Review: Great so far! - I’ve only used the straightener a couple of times so I can’t speak on the durability but it’s weight and feel make me thing it’ll last a long time. I’m amazed how well this tool straightens tubing. Once you get the tube through the tool, straightening is a breeze as all you have to do is pull it back and forth a few times. I was working with stainless steel and very happy with the results. This is a must for anyone who’s using coiled tubing for brake lines.
Review: Great tool. Quick easy and simple. - Great tool! Working on a Trail Buggy and running all hydraulic lines requires buying coils of 3/16 tubing. Uncoil, pass through the tool, and slide it back and forth a few times for perfectly straight tubing. This little tool fit in my flaring tool bag. It is lightweight and maneuverable even under the car! Professional results.

## Questions & Answers

**Q: How do I check if the tool is suitable for my pipeline/coil?**
A: The dimensions described on the page (3/16'', 1/4'', 3/8'', etc.) are the maximum outer diameters that the tool can accommodate. So please measure the outer diameter of your pipe/coil first.

**Q: Is this hand tool laborious?**
A: It depends on how hard or soft your pipes are. The small size of the soft tube can be held directly with one hand and easy to withdrawn with the other hand. If it is a large, rigid pipe, it may need to be straightened a little from the inlet end.

**Q: Why are my pipes so hard to straighten?**
A: The following reasons can be considered for analysis: 1. Pay attention to the pipe opening not to deform outward (such as flaring); 2. The pipe is severely bent (such as a 90-degree bend); 3. The pipe is too hard.
