Review on πŸ”§ Efficient OTC 6504 Deluxe ISO Bubble Flaring Tool Set with Cutter: A Comprehensive Solution for Precise Flaring by Jacob Schmidt

Revainrating 4 out of 5

Great tool for your money.

Great tool for the money even when bought at regular price! The tool is well made, works as it should, and is easy to use. With a little practice, I was able to make nearly perfect bladder expanders on a 4.75mm (3/16 inch) brake line. Deburring and beveling the end of the brake hose is a must to achieve good flares with this tool, but this step should be performed with any flare tool. The instructions are also well written. I originally wanted to buy a cheaper OTC 4504 Stinger Flare Tool but found it at a great price. Using lubricant (use brake fluid when flaring the brake lines) will help achieve better flaring.

Pros
  • Designed for metric steel brake lines where an ISO flare or bladder expansion is required
Cons
  • Hard to tell
