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?

Re: corrosion around threads
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.
