FORSUN Flaring Tool Set for Tubing — 6 Dies 1/4–3/4in 45° Flares with Hardened Chrome Bar and Large Feed Screw

The FORSUN Flaring Tools Set creates precise 45° flares in soft copper, brass, aluminum and mild steel tubing for reliable, leak-minimizing connections.

This compact flaring kit supplies six die sizes—from 1/4" to 3/4"—and a hardened chrome-plated flaring bar designed for workshop and field use. Built with a single clamp screw and large feed screw handle, the tool makes single and double flares quickly while resisting wear. It’s suited for brake lines, fuel and refrigeration tubing, plumbing repairs, and general metalworking where a clean, repeatable flare is required.

How does this tool make flaring faster and more consistent?

The FORSUN flaring set centers the tube in heat-treated dies and uses a robust feed screw to drive an eccentric cone, forming a controlled 45° flare. The single clamping screw with a sliding T-bar handle secures tubing without slipping, reducing rework and uneven flares. Consistent alignment and a smooth turning handle cut cycle time and effort compared with improvised methods.

• Six precision dies covering 1/4", 5/16", 3/8", 1/2", 5/8", 3/4" tubing sizes.
• Hardened chrome-plated flaring bar for durable, repeatable flares.
• Large feed screw handle for easy rotation and controlled force.
• Single clamp screw and sliding T-bar for firm, fast clamping.

Which materials and applications is the kit best for?

This tool is optimized for soft materials—copper, brass, thin-walled aluminum and low carbon steel—commonly used in brake lines, refrigeration, fuel systems and plumbing. It forms neat 45° flares that fit standard fittings, reducing the chance of leaks when installed correctly. Avoid using on hard, thick-walled steel without confirming material compatibility.

• Ideal for automotive brake pipe repair and fuel lines.
• Suitable for refrigeration and HVAC flares on approved tubing.
• Works well in plumbing, light metalwork and workshop maintenance.
• Not intended for heavy-duty hardened steel tubing without testing.

What features improve durability and user comfort?

The flaring bars are heat-treated and chrome-plated to resist deformation and corrosion, keeping jaw alignment accurate over time. The eccentric cone mechanism combined with a smooth large-diameter feed screw reduces hand fatigue and allows controlled formation of the flare. These design choices extend tool life and help maintain consistent flare geometry across many uses.

• Heat-treated, chrome-plated bar for long-lasting strength.
• Eccentric flaring cone delivers even 45° angles.
• Ergonomic feed screw and T-bar for easier operation.
• Compact kit footprint for workshop storage or mobile use.

How do I choose the right die and avoid common mistakes?

Select the die that matches the tube outside diameter to ensure proper flare seating and leak-free fittings. Cut tubing square, deburr the inside and outside edges, and clamp securely before flaring to prevent cracks or uneven lips. Test-fit the flared end with the intended fitting and, if necessary, reflare rather than over-stressing the metal.

• Match die size to tube OD: 1/4"–3/4" range included.
• Always cut tubing square and deburr before clamping.
• Clamp firmly with the T-bar to avoid slippage during forming.
• Inspect flared lip for cracks; replace tubing if damaged.

Who this is for: technicians, DIYers and professional tradespeople who need a compact, reliable flaring solution that covers common tubing sizes. If you work on automotive brake and fuel lines, HVAC/refrigeration piping, domestic plumbing, or small-scale metal fabrication, this FORSUN kit offers durable construction and straightforward operation for consistent 45° flares. It’s a practical addition to a garage, service van or workshop toolbox.
