What is light green 1/2" threated piping used for?
I know that black piping is used for gas. I know that non-color galvanized piping is used for water. However, I have this light green piping that I had in storage for 10 to 20 years that I don't know what it was made for. It looks like 1/2" galvanized piping, but it was factory painted light green. I know this is factory paint because the brand "Flecher" was painted on it several times.
Does anybody know for sure what 1/2" light green threaded piping is used for? Thanks.
