Understanding Double Flares
Before diving into my recommendations, it’s crucial to understand what a double flare is. A double flare is a specific type of fitting used in brake lines, which provides a safer and more robust connection compared to single flares. I learned that this is particularly important because brake lines are under high pressure, and any leaks can be dangerous.

If you’re looking for something that requires less physical effort, a hydraulic flaring tool might be the way to go. I found these tools to be more efficient, especially when working with harder metals like stainless steel. The hydraulic mechanism provides consistent flares, which can save a lot of time.

Make sure the tool you choose is compatible with the sizes of brake lines you plan to work with. I often work with both 3/16″ and 1/4″ lines, so I was keen on a tool that could handle these sizes without any issues.
- Portability:
If you’re like me and often work in different locations, consider the tool’s portability. I found that compact designs are easier to store and transport, which is a bonus if you’re working in tight spaces.
