    How can you tell besides the color? I found a model for the suction side. It is ep13bz241. But I couldn’t find any information on it online since it is a replacement part for a carrier valve.

    Copper is too soft.

    Why do you ask?

    Whether or not to use flux while brazing in the copper line set

    It looks like the liquid line slowly turns to copper at the end but Idk how that could have been done.

    I believe they're plated so that you can braze them with normal rod.
    But I've had a few issues that made me think maybe I should have put some flux

    Similar to how they plate the connections on a filter/drier with a steel shell.

    Using flux on copper is always fine and can be superior even with sil-phos.

    If you're not sure, use flux.

    You could also use fluxed rods.
