Being able to make fuel line and transmission line connections is a bonus too. So far it has performed flawlessly on everything I have used it on. Inverted double flares come out perfect with no worries about leaks. Granted I have not used every fitting and adapter it has yet, but I did play around with some of the ones that I have not had a call to use just to verify it would indeed make the proper ends without any trouble. Being a mechanic since the late 1980s, I have seen all sorts of shade tree hatchet jobs on transmission, power steering, and even brake lines over the years. Most of the time it is because they did not have the proper tools for the job and/or did not know any better. Compression fittings are fine for non-critical, low pressure use but I would never trust such a fitting in a brake system that has to work in emergency circumstances with pressures over 1000psi. I have seen many of these develop leaks over time and have heard of them blowing apart. I have even seen a brake butcher job where someone tried to use just a single 45 degree flare to join the lines. Thankfully they could not get it seal off and brought it to me to fix it properly. Before this tool, I would just buy lines in predetermined lengths as close to what was needed as possible and bend them to shape and try to make sure any excess was safely out of the way somewhere or buy line with the correct bends already in place. Now, thanks to this tool, I am no longer confined to those two choices as I can make my own lines the exact length I need without worrying about the ends. I have seen numerous PS & transmission lines patched with rubber hose over the years that often leak later because people just slide the hose right up on the smooth metal line. Eventually the hose slides off because there is no flare for a clamp to hold against. This tool solves that problem too. Just use the fuel line fitting dies but do not crimp them all the way. About 3 to 6 pumps (depending on the line) after all the slack is out of the tool will leave a nice rounded bubble flare in the line that doesn't have any sharp edges so a hose can easily be pushed over it but have enough flare to keep the hose clamps from allowing the hose to slide off over time. It may take a bit of experimenting to get the proper size bubble in the line. I have included a picture of such a bubble & the fuel line flare that results if you go until the tool stops. The included tubing cutter is the small type intended for close quarters and works well enough. I would advise buying a dedicated tool for reaming/deburring your lines after you cut them. The case is also a decent case with an actual hinge & decent clasps to hold it closed. Not just a thin plastic strip hinge that always cracks after a few years leaving you with a box that no longer stays closed & loses components. If you regularly work on automobile hydraulic or fuel lines I would say buy this tool. The only thing that would make it better is if you could buy it with the 37 degree dies for AN fittings already included with these instead of having to buy them separate. Review: You won't be disappointed - The best and only flare kit you will ever need to buy. Almost every shop I have worked in had one of these for making power steering lines, transmission lines, and of course brake lines. The only time I've had to redo a flare with this tool is when you forget the fitting! Now working in a shop without one and doing work at home I finally made the purchase to do brake lines on my own vehicle. Everything fit nicely in the case, and everything is of high quality material. ## Features - This kit fabricates: push connect 1/4, 5/16 and 3/8" - Gm fuel Line Flare, Brake Lines and transmission 5/16 and 3/8" - Flare/double Flare 3/16, 1/4, 5/16, 3/8 and 1/2", metric bubble Flare 4.75, 6, 8, and 10 mm, GM transmission cooling Line 3/8 and 1/2 - Comes with tube cutter - Comes in custom molded box ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06WD86RLH | | Assembly Required | No | | Best Sellers Rank | #302,256 in Car & Motorbike ( See Top 100 in Car & Motorbike ) #67 in Brake Pipe Flaring Tools | | Brand | Mastercool | | Colour | Silver/Blue | | Customer Reviews | 4.7 4.7 out of 5 stars (549) | | Date First Available | 27 October 2017 | | Exterior | Structural body is Metal | | Generic Name | Universal Hydraulic Flaring Tool Set (3/8"&1/2" Transmission Cooling Line Die/Adapter Sets Plus Tube Cutter) | | Item Dimensions LxWxH | 35.6 x 30.5 x 10.2 Centimeters | | Item Weight | 5 kg 440 g | | Item model number | 72485-PRC | | Manufacturer | Mastercool | | Manufacturer Part Number | 72485-PRC | | Product Dimensions | 35.56 x 30.48 x 10.16 cm; 5.44 kg | ## Images ![72485-PRC Hydraulic GM Transmission Line Flaring Kit - Image 1](https://m.media-amazon.com/images/I/71FrOxWv16L.jpg) ## Questions & Answers **Q: Whats the warranty** A: THE HYDRAULIC PUMP COMES WITH A FULL 1 YEAR WARRANTY. THE ADAPTERS AND DIES COME WITH A 90 DAY WARRANTY. **Q: Free returns? states "free returns" when viewing item on my android .** A: Yes **Q: What the vest way to anneal the stainless steel. To a softened state?** A: Annealing temperatures stainless steal depends on whether it is magnetic or nonmagnetic, the temperatures are different, the additives to make it magnetic or nonmagnetic will determine the temperature at which it will anneal. When you find what metal is added to the stainless heat it to that degree and then air cool. Never quench after heating or you will make it hard. **Q: what kind of line material can i use? Copper, Steel?** A: This tool will easily flare copper or steel. Copper is not approved for brake lines. There is a copper looking alloy available that is very easy to work with. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Professional quality tool delivers professional results. *by J***S on 8 February 2022* I bought this in preparation for doing some brake work on several different vehicles where I would be making my own lines.
