Wostore Single Flaring Kit 7 Dies 3/16–5/8" for Copper Pipe & HVAC — Heat-Treated Bar, Self-Centering Cone

The Wostore Single Flaring Kit is a compact, seven-die tool set that makes precise 45° single flares on 3/16"–5/8" tubing for HVAC, plumbing and automotive work.

This lightweight kit supplies a professional-quality flaring bar, a self-centering cone, and a T-handle yoke engineered to form clean, consistent single flares in copper, aluminum, brass and mild steel tubing. Built for both home mechanics and field technicians, the tool fits seven common outer diameters so you can prepare tubing ends quickly and reliably for low-pressure fittings and flare connections.

How does this kit make flare work easier and more accurate?

The kit combines a heat-treated flaring bar with a self-centering cone and an ergonomic T-handle to reduce slippage and operator fatigue. The self-centering cone aligns the tube automatically, producing even 45° flares and minimizing rework.

• Heat-treated flaring bar resists wear and holds tubing firmly.
• Self-centering cone prevents off-angle or uneven flares.
• T-handle lever delivers controlled force with less effort.
• Seven dedicated dies match common O.D. sizes for precise fit.

What tubing sizes and materials will this set handle?

This set includes dies for 3/16", 1/4", 5/16", 3/8", 7/16", 1/2" and 5/8" outer-diameter tubing, covering the majority of HVAC, plumbing and automotive low-pressure lines. It works with copper, aluminum, brass and mild steel.

• Die range: 3/16"–5/8" O.D. (7 sizes) for common tubing.
• Suitable materials: copper, aluminum, brass, mild steel.
• Designed for low-pressure flare fittings and sealing applications.
• One kit replaces multiple single-size tools for convenience.

Will the flares seal properly and avoid leaks?

The tool forms consistent 45° single flares that mate cleanly with standard flare fittings when tubes are prepared correctly. Properly formed flares reduce the chance of gaps and allow compression fittings to achieve a reliable mechanical seal.

• Accurate 45° angle matches standard flare fittings.
• Even flare faces prevent uneven compression and leak paths.
• Firm clamping and centered forming reduce metal thinning.
• Works best on clean, burr-free tubing ends for optimal seals.

How durable and portable is the Wostore flaring kit for field use?

Components are heat-treated or built for daily use so the set withstands repeated clamping and forming without rapid wear. The compact footprint and simple components pack easily into a technician’s bag or service box for on-site repairs.

• Heat-treated bar for long-term strength and straightness retention.
• Compact, lightweight design for easy transport and storage.
• Simple assembly and manual operation—no power needed.
• Corrosion-resistant finishes extend service life in workshops.

Who is this for? Technicians, contractors and DIYers who install or repair refrigeration, air-conditioning, plumbing or automotive low-pressure tubing will benefit most from the Wostore Single Flaring Kit. It’s suited to anyone who needs a portable, reliable tool to create standard 45° single flares across the most common tubing sizes, whether for routine maintenance, emergency field repairs, or workshop projects.
