Default AC compressor O rings ??

Here is a pic of the broken AC manifold that I replaced today on my 72 base 350. It blew COLD air for years. As I install the NEW manifold and hoses .... I can find no evidence of any O rings on this old piece AND none came with the new hose manifold.

LUCY says it should have rubber O rings!

Should it have O rings ????

I truely do not know .... Thanks........

When I took the A/C out of my car I remember it didn't have any O-rings either.

On the back of the compressor , where the manifold bolts into, there are two black thick looking o-rings embeddded into the compressor.

Default Sealing Washers

They are refered to as Sealing Washers and are about a buck a piece. They are a rubber/aluminum configuration. Should be able to get them at most parts stores behind the counter or at the dealer.

The O rings will fit on the compressor side, you will see a circular grove around both the high and low pressure ports, like that :

AutoZone has the new green o-rings that are compatible with R134a.
