Thorstone Single Flaring Tool & Swaging Kit
The Thorstone kit is designed for single flares and swaging on copper, aluminum, and brass tubing, with a 45-degree flare. It includes two flaring bars sized for common O.D. tubing (1/8″ to 3/4″), a flaring cone, a tube cutter (1/8″–1-1/8″), five swaging adapters, and a ratchet wrench. The set is built with heat-treated steel components for strength, with a chrome swivel to reduce friction. It is not intended for hard materials like steel, iron, or other non-soft metals.
This tool is well-suited for standard HVAC refrigerant lines and automotive brake lines that require precise 45° flares in softer tubing. The included case helps keep everything organized for field work. Users should ensure correct alignment and sizing before applying pressure to avoid imperfect flares.
Wostore 7 Dies Flaring Kit
This kit provides seven dies for eccentric flares across 3/16″ to 3/4″ copper tubing. It emphasizes precision with a simple clamping screw and a large feed screw handle to minimize effort. The dies enable accurate 45-degree flares, making it a strong choice for refrigeration, HVAC installation, and plumbing tasks where consistent flare geometry matters. It is especially helpful for keeping flare walls uniform across various tubing sizes.
Super Stars 5-in-1 Flaring Tool Kit
Super Stars’ 5-in-1 kit is designed for 45° single flares with a robust, large feed screw handle to ease operation. It features precise locating through a steel locating bar and holes embedded in the yoke. The clamp supports both metric and imperial measurements (1/4″, 5/16″, 3/8″, 1/2″, 5/8″, 3/4″; and 6mm, 9mm, 10mm, 12mm, 16mm, 19mm). It is commonly used for R410A refrigerant work on copper, brass, aluminum, and mild steel tubing.
Super Stars 1/4″ – 3/4″ Flaring Tool
This compact single-flare tool from Super Stars provides precise locating and dual clamps for metric and inch sizing. It covers 1/4″ to 3/4″ tubing and is recommended for R410A flare applications in soft copper, brass, aluminum, and mild steel tubing. The design emphasizes ease of alignment and consistent flare walls, making it a practical choice for field service and shop work alike.
Buying guide: Key considerations
- Flare type and compatibility: Ensure the tool creates 45-degree single flares (not designed for double flares) and supports your tubing material (copper, brass, aluminum, mild steel).
- Diameter range: Check the OD or ID range covered by dies and bars; consider future projects to avoid frequent tool changes.
- Build quality: Look for heat-treated steel components, chrome or alloy swivels, and robust yokes to withstand repetitive use.
- Ease of use: Large feed screws, ergonomic handles, and clear alignment marks reduce effort and improve flare consistency.
- Portability and storage: A case or organized components help with transport and field work; consider weight if you travel to jobsites.
- Power source (for electric models): If choosing a cordless tool, verify battery capacity and expected flares-per-charge to meet job demands.
- Included accessories: Cutter tools, swaging adapters, and limit/clutch features can streamline workflows and reduce rework.
- Maintenance: Regularly inspect dies for wear and replace worn parts to maintain flare accuracy and prevent leaks.
