Review: This kit 72475 is missing 4 parts 4 GMs. That's the difference between this Kit & the 72485 Kit. - 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.......
Review: FANTASTIC BIT OF KIT! - 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 $$$.

## Questions & Answers

**Q: Does this have the gm 3/8 and 1/2 transmission line dies included? It is supposed to in this kit but the picture doesn’t them. not said in description**
A: This kit is 72475, which does not include the Jiffy-tite transmission line dies. 
The kit that includes them is 72485.

**Q: will it do 316 stanless steel tubing**
A: Hello 
The 72475-PRC is designed to work on softer metals  such as "Annealed" or "Dead Soft" type stainless steel.  Thank you.

**Q: The relief valve broke on mine. Anyone know where I can get another relief valve assembly? Thank you.**
A: You can call Mastercool at 973-2529119. You can get an RGA to send the unit back in for repair or order hydraulic repair kit.

**Q: Do you have to chamfer the edges before flaring?**
A: A slight chamfer is best to get a clean flare, but not too much, you don't want to take away too much material. You just want the edge free of burrs. Use a 32 teeth per inch hack saw blade if you are not using a pipe cutter. The better the prep, the better the flare.
