TOOLGUY REPUBLIC Adjustable Brake & Fuel Line Tubing Pipe Straightener - 3/16" - 1/4" Diameter Tubing

The only reasonably priced tool that clamps on to the tube so you can use it with lines that already have fitting on. It takes "working" the line, not just one pass, but it works well. I would recommend it.

A bit pricy for what it is, but it's cheaper and more complex than most on the market.It's not going to be straight with one pass through the tool, but a few passes and you get nice straight line.I'd say it doesn't do a great job with the first few inches (just the nature of the tool), but I got a 24 inch straight section of 1/4" SS line in just a few minutes.Happy to have this tool for future jobs!

With a little practice this tool does a pretty good job of straightening you break lines. I found that when your straightening your lines the curve needs to be down so when it passes thru the tool it straightens in an upward movement. A couple of passes is necessary.

Worked just as advertised... Takes a few passes but the more time you spend the straighter you can get the tube

As an owner of multiple automotive repair facilities, this product is essential if you are making brake lines. Gives a professional look for any brake line no matter the links that you are manufacturing. Highly recommend
