MG MGA - Brake lines

I am restoring my engine compartment of my 1958 MGA 1500 and would like to know what the proper color is for the brake lines? I have cleaned one of them up and it is a bright silver finish. I guess these are steel lines. Just wondering how they came from the factory? If they are meant to be unpainted does anyone recommend clear coating them? Thanks.

If you use cupro-nickel lines, no need to coat with anything.

What is the likelihood that the lines I have are cupro-nickel?

Stephen Lofaro

Zero. Cupro-nickel pipes are sort of copper color, but someone who has seen them can easily tell they are not copper tubing. The silver color pipes are galvanized steel, as original.

So, did the galvanized steel lines go in plain and unpainted?

The first place I worked after leaving school (1965) was a factory making air braking systems for trucks. Mild steel components there were electroplated with zinc rather than galvanised. At that factory, the components were then "passivated" by dipping them in a chromate solution. This gave them a yellowish coloration.

Stephen, the lines I have bought from Moss have been cupronickel, mostly. They should have an etched marking "CN102" (UK) or ATM 706 in USA.
