a dependable flare kit that fits under vehicles. If you repair brake or fuel lines and want a compact, repeatable solution to form SAE inverted 45° double flares without removing tubing runs, this kit provides the key components and portability to get the job done.
