    Talking Re: corrosion around threads

    The new message board is less than 3 weeks old and we already have corrosion around the threads! What is the world coming to?

    Except those are not refrigerant lines, those are chiller lines.

    There is/was/has been leakage there, most likely at the top joint.

    Looks like 'newer' pipe thread tape.

    Probably 'was' leaking.
