Buying Guide

Match tool to tubing size

Select a flaring tool rated for the tubing you work with (common sizes shown include 3/16" and 1/4") to ensure proper flare geometry and leak-free fittings

Double vs. 45° eccentric flares

Use a double-flaring tool for standard automotive brake lines and an eccentric 45° flaring tool for some copper or HVAC-style tubings as needed

Check included tubing and accessories

Kits that include brake line lengths, fittings, or adapters (for example copper-coated or copper-plated tubing and accessory packs) add immediate repair value and reduce extra purchases

Prioritize build quality and clamping stability

Look for robust clamps and hardened dies to maintain concentric, consistent flares over multiple repairs for safer brake joints
