Its forged alloy steel construction is designed for shop-grade toughness and wear resistance. This makes it suitable for frequent use on stainless lines while maintaining accuracy and repeatability in flare production.
Buying Guide
Key considerations when selecting a 37-degree flaring tool for stainless steel lines include compatibility with the target tubing material, the range of supported diameters, and the ease of achieving leak-free, consistent flares. Here are important factors to compare across options:
- Material compatibility: If you are working with stainless steel, confirm explicit compatibility for flaring stainless steel tubes, particularly 304 or similar alloys. Some tools are advertised for stainless, while others are best for copper, steel, or softer metals.
- Angle versatility: A tool that offers both 37° and 45° dies enables a wider range of flare types (single, bubble, double) across multiple applications, from brake to fuel lines and transmission coolers.
- Die sizes and tubing range: Ensure the tool supports common automotive tube sizes (3/16″, 1/4″, 5/16″, 3/8″). A multi-die setup simplifies handling different line diameters without changing components frequently.
- Mounting method: Vise-mounted tools provide stability and precision, which is especially helpful when working with stiff stainless steel tubing. Check for secure clamps and an easy dial alignment system to reduce misfi t risk.
- Build quality and durability: Look for heat-treated steel, corrosion-resistant finishes, and robust rotating heads. Durable construction reduces wear and preserves accuracy over time.
- Ease of use and safety: Clear instructions, safety precautions, and user-friendly operation minimize the chance of slips or misalignment, protecting both the operator and the tubing.
- Leak prevention performance: The best tools deliver repeatable, leak-free flares under test conditions. Consider user reviews or spec notes about flare integrity under pressure.
- Warranty and support: A solid warranty and accessible customer support help address any issues with dies or alignment over time, especially for professional shop use.
