Good examples Modern Museum! I tell people to practice all the time with the bundy tube first. Then duplicate your patterns into the stainless. Make sure the bender you use is designated to the tube size your bending.

Not true about double flaring everything.... Usally the S.S. in the aftermarket that comes in the spools is either a thinner wall tube or lower quality material and extra soft. Which is probably why you can double flare it ? I personally WILL NOT SACRIFICE A LIFE FOR A CHEAPER PEACE OF BRAKE LINE TUBING.

Good quality tubing you will only need to single flare. Just like it's always stated in ALL of these topics on flaring. "You need to crank hard to flare S.S. tube (not true)" Well if that's the case why double flare it ?

Yes the pricing isn't cheap for the good stuff, but what isn't ... And what's this all worth in the long hall in a car you just put your blood, sweat, tears, and MONEY into ? I think it adds an extra sense of security, resale sell value, and knowing it's your BRAKE SYSTEM and not an overflow tube.

I've been mixing the two ever sense I started plumbing. A lot of times especially in brake systems the two mix between SAE and AN. It's a matter of knowing when and how to make it work.

Not true about the flares... Think about it.... A flare is a flare(double single). It can be 10* 25* anything. As long as the two matting surfaces (male-female) are of the same angle you will have a perfect seal(which never happens) :idea: Also typicaly double flares are used on the softer mild steel tube to help strengthen the tube because it's to thin or soft to start with. So by folding over it self your thickening the tube. Where as S.S. tube is a harder metal (typicaly a thicker wall too) there's only need to single flare. If you tried to double flare S.S. at least the stuff I use and sell it will split.

Remember AN came from the military to speed up the process and the diversity on the vehicles. They were also using it on hydralics which is a really thick wall tube that only requires a single flare.

My best theory is over the years and the transitioning from the military into the automotive world with the mix of SAE 45* and AN 37* this will always be a mis-understood topic that gets way over anilized.

Do you sell those reamers ? If not what brand are they? Just so I understand correctly , you single flare 45 degree when using stainless line?
