Hello all

I'm looking for part number 04773780. It is a high pressure relief valve that goes on the back of the AC compressor for my 93 B350. If it helps, Supersessions are 04425811 and 04462305.

I am unable to find this part anywhere online and I'd rather not buy an entire compressor if I don't have to. That seems like such a waste.

Does anyone have one for sale, know of one for sale or a replacement part number?

Thanks in advance

 

Who made the compressor? Might call the manufacturer directly, and see if they can help you out.
