TOOLGUY REPUBLIC Adjustable Brake & Fuel Line Tubing Pipe Straightener - 3/16" - 3/8" Diameter Tubing

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!

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.

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.

Not good for stainless tubing. Hard to fit in areas. Tried it in copper on a bench with it supported by a vice and still not good.Only intended to get very minimal imperfections out of tubing not for straightening.

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