Review: Very good product - Worked great for flaring brake lines
Review: Worked great - I used this to replace a ruptured brake line on my 2007 Mercedes. Worked great!!! I made one test crimp and realized that I didn’t compress it enough. The next two were perfect and haven’t had any leaks in two months of use.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very good product
*by B***T on 10 August 2026*

Worked great for flaring brake lines

### ⭐⭐⭐⭐⭐ Worked great
*by M***R on 18 February 2025*

I used this to replace a ruptured brake line on my 2007 Mercedes. Worked great!!! I made one test crimp and realized that I didn’t compress it enough. The next two were perfect and haven’t had any leaks in two months of use.

### ⭐⭐⭐⭐⭐ Works well, if nuts are tightened enough.
*by A***N on 18 July 2026*

Does the job well - used this to replace a large amount of brake lines and successfully used it to produce bubble flares which have a good seal. Be aware that you need to use pliers or a wrench to tighten the locking nuts otherwise the pipe will slip through as you tighten the die. Leaves some marks in the pipe but nothing major.
