I must change rusted oil cooler lines (from tranny to cooler), so does anyone knows, what material i must buy (copper isnt good solution, i think). I find steel lines (plated with copper inside and outside). They hold pressure up to 180bar - is it enough?
:hmm:

Steel lines should be good enough. I'm not sure about the copper coated lines though....? What would be the reason for using that?

Thanks, lux hauler - they are some sort of brake lines. I didnt find here plain steel lines.
