Factory AC compressor hose connection

[texasmike]

I had the R4 compressor replaced with a new ACDelco unit and it is slowly leaking Freon at the double hose connector. It is held in place with a single bolt and has two O-rings. It looks like one is red and the other is green. Is that correct or should they both be the same color and type?

Both should be green and coat them with compressor oil.

Some of those compressors take a different thickness seal between the pressure and suction sides.

You may need the crackhead AC Delco sealing washer chart, if you have a newer hose set or a compressor without the relief for the big o-rings (which were universal for decades).

I've got a new hose set and a very late Dephi service compressor. I had a pic where you could see the washer colors, but I can't seem to find it. I want to say I needed a yellow and green. Getting the manifold flat against the compressor is the object of this exercise.
