Stainless steel brake line

It’s not easy to get because it’s not very good and no one wants to use it, and is difficult to work with to the point of being dangerous.
It tends not to come on rolls though, only in straight lengths.

The more you think about it the worse it becomes as a choice of material. Something hard and brittle is not a good material choice no matter how pretty it looks.
I’ve had to work with it a couple of times and I’d never use it on my own vehicles or ever recommend anyone else use it either.

I've used the ATE green coated steel line that looks the same as the oem line on most European vehicles, not too bad to work tbh, a cheap pipe bender and a sykes flaring tool does a nice job, used 10m of the stuff on a friends sprinter, looks original!

whenever possible i reuse the original unions as they are far nicer quality than anything I've found aftermarket, i have a tub of spares from scrapyard visits as so many are the same, good pair of snips in your pocket gets a good amount quickly

Agree with Dez, It's a very poor material choice for brake lines.

Eastwood used to sell it in rolls, and in line with everybody else, I concur its a heinous stuff to work with, I have done 2 cars with the stuff, and probably wont use it again, its a sh-te to flare as its so hard. but I don't think its brittle, I personally think pure copper lines would be more likely to fatigue and break than the stainless would.

There was an article in one of the mags a while ago about not using copper, because it can fracture under vibration, and how cunifer (k?) was much better.
TBH I couldn't really see the argument, I've never had a line vibrate to the point of fracture in all my years of fiddling with brakes, and surely you should have it correctly supported anyway?
