Lisle 33260 Flaring Tool — 3/16" & 1/4" Single/Double Flare, Low-Profile Head for Tight Spaces

The Lisle 33260 Flaring Tool makes accurate single or double flares on 3/16" (4.75mm) and 1/4" tubing while fitting into tight workspaces.

Compact and purpose-built, this flaring tool combines a low-profile head with a secure vise and depth stop to deliver repeatable flares for automotive and HVAC soft tubing. It’s engineered to center and hold standard tubing sizes without marring the surface, letting you form reliable seals where space is limited. Note: this model is not suitable for stainless tubing.

How does the low-profile design help in cramped engine bays?

The flattened head lets you position the tool where bulkier flaring tools won’t reach, so you can flare fittings behind manifolds, brackets, or near firewall openings. The compact shape reduces interference with surrounding components and improves visibility when aligning the tube.

• Slim head profile fits tight clearances.
• Accessible around obstructions and brackets.
• Improved sightline for precise tube placement.

Can I make both single and double flares with this tool?

Yes — the Lisle 33260 supports forming either single or double flares on the two specified tube diameters, letting you prepare lines for different fittings and repair standards. Switching between flare types is straightforward and designed for field or shop use.

• Produces single flares for flare-seat fittings.
• Forms double flares for stronger, vibration-resistant joints.
• Works on both 3/16" (4.75mm) and 1/4" tubing sizes.

What features improve accuracy and protect tubing?

The integrated vise assembly centers the tubing and locks it without causing surface damage, while an adjustable depth stop ensures you cut or bevel to the correct length before flaring. These elements reduce rework and help create uniform, leak-ready flares.

• Vise assembly clamps tubing squarely without marring.
• Depth stop sets consistent tube protrusion for repeatable flares.
• Durable construction for steady, reliable operation.

Are there any material or size limitations I should know about?

The tool is designed specifically for soft copper or soft aluminum tubing in 3/16" (4.75mm) and 1/4" diameters; it will not work on stainless tubing or sizes outside those ranges. Using incompatible materials can damage the tool and produce poor flare geometry.

• Compatible with 3/16" (4.75mm) tubing and 1/4" tubing only.
• Not rated for stainless tubing.
• Best used with softened/annealed tubing for clean flares.

Who is this for? Technicians, DIY mechanics, and HVAC or brake-line repairers who need a durable, space-conscious flaring solution will appreciate the Lisle 33260. It’s ideal for work in confined engine compartments, tight chassis locations, or any repair where a compact tool that still produces professional single or double flares is required. If you regularly flare 3/16" or 1/4" soft tubing and need consistent results without bulky tooling, this model is a practical choice.
