In the UK there are basically two types of approved automotive
hydraulic tubing.
The first is the normal steel tubing used as standard which is
sometimes called Bundy Tubing probably because it was made
by a company called Bundy?
The second is an after market tubing called Cunifer which is a trade
name for a copper/nickel tubing. It is designed for automotive brake
and fuel lines, is widely used for repair work and is approved by our
MOT inspectors.
I do not know what it is called in the US but I have used Cunifer in
many projects, it is harder to flare than steel but does not corrode
and has a higher burst pressure than steel or copper.
