Perfect doubles flares every time
I had also bought one of the cheap vice-held sets that wasn't fit for purpose. This, however, is a good quality item that produces perfect double flares every time. The grip holds the pipe firmly without damage and without needing to overtighten the nuts. The best thing is that all the critical settings, e.g. how far the pipe protrudes, how much the formers should be tightened down, are all controlled so no guesswork is required. Also, the formers are kept square to the pipe producing nice symmetrical flares - this is the big weakness with the cheap sets. Great tool and well worth the money.

Really well made
I used this to make up new brake pipes for my Mini Cooper S. For a hand held brake flaring tool it feels solid and really well made unlike some tolls I have used in the past. As its hand help I was able to use t to flare the pipes in situ, this really helped with the job, especially as the idiot (me) managed to damage on of the joining threads after the pip had been laid.

It works on steel (OE) lines
It does work brilliantly on steel brake lines as well, on the car so saves a lot of time, and quality wise its very nice, only down side to it is there's no case with the variant i got

Brake flaring tool
This is was my first attempt at replacing brake pipes. This tool made it really easy, created perfect flares on my first attempt. All installed with no leaks. Really good tool, highly recommend!

Great tool
Well engineered tool used on car to bubble and double flair worked a treat. Had to send 4 others different brands back as pipe just slipped back. This capri tool works great. Practice on bench first and if having to use on pipe on car plug pipe if you can and clean pipe to stop it slipping and you should be good.

Good tool
I tried this on copper nickel lines and factory steel lines. It worked well and produced clean flares but you need to make sure the body is clamped together tightly or it will produce misshapen flares. I would have liked to see it come with a case at this price.

Great quality brake pipe tool
Used cheaper sets that weren’t that great at producing quality flares but this is simple, easy to use and produces great quality flares also use if needed with out taking the pipe off the vehicle , bout sure what it’s like with steel pipes though as used on copper, great quality tool

Excellent tool
Easily creates double and bubble flairs. Used on brake line while still on car and worked perfectly first time on mild steel and copper nickle pipe. No sliding as firmly clamps pipe. Just take your time and don't rush.

Perfect flare
Perfect flare, easy to use. I found the nut was a little tight on the tube needed a little encouragement to slide back up to the flare. I assumed this is a me problem somehow. Perfect flare!

Precise, Easy to Use, Well Made
This tool worked superbly well! Creates bubble or double flare and is precise compared to the terrible clamp and yoke types I tried before this. The tool holds the pipe accurately, and the flaring bolt is designed to ensure the flare is centralised and correctly deformed without going off to one side to fail like those other tools did. Absolutely wonderful! It has opened up a new skill for me in creating new brake lines for my old vehicle.

Great tool and a time saver.
Feels and works like a German tool, even if it isn't. Easy to use. ISO bubble flare worked perfectly first try. Didn't have to chamfer the edge or anything. I can tell this tool could do many flares in the future. Buy it and don't worry about leaks.

Works great in tight places
The tool performed perfectly just as advertised. I had great flares first time everytime. Much easier to use then the old style of flare tool. This one just slides on the line to the stop nut you screw in clamp it down. Then you remove the stop nut screw in the #1 die run it down flip the die over #2 run that down and bam perfect flare everytime.
