Took awhile to get here but great tools from mastercool. I stripped the bubble (clamp) dies trying to do 3/8 stainless. It was .49 wall and way too thick. Should be able to handle .28 stainless. The does still work but leave marks on tubing now. Guess we’ll see how there warranty is.

Man, I use the heck out of these things! I bought them as an add on to complete my Mastercool flare kit. These things are great quality, never slip on the hard line and work on Aluminum, CuNi, steel, and even really hard Stainless steel. Prettiest flares you've ever seen! Just remember to put the nut and sleeve on first... and face the sleeve in the right direction too.. Lol...

The Mastercool kit is an addition to my existing Mastercool tools - brilliant tools to give a perfect finished result. The exceptional bit is that Amazon Prime facilitated getting this kit from Texas to Melbourne, Australia in four days and at a VERY good price! Amazon Prime has opened up a trustworthy international buying avenue for me I did not know existed. Well done.

I bought this kit to add to my 45 degree kit so I can also do 37 degree flares but I noticed you only need square dies and the 37 degree cone the silver plunger for all the sizes is the same 45 degrees plunger die that comes in any 45 degree set The silver plungers are 45 degrees (as shown in picture) The cone is 37 degree And all the square dies are 37 degrees (as shown in picture) So if you already have a 45 degree set you only need the 37 degree cone and the 37 degree square dies for whatever size you plan to do. Picture with all part numbers This kit fits any hand hydraulic. The kit is priced decently Quick and easy to make 37 degree flares It functions as any 45° set, just for 37 degrees Fast and easy to use

The actual tool was and worked as expected, it did a great job flaring hydraulic lines to connect to jic fittings. The only down side is that there is no case for all the pieces and there is no place to put them in the master set. So a case included would be a great asset
