Tried it out as soon as I got it. Seems to work real good, clamps onto tubing well, not like other ones I tried.

I purchased this kit for making double flares in automotive brake lines (some copper, some steel). I was really impressed by this tool's consistency with copper tubing, and was even more surprised at its ability to make a proper flare in old steel line. Quick notes:-Tighten the end FURTHEST from your line first, then tighten the closest one.-Copper line is easy to do by hand, but steel lines will take more effort. You won't be able to tighten the main shaft enough to flare by hand. You can use a wrench or a hollow tube to make the handle longer for easier rotation.-In buying a less expensive tool, you compromise ease of use. If you want something quick and efficient, there are better tools that are more expensive. If you don't mind putting in extra effort, you can get great results in a short amount of time.Overall very pleased with this tool. Used it for brake lines on two cars (one with steel lines, one with copper) and haven't had any bad seals from flares.

The product is inferior and cheap should have known better took a chance reading all the reviews and they're very misleading. This product broke my first attempt very disappointed, really disappointing part is you have to find who owns this company to get a replacement part you get a run around in the bunch of circles and you just end up set up for a return. Every manufacturer or company that I have purchased items from has a contact number information so that you can get parts and services there is nothing with this part you have to do the research you have to find who owns this company, tired of being run around in circles it's kind of sad There are two or three different companies connected to this part at least that's the run-around that I've been getting so if you have a problem I told you so. I would spend the money on something a little worthwhile a little more trustworthy I have no problem with paying more I should have. All I needed was a 3/16 cast size of a dime probably the same cost and I can't get it. Don't buy this product don't let the price fool you you get what you pay for. Instead of me finishing this project it'll be on hold until I can find another 3/16 flaring tool, can't put a price on that.

I bought this tool to replace the brake lines on my RV which had corroded from age and too many trips up north. Although I had over 20 flares required to complete the job, I couldn’t bring myself to purchase a high end hydraulic tool. However, I also wanted something decent quality since I knew the project would take several days to complete. All I can say is I am blown away at how easy this tool was and how well the flares turned out. In all my attempts (including a few extras when I forgot to install the nut first) I had only a single flare come out uneven. All the others came out perfect on the first try. When I finally got the whole system plumbed back up and connected there wasn’t a single leak! If you’re in doubt, go ahead click buy it now cause you won’t be disappointed!

Works very well if used as instructions. I have been using a kit like this one for over fourty years. The first one in a auto repair shop on only steel brake line. We cut the line to the proper length, and flare it with a double flare it. WE never had a problem with leaks that I remember. That work just like this one. Deburr your tube inside and out side. Don't over tighten your tube clamp bar. This will egg shape the tube, and give you a bad flare. Make sure tube is cut straight, or you will also get a off center flare. This kit works really good for me. I used two other kit Like this one. Straight, deburr, and don't over tighten clamp. Take your time, check your tube straightness, by putting it at the top of your tube clamp bar, other wise you can spend $200 + for a rotating one. I never used one, & I buy rolls of brake line, & bags of fittings.

Not the best I have ever used, but finding a good quality flaring tool nowadays is pretty tough without going really high end. This will get the job done though and the price is decent. They tend to leave the flare a slight bit off to one side, but so much that it is unusable. I have performed about 25-20 flares and none have leaked yet (finger crossed that it stays that way). Of course, when flaring, I personally do not finish the inverted flare all the way, I leave it a bit uncompressed so that when I install the end, the flare can some play to crush and form to the union/receiving hose, etc. and seal the connection better.

Package came faster than expected. Very impressed. And the quality of the product is also very impressive. The case it comes in keeps everything together. (Nice.) After making a couple of trial flares I was able to make good quality double flares quite easily. I looked online and in stores and I believe this is extremely good value and quality for the money. Impressed and highly recommend!

Bottom-lie up front: If you are an occasional user of mild/light steels or metals, this kit is okay. If you are dealing with Stainless Steel tubing, this is NOT what you want.I bought this tool to repair a blown-out brake line on my 14 year-old truck. I also purchased a spool of zinc-coated steel tubing and fittings to do the job. Anyhow, I was able to make decent flares with the mild-steel tubing. One problem though is that when you gronk the clamp down onto the tubing, the two halves of the clamp piece are not exactly lined up perfect, which can affect the accuracy of the flare. After completing the repair, I ordered SS replacement (pre-bent) lines for the whole truck. One of the lines simply would not feed through the little nooks and crannies in one piece so I decided I would cut it at a convenient spot, feed it through, then splice the ends together with my flaring tool. The flare tool did not work, and after removing the tubing from the clamp I realized that the SS tubing flattened all of the gnurling on the clamp such that it will no no longer hold even mild-steel tubing tightly to make flares. So now the clamp is trash, at least for 1/4' tubing. I will note that the box does say inside (very small print) that it is for mild/light metals, so it is pretty much my fault. Otherwise, this is a pretty decnt tool. It got me out of a jam, so I was pretty happy, just perturbed that it wasn't strong enough to do stainless.
