Makes creating Flares foolproof. You can make practically any Brake, Trans, Fuel, or Coolant Line. Has almost every die & adapter needed. But doesn't come with the 2 dies & 2 adapters required for some GM model Coolant & maybe a Trans Line. That kit is the 72485. This kit is the 72475. All in all, it's pretty straight forward. As long as you follow the simple directions, you'll have the perfect type bubble/flare & it'll be Leak-Proof Too.... Just don't do what I ended up doing. I got side tracked and bought the 72475 Kit. What I should have got was the 72485 Kit. I mean I was actually working on a Pontiac Grand AM, ie GM.... I should have just sent this kit back because the time it took trying to see if getting those 4 extra parts through email-messaging the seller took longer than the return policy. So I was left ''Holding The Bag''.... Oh well, you learn right.. Still a quality tool & makes life way easier when replacing lines on vehicles.. I'd certainly recommend this product though. Mastercool is actually the best one made so for the investment, you'll be able to make a hell of a lot of lines, the right way, the first time.......

This master cool hydraulic flaring kit is phenomenal! It has so much versatility, makes flares, double flares, push to connect lines and making bubble flares a breeze. Early on when I got the kit, I was very frustrated with the fact that the T-handle does not apply enough clamping force on the dies to prevent the line from sliding out while initiating the hydraulic press portion of the tool. It was highly frustrating to the point where I was about to return the kit. However, I realized that the T-handle is removable (there’s a threaded knurled nut on it) so I removed it and opted to use a 13 mm shallow socket with a flex head ratchet to make sure I get that extra bit of torque to really clamp down the die. That’s the real trick with getting this kit to work. You just have to make sure the clamping dies are really tight, I just couldn’t get them tight enough with the T-handle so I used a 3/8 ratchet with 13mm to snug it just a bit more than you could with the provided T-handle, once I did that the tool worked perfectly! I’m a DIY guy. I’m not even a technician but if I were a technician, I would absolutely buy this kit. It is worth every penny and will pay for itself with one job. Just think about what it would cost you to pay a mechanic to do this type of job on your vehicle. You’re saving a ton of $$$.

I decided to start using marine grade stainless 3/16 tubing for brakelines on my vehicles. This flaring tool made it faster and easier than any flaring tool I ever used before. Stainless? No problem. No nicks, perfect pro flare every time. Nicer than the factory flare ends on store bought tubing. I also got a reamer to clean the ends. Very nice tool. My only regret is I didn't get this years ago.

Don’t buy the cheap stuff. This thing is legit! The flaring looks like it’s factory made. I definitely recommend it.

Seems like a nice quality product, But it does not come with directions or instructions on how to use. So if you've never used a similar tool before you may struggle to figure out the operation.

I can't believe I ordered this tool several years back but I only used it a couple of times knowing that as an owner of classic cars I would certainly use it one day. And I just did. Tonight's project was setting up and installing ends on stainless brake line for my 1983 Maserati Quattroporte, and if you know anything about them, they use combination standard and metric fittings. So on the 3/16" line I had to install both double-flared standard fittings and metric bubble fittings. Enter Mastercool. With little setup and prep I was making shop-worthy flares in no time, and the tool was effortless to use. A few pumps on the lever and the flare was done. Changing dies from flare to bubble and back again was done in seconds. Now I feel like going ahead and replacing ALL of the hard lines on this car and have far less dread doing what was typically a far more tedious job. Sure, it is expensive, but I certainly got what I paid for and heartily recommend this tool if flaring numerous brake lines is in your future. I would give it 6 stars, but even I have my limits.
