Ease of Use
Since I planned to use the tool frequently, I prioritized ease of use. I looked for features like ergonomic handles and simple operation mechanisms. I found that tools designed with user-friendly features made the flaring process smoother and more efficient.
Compatibility with Pipe Sizes
Different mini split systems require various pipe sizes. I made sure to check the compatibility of the flaring tool with the specific pipe sizes I would be working with. This step was crucial in ensuring that I wouldn’t run into issues during installation.
