Lisle Double Flaring Tool Kit for 3/16" & 1/4" Tubing - Low-Profile, Vise & Depth Stop

The Lisle 33260 Double Flaring Tool Kit is a compact, low-profile flaring set designed to form reliable single and double flares on 3/16" (4.75mm) and 1/4" brake and fuel tubing in confined spaces.

When working on automotive brake, fuel or hydraulic lines, having a flaring tool that fits into tight areas makes repair and fabrication faster and cleaner. The Lisle 33260 kit combines a low-profile yoke and a secure vise assembly so you can center tubing without marring the surface, and a depth stop to control tubing protrusion for consistent flare formation. Note that this model is intended for soft metal tubing and is not compatible with stainless steel.

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

The slim yoke and compact clamp geometry let you position the tool where bulkier kits won't fit, reducing disassembly time and improving access to lines routed near components. You can form accurate flares without needing to remove nearby brackets or hoses.

• Low-profile yoke fits between tight mounting points.
• Short clearance height enables use near manifolds and frames.
• Reduces need to unbolt adjacent components for access.

Can this kit make both single and double flares, and how precise are they?

The Lisle 33260 can create both single and double flares on 3/16" and 1/4" tubing with controlled depth via an integrated stop. The vise assembly centers tubing and grips it without leaving marks, so each flare stays concentric and consistent for reliable fitting and sealing.

• Works with 3/16" (4.75mm) and 1/4" tubing sizes.
• Depth stop ensures the correct tubing length for repeatable flares.
• Vise holds tubing centered and prevents surface marring.

What are the material and compatibility limits I should know about?

This tool is built for soft metal tubing commonly used in automotive brake and fuel lines; it is not rated for stainless tubing. Using it on hardened or stainless materials can damage the dies and produce poor flares, so choose tubing type accordingly.

• Designed for mild steel, copper, and similar soft tubing materials.
• Not suitable for stainless steel tubing — avoid use on hardened metals.
• Ideal for maintenance, repair, and small-scale fabrication tasks.

How do I set up and use the depth stop and vise for best results?

Clamp the tubing in the vise assembly so the tube ends align with the depth stop, then tighten until it is centered and snug without over-compression. Use the proper adapter for single or double flares and operate the yoke evenly to form a clean lip; check the flare visually and re-seat if necessary.

• Seat tubing against the depth stop before tightening the vise.
• Select the correct cone/adaptor for single or double flares.
• Apply even pressure during forming to avoid uneven flares.

Who is this for? The Lisle 33260 is aimed at DIY mechanics, professional technicians, and hobbyists who need a compact, dependable flaring tool for routine brake, fuel or hydraulic line service where space is limited. If you work on older vehicles, custom brake lines, or tight engine compartments and use soft tubing, this kit offers the control and portability to produce repeatable single or double flares. If you frequently work with stainless or hardened tubing, choose a tool rated for those materials instead.
