Buyer’s Guide: What to Consider

Choosing the right flaring tool depends on your project needs. Consider these key factors to make an informed decision.

• Flare Type Compatibility: Classic cars typically use SAE double flares. Ensure the tool creates double, single, and bubble flares if you need versatility.
• Tubing Material Support: Check if the tool works with steel, copper, or nickel-copper. Stainless steel requires specialized tools, so confirm before buying.
• On-Car vs. Bench Use: Compact tools allow in-place repairs, while vise-mounted models offer more precision but require a workshop setting.
• Size Range and Dies: Most kits cover 3/16 and 1/4 inch, but some include larger sizes. Choose based on the tubing you plan to use.
• Build Quality and Durability: Look for hardened steel or forged construction to withstand repeated use. Corrosion resistance is a plus for longevity.
