Wisscool Flaring Tool Kit 5-in-1 1/4–3/4 in (6–19 mm) Single 45° — Hardened Cone & Auto-Release Clutch

This compact 5-in-1 kit combines a hardened eccentric cone, easy clamp bars in both inch and metric sizes, and an auto-release clutch to deliver repeatable, leak-resistant flares. The set includes a built-in limit stop, a lightweight alloy gantry, a cutter and deburring tool, plus a carry case so technicians and DIYers can work cleanly on site without carrying extra parts.

How does the 45° eccentric flaring improve sealing compared to standard flares?

The eccentric cone design forces metal to flow uniformly around the tube end, producing a smoother, more concentric 45° seat that matches fittings better. That reduces the chance of gaps, cracks, or misalignment that can cause leaks under pressure.

• Hardened-steel eccentric cone for even metal displacement
• 45° single flare profile optimized for HVAC/R and common refrigerant fittings
• Reduces tube cracking and improves contact against flare fittings

What sizes and materials will this kit handle?

The kit includes both inch and metric clamp bars to cover the most common service sizes, so you can switch between dimension systems without extra adapters. It's rated for copper, aluminum, and mild steel tubing used in refrigeration and air-conditioning lines.

• Inch clamps: 1/4", 5/16", 3/8", 1/2", 5/8", 3/4" OD
• Metric clamps: 6, 9, 10, 12, 16, 19 mm OD
• Recommended for typical R134A and R410A flare connections

How does the auto-release clutch and limit stop save time and reduce errors?

The integrated limit stop sets the correct tube protrusion in seconds, eliminating guesswork and ensuring uniform flare length across multiple fittings. The auto-release clutch disengages when the flare finishes, preventing over-flaring and protecting the flare wall from deformation.

• Limit piece for consistent tube protrusion and less wasted tubing
• Clutch handle disengages automatically to stop over-tightening
• Reduces rework and protects the integrity of formed flares

What makes this kit portable and job-site friendly?

The main body is machined from a lightweight aluminum alloy to reduce fatigue during handheld use and to stand up to routine field wear. The organized kit includes clamps, cutter, deburrer, manual, and a compact carry box so components stay together between jobs.

• Alloy gantry weighs under 2.2 lb for easier handling
• Includes pipe cutter and deburring tool for finished tube ends
• Carry case keeps parts organized and ready for service calls

Who is this for: The Wisscool Flaring Tool Kit is aimed at HVAC and refrigeration technicians, contractors, and informed DIYers who need a compact, reliable flaring solution for 45° single flares across both inch and metric tubing. It suits anyone who wants faster setup, more consistent flare geometry, and fewer leaks on service or installation jobs without adding weight or bulky tools to their tool bag.
