Bonvoisin Flaring Tool Kit — 5‑in‑1 45° Single Flare Tool for 1/4"–3/4" Copper & Aluminum with Pipe Cutter and Deburrer

Bonvoisin Flaring Tool Kit is a lightweight 5-in-1 set that makes precise 45° single flares in 1/4”–3/4” copper and aluminum tubing, and includes a pipe cutter and deburring knife for ready-to-install HVAC connections.

This compact kit brings the main tools HVAC technicians, refrigeration installers, and DIYers need to shape and finish soft metal tubing. Built around an eccentric hardened-steel flaring cone and a clutch-equipped rotating handle, the set focuses on consistent single-flare profiles and user convenience. It covers six common tube diameters and packages clamp blocks, a cutter, and a deburring blade in a portable assembly that weighs under one kilogram.

How does the eccentric cone improve flare consistency?

The eccentrically mounted hardened-steel cone creates a controlled rolling action as it forms the flare, which helps metal flow evenly and reduces uneven walls or scoring. Because the cone is designed to move off-center as it expands the tube, it avoids the scraping typical of simple push-style cones.

• Hardened-steel cone for durability and even metal flow
• Rolling action reduces friction and wear on flare edges
• Produces uniform single 45° flare profiles for reliable seals
• Compatible with Φ6/9/10/12/16/19mm (1/4"–3/4") tubing

What features speed up repetitive flaring jobs?

Two built-in convenience features reduce rework and fatigue: a limit piece lets you preset insertion depth for identical flare lengths, and the rotating handle contains a clutch that disengages automatically when the flare is finished. Together they cut setup time and help maintain consistent results across multiple fittings.

• Limit piece for repeatable tube insertion and consistent flare length
• Rotating-handle clutch stops over-torquing and prevents damage
• Lightweight aluminum alloy gantry allows longer work sessions
• Portable kit consolidates tools for on-site use

Which pipe sizes and materials can I use with this kit?

The kit supports common soft-metal tubing used in HVAC and refrigeration: copper and aluminum tubes with outer diameters from 1/4" to 3/4" (6, 9, 10, 12, 16, 19 mm). Note that the tool performs single 45° flares only; it is not designed to produce double flares.

• Fits 1/4", 5/16", 3/8", 1/2", 5/8", 3/4" tubes
• Works with soft copper and aluminum tubing
• Generates single 45° flares suitable for HVAC connections
• Not suitable for forming double-flare fittings

What tools are included and how do they help finish the job?

This 5-in-1 kit supplies the essential items to cut, prepare, clamp, and flare tubing on site. Each component is chosen to streamline the workflow from measurement to final flare without needing separate purchases.

• Gantry (frame) to hold clamps and flaring cone securely
• Millimeter flaring clamp and inch flaring clamp for various markings
• Pipe cutter sized for soft metal tube diameters included
• Burr trimming knife to deburr and smooth tube ends after cutting

Who is this for: The Bonvoisin Flaring Tool Kit is made for HVAC installers, refrigeration technicians, and handy homeowners who work with copper or aluminum tubing and need a compact, repeatable solution for single 45° flares. It’s most useful on service calls and small installations where portability, consistent flare geometry, and quick setup are priorities. If your work requires double flares or heavier-duty industrial metal forming, consider a dedicated double-flare tool; for routine HVAC tube work and field repairs, this kit offers the core tools in a light, user-friendly package.
