Stainless brake lines

[DKz Garage]

Looking for some input on stainless brake lines. I have the Eastwood flare tool, which seemed to make nice flares in the 3/16" stainless line... I know these can have leaking issues/ are a bear to get tight. Anyone have any experience using a single flair (37 degree) then using the collar and nut to seal with AN fittings?? Thanks in advance.

Single flare on stainless tubing with nuts and sleeves works fine for the pressure of a brake system. Single flare 37 degree AN fittings are not DOT approved. Some stainless tube can be double flared but most will crack during the flaring process. Tons of race cars, street rods, etc, use single 37 degree flares with the appropriate fittings and it works just fine.

Thank you for the input...not sure why I asked about AN fittings....thinking of the fuel lines. In any case....I was thinking it may be easier (less/no leaks) using a single flare/ 37 degree/ with the sleeves and nuts??

I've had really good luck using NiCop line and 37 degree double flares along with the sleeves and nuts. The NiCop is much easier to work with, doesn't corrode, and won't crack.
