Capri Tools 3/16 in. Double Flaring Tool - Fast, Compact Flare

In this review the Capri Tools 3/16 in. Double Flaring Tool is evaluated as a compact, no-frills solution for anyone who needs reliable 45-degree SAE double flares on 3/16 in. tubing. The bottom line: it is best for DIY mechanics and professional technicians who want a portable, all-in-one hand tool that cuts flaring time roughly in half compared with older designs. The tool's compact size and detachable die make it especially useful when working on brake lines on-vehicle or in tight spaces.

Key Features

• Fast operation: The design lets a user create 45-degree double flares in about half the time of older flaring tools, saving shop time.
• Compact portability: Its small footprint makes it easy to carry and use both off vehicle and on vehicle where space is tight.
• Material compatibility: Works flawlessly with 3/16 in. non-stainless steel, nickel, and copper tubing commonly found in brake systems.
• Detachable die: The removable die allows use in a bench vise for extra grip or for more controlled flaring work.
• All-in-one convenience: Everything needed is built into the tool so only a 10 mm and a 17 mm wrench are required to operate it.

Who It's For

The tool suits home mechanics, restoration hobbyists, and professional technicians who frequently work on vehicle brake lines or other 3/16 in. tubing and need a portable flaring solution. Its compact chassis and quick-action flaring make it ideal for jobs where access is limited or when carrying a minimal toolset is important.

Those who need flaring for tube sizes other than 3/16 in., or who prefer a powered flaring press for high-volume shop production, should look elsewhere; this tool is optimized for manual, precise work on 3/16 in. tubing.

Pros & Cons

Pros

• Produces consistent 45-degree SAE double flares for reliable brake-line connections.
• Compact design works well on-vehicle and in confined spaces where larger tools cannot reach.
• Detachable die lets you secure the tool in a bench vise for greater control when needed.
• Minimal additional tools required: only a 10 mm and a 17 mm wrench to operate.

Cons

• Some customers report occasional alignment issues, so careful setup is necessary to get perfect flares every time.
• Designed specifically for 3/16 in. tubing, so it is not a universal flaring tool for other tube sizes.
