NiCopper brake lines

Once you use that line you will never want any other kind ever again. Very easy to work with
and last longer than any of us will ever live. It should be a law that all vehicles should use copper nickel just for safety.
I have had wwII military trucks that still had every factory installed brake line on them with no sign of needing replaced. That's nearly 80 years, they will not rust. Easy to seal.
