OTC 4503 Stinger Double Flaring Tool Kit, Black

It works. Main tool jig broke on me so I had to buy another. You would think OTC would be lifetime warranty but it’s not. Only 1 year and replacement parts are 8 months out. Better options out there.

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.

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.

Couldn't find a double faring tool anywhere around me so I bought one on Amazon and was told it wouldn't work, well my car is back on the road and for me it was easy to use and did not have the problem with having burs or not being centered. No, I'm not a mechanic but do work on car's sometimes for over 30 years.

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.

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!

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.

Bought this tool to create double inverted flares on the hard lines for my Mustang project. I had to be very meticulous, but I had watched a good video on youtube which had a lot of good tricks. As long as I was diligent in following the steps, the flares came out fine. When I started getting over-confident and rushing, it would bring me back down to earth. I used it a lot, ran new lines for the master cylinder to distribution block, hard lines to the rear and along the rear axle, etc, and it lasted and is showing no wear or product defects. Very happy since it was only $25 bucks whereas the eastwood tool ran a couple of hundred (this was my first time doing this, so I was considering spending the cash for the eastwood tool, glad I didn't).

Muy buena herramienta.

Decent little flaring tool. Can be used for Inverted, bubble or 37 degree flaring. No leaks on the multiple projects I have used it on. Always make sure your flare matches the tube nut and seats properly and you shouldn't have any problems. A little oil or brake fluid as lube helps too when flaring.

Facile à utiliser

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