Hi, replace my ac compressor and went to ACE hardware to pick up 2 rubber washers black in color. The original is green, will it matter or must install the same color green washers. Thanks.

The composition of the rubber O rings are different......the black is for the old R-12 systems.......the green is for the R-134a systems. Yes, IMHO.......you should use the correct ones.

USUALLY.......Nitrile and HNBR are the two common O rings found on an AC system. Nitrile (black) for R-12 and HNBR (green) for 134a.

Though, I have also heard that just the color alone doesn't tell you the whole story........so, double check what you got.


Aloha, Mark
