Lisle Double Flaring Tool Kit for 3/16" & 1/4" Tubing — Low-Profile Clamp, Built-In Vise

Lisle 33260 is a compact double flaring tool kit that makes precise 3/16" and 1/4" double or single flares in soft tubing, designed for tight working spaces.

This low-profile flaring kit is built to form reliable single or double flares on 3/16" (4.75 mm) and 1/4" tubing used in brake, fuel, and hydraulic lines (excluding stainless tubing). Its slim clamp profile helps you work in cramped engine bays and under dash panels, while the integrated vise assembly centers and secures tubing without marring the surface. A depth-stop feature ensures consistent tubing length for repeatable, leak-resistant connections when used with compatible materials.

How does the Lisle 33260 handle tight spaces?

The tool’s low-profile clamp is specifically shaped to reach fittings and tubing runs in confined areas where bulkier flaring tools cannot fit. The compact head and short jaw spacing let you position the tool flush to the line and operate the flaring cone without excessive clearance.

• Low-profile clamp fits between engine components and behind panels.
• Short tool height allows use in shallow cavities.
• Ergonomic screw mechanism requires less swing space to actuate.

What kinds of flares and tubing sizes can I make with this kit?

The Lisle 33260 is designed to produce both double and single flares on two specific tubing sizes: 3/16" (4.75 mm) and 1/4". It gives a clean, uniform flare geometry appropriate for many automotive and light-equipment fluid lines when used on compatible soft metals such as copper, brass, or mild steel tubing (not stainless).

• Supported flare types: double flares and single flares.
• Compatible tube diameters: 3/16" (4.75 mm) and 1/4".
• Not recommended for stainless tubing or hard-drawn lines.

How does the tool protect tubing and ensure consistent length?

A built-in vise assembly holds tubing centered and grips without marring the surface, so fittings seat properly and threads remain intact. The depth-stop feature lets you preset the insertion length, which helps produce repeatable flares and reduces trimming or rework during installations.

• Vise jaws secure tubing while minimizing cosmetic damage.
• Centering action keeps the flare aligned with the tube axis.
• Depth stop guarantees consistent exposed tube length for repeat operations.

Which applications and materials should I avoid with this flaring tool?

While the Lisle 33260 covers the most common small-diameter tubing needs in automotive and light-industrial settings, it is not intended for stainless steel or very hard-drawn tubing. Using it on hardened materials can damage the tool and produce poor flares, so select compatible soft metals for best results.

• Avoid stainless steel and hardened automotive lines.
• Not suitable for tubing outside the 3/16" and 1/4" range.
• Use lubrication and correct seating to extend tool life and flare quality.

Who is this for: The Lisle 33260 double flaring tool kit is aimed at mechanics, plumbers of light fluid systems, home mechanics, and DIYers who need a compact, reliable flaring solution for brake, fuel, and hydraulic tubing in cramped work areas. Choose this kit if you often work with 3/16" or 1/4" soft tubing and require repeatable, centered flares without bulkier tooling — but opt for a specialized stainless flaring tool if you routinely handle hardened or stainless lines.
