Brake line flaring tool?

[blee03]

SE Michigan huh? So am I. You can borrow my flare tools if you want to...

No issue. You'd cream your pants if you walked in my shop. I have more machine tools and hand tool than I'll ever need.

Are you talking to yourself here?

Lisle makes a nice double flare tool, I use it quite often to make brake lines.

I couldn't find the answer to this anywhere. So, is NiCop (brand) tubing 90/10 or 70/30? 90/10 is the cheaper and weakest of the two.
