Capri Tools 1/4 in. Double Flaring Tool — 1/4" SAE Tubing, Portable All-in-One Clamp for Brake & Fuel Lines

The Capri Tools 1/4 in. Double Flaring Tool produces consistent 45° SAE double flares quickly and reliably for 1/4" non-stainless steel, nickel, and copper tubing.

This compact, all-in-one flaring tool is engineered to cut the time it takes to form professional-grade double flares while staying portable enough to use on-vehicle or off-vehicle in tight spaces. The removable die and simple operation mean fewer trips to the bench and less fiddling with adapters — the only additional tools required are a 10 mm and a 17 mm wrench. Built for technicians and DIYers who need accurate brake-line and fuel-line connections, it balances speed, repeatability, and convenience.

How does this tool make double flares faster than older models?

The Capri Tools design streamlines the flaring sequence and reduces repositioning, cutting the work time roughly in half compared to previous-generation tools. Precision-machined components align the tube and flaring cone so each flare seats uniformly without extra adjustments.

• Integrated clamp and cone reduce setup steps.
• Detachable die allows quicker preparation at a bench or on a vehicle.
• Fewer tool changes: only a 10 mm and 17 mm wrench needed.

Which tubing types and sizes will this flaring tool handle?

This model is specified for 1/4" tubing and works reliably with non-stainless steel, nickel, and copper tubing commonly used for brake and fuel applications. It is not intended for stainless steel tubing, which requires specialized tooling and higher forming forces.

• Accepts 1/4" (6.35 mm) SAE tubing sizes.
• Compatible with copper, nickel, and standard automotive soft steels.
• Not recommended for stainless steel lines.

Can I use this tool on a vehicle or only at a workbench?

The compact footprint and portable build let you form double flares both on the vehicle and off the vehicle in confined spaces. When extra leverage or clamping strength is required, remove the die and secure the tube in a bench vise for maximum grip and control.

• Small body fits into tight engine bays and undercarriage areas.
• Detachable die for bench-vise operation when needed.
• Lightweight construction for easy transport between job sites.

What accessories or additional tools do I need to start flaring?

The Capri Tools unit is essentially all-in-one: you only need a 10 mm and a 17 mm wrench to assemble and operate it. Standard tubing preparation tools (tube cutter, deburring tool) are recommended for best results but are not included.

• Required: 10 mm and 17 mm wrenches for setup and tightening.
• Recommended: tubing cutter and deburring tool for clean edges.
• Optional: bench vise for heavy-duty clamping when using the detached die.

Who this tool is for: The Capri Tools 1/4 in. Double Flaring Tool is aimed at automotive technicians, restoration enthusiasts, and home mechanics who need dependable 45° SAE double flares for brake, fuel, and other low-pressure lines. If you value speed, portability, and repeatable results on soft tubing materials — and prefer a simple setup that works in tight spaces — this tool fits that workflow. Avoid it only if you routinely flare stainless steel tubing or require fittings outside the 1/4" SAE size range.
