Lisle 33260 Flaring Tool - Compact Brake Line Flaring Tool

In this review the Lisle 33260 flaring tool is evaluated for DIY mechanics and professional technicians who need reliable single and double flares on small brake and fuel lines. The bottom line: it creates consistent, clean flares on 3/16' and 1/4' tubing and its low profile design makes it useful where space is limited. Our review finds it particularly strong for complete line replacement jobs where durability and flare quality matter more than a large, heavy bench tool.

Key Features

• Dual flare capability: Creates single or double flares on 3/16' (4.75 mm) and 1/4' tubing so it covers the common sizes used on many brake and fuel systems.
• Low profile design: The compact head allows tubing to be flared in tight spaces where bulkier tools cannot reach.
• Secure vise assembly: The vise holds tubing centered and firmly without marring, producing a concentric flare every time.
• Depth stop: Built-in depth stop ensures proper tubing length in the clamp for repeatable flares and reduces setup errors.
• Compact build quality: Customers note the tool is solidly constructed and small enough to maneuver in cramped engine bays.

Who It's For

This tool is aimed at home mechanics, restoration enthusiasts, and professional technicians who work on brake or fuel lines made from copper, nickel, or similar small-diameter tubing and who need reliable single or double flares. Its compact footprint is a real advantage for working on vehicles with limited access or on assemblies mounted close to bodywork.

It is less suited for shops that routinely flare larger-diameter tubing beyond 1/4' or for users who prefer a heavy bench-mounted flaring station; in those cases a larger tool designed for heavier-duty or larger tubing would be a better choice.

Pros & Cons

Pros

• Produces consistent double inverted flares suitable for brake line replacement and repair.
• Low profile and compact size lets users work in tight spaces where other tools cannot fit.
• Vise assembly centers tubing without marring, improving final fit and sealing.
• Depth stop helps achieve repeatable tubing length and reduces setup time.

Cons

• Limited to 3/16' and 1/4' tubing sizes, so not appropriate for larger lines.
• The compact design is excellent for access but may feel less substantial than larger bench tools for high-volume shop work.
