### ⭐⭐⭐⭐⭐ A total winner.
*by A***Z on June 5, 2017*

The shipping company had some delay on the road. Since I had a long weekend available to replace my brake lines, I couldn't wait for the shipping issue to resolve itself.I bought a more expensive set at NAPA. I'd resolved to send this one back.Gathering all my Popeye-ness, I doggedly made up endless double flares. After a while, the NAPA set began to crack at an eye, admittedly, getting a lot of stress.In time, I just had to return the locally purchased set.By now, this set had arrived.NIGHT and DAY better set.The threads are finer. You don't need quite so much Popeye.The flares seemed to come out cleaner (given that I was new to double flares and I'd gained experience and had developed a bit of a method).The transitions from one process to the other was easier.This unit is better designed, appears to be better materials and had no breakage.The tube cutter isn't as good as any of the Rigid cutters I have. I ended up using one of my own.Something I realized, it is often stated that the tube ends need to be cut square, de-blurred on the inside of the tube, beveled inside and out.It should be easy to cut square with any of the tube cutters.Practice, if you're new to double flares. But, a wonky flare may not be due to a out-of-square cut. I believe you can get the same result if your outside bevel (I filed mine) is not even all the way around. If you have a segment of the tube end with a thicker wall, after you bevel it, I do not think you can force it square in the flaring process. Just too much material.Watch the end thickness as you bevel the outside. Get it pretty close to even all the way around. Then de-burr/bevel the inside.Great set, gerat price. Nice case.A total winner.My truck even stops now!

### ⭐⭐⭐⭐⭐ Worked perfectly on .032 copper ACR tube for double flare.
*by C***K on March 1, 2022*

This is my experience. I am not a professional mechanic (I am an engineer), so it's application to your specific problem or my method may not be correct for your application.. The results for my application were excellent executed as I describe. You must choose appropriate tools, lube, tube, cleaners, fittings, and components for your specific application. There are safety regulations that must be investigated and followed to be legal. My federal marine fuel line regulation required a min. of .029 tube wall, so Cupro Nickel .028 lines locally available at auto parts places could not be used, I ordered appropriate approved copper line here on Amazon.I remade a damaged copper 5/16" fuel line with 5/16" soft copper tube (.032 wall) and 1/2" 45 degree brass flare nuts. Results were excellent. Completed flare was actually slightly more uniform than the original. This set of flare tools appears solid and sturdy if used correctly. In the photo above is a freshly made flare right out of the die (before I dusted off a stray burr sitting there loose with a copper cleaning pad. The pipe was cleaned and burr removed immediately after. Always inspect and clean off stray dust and particles before connecting.For those who have difficulty making good flare joints, the secret is all in the careful preparation. Once it's prepped with care, the rest goes quick and easy.Here's thoughts to help:1. Keep the tool clean in its case when not in use and dirt and grit free. Get the right tube for the job that complies with regulations. Where possible, make sure you work on a straight section. Install the flare and nut before bending if working close to the flare. Use a good bender. I purchased one here for 5/16 tube. Follow directions for the specific tube; most guides say to anneal hard copper tube with a torch. Soft is easier and good to go without annealing.2. Cut your tube to length using the tubing cutter gently to minimize distortion. Do more turns less pressure. Avoid a saw, but at least do not cut crooked!3. Chamfer the tube with a good chamfering tool. The rigid tool I purchased on Amazon is particularly good in my test: "RIDGID 29983 223S Stainless Steel Pipe Reamer, 1/4-inch to 1-1/4-inch Inner/Outer Reamer". It has many small cutting faces vs just a few on cheaper ones; so makes a very uniform smooth cut.4. Now you can clamp it up being very particular to follow published guides for the stick out past the tool. Get a good tight uniform hold. Double flare sticks out exactly the height of the die piece. Look at good instructions or watch a good video.5. I now lubricated the double flare die. I used some high zinc motor oil I had handy for my marine engine. Tiny residue won't harm a gasoline carburetor. For brake lines, use only an oil compatible with your brake system or be prepared to clean it perfectly in solvent. Extreme pressure grease seems a good choice for hard to flare tube only if you thoroughly solvent clean after. The lubricant decreases the force necessary to flare smoothly. Avoid getting it on the clamp surfaces that grip the tube. If you do, clean with suitable solvent. On thumbscrew threads lube is fine, where friction is king holding the tube, don't use it. I tend to clamp tight, which reduces risk of slipping, which does leave a slight harmless pattern on the tube wall.6. Once lubed, well gripped, and perfectly concentric, it will produce a good solid flare. I had no trouble going slowly and making repeated good flares. Good means a good clean uniform seating face with a nut that pulls it in straight.7. Once the edges are chamfered slightly inside and out, check each end visually and remove any burrs with a copper cleaning pad. Point down while you do this so nothing falls in. Leave nothing to cause trouble. As an extra precaution, with no compressed air handy, I dropped a string through the tube, and tied a small piece of copper cleaning pad on, and pulled it through. This clears loose flakes or burrs out of the tube.8. Practice is a good thing. I made a couple of test double flares. Including one I lightly coated with a dusting of spray primer and snugged up in the filter inlet a little; then rotated back and forth several times. I then unscrewed the nut and inspected the mating faces to ensure they were mating properly over 360 degrees. You can see the impression because of the coating. There are special testing dyes sold for this which are more appropriate. I cleaned the surfaces with acetone after testing to leave no residue.9. Basically that is the way to success. Prep everything carefully. Make sure everything is straight concentric and smooth. Lubricate dies appropriately after clamping. Clean your work, check your work. Finally, after installing, leak check under full pressure. (use a flare nut wrench designed for tubing too...this minimizes the risk of rounding off or distorting a nut when tightening. Flare nut wrenches grip the nut face all around except for the tube gap, not just two faces). My creed is check your work at every step, and then do a final test. Every once in a while you still get a surprise when something just doesn't behave even though you thought you nailed it.That's it. For my app, with copper tube, set worked perfectly and still looks brand new on completion, so that's an A+.

### ⭐⭐⭐⭐⭐ Professional grade.
*by V***S on June 29, 2025*

There's quite a lot of low quality flaring tools on the market that will frustrate you with crooked flares, or even just outright break in use. This is not one of those tools.
