cunifer brake lines -- anyone?

I saw this at the Leno garage website. Cunifer brake lines are a European concept -- originally from Volvo I believe. They're copper alloy lines that have some kind of plating.

They're supposed to be reliable and more flexible. Apparently they can be routed without bending tools. They're also supposed to be easier to flare and conform better to the other fittings.

Does anyone know anything about them? I've never had the nerve to flare ordinary brake tube because of all of the horror stories. It would be nice if this cunifer stuff would make this job easier.

All comments apprteciated, thanks

These guys have it ..

Along with a bunch of other things tubing related..

Looks cool, our local tubing supply guy has it, I have not used it, but a friend of mine has...he thought it was good stuff. 'Spensive though. It polishes up real nice.


Cu-ni-fer is an anagram for Copper, (Cu), Nickel,(ni),ferrous, (iron,Fe)
Kewl, eh.


later, mikey

interesting, and expensive. for anything other than rust prevention, and maybe the gold polish finish, i don't see it fixing anything. making flares in regular line is no problem.

Forgive the late intrusion but I came across this thread whilst looking for somehting else.

Long story cut short - the copper nickel alloy was developed as a solution to the problems of using copper pipe, which was in turn a solution to the problems of usng steel pipe.

Kunifer/cunifer tubing is widely used and widely available here in the UK. It's an alloy (not a coating) of mainly Copper and Nickel and I don't use anything other than this on my cars. Its easy to work with but its a solution to a problem that you may not have in some parts of the US. Our climate is very damp and I would guess the nearest that you can relate to is what you seem to call the 'rust belt'. In witer we salt the roads and steel brake lines rust through in a very short time, so does the rest of the car but that's another story. We started using copper brake lines as a way of combatting the 'tin worm' but found that they work hardened pretty easily and if subjected to vibration they would crack. Kunifer is stronger and doesn't work harden as easily but also doesn't corrode.

Hope that helps
