Time to replace my compressor

[marshallsmith27]

I am making a new post because this is slightly different than the posts that came up when I searched.

My compressor is dying and getting very hot. Its making a weird noise. I bought a new compressor, accumulator and pressure switch that goes on the accumulator and orifice tube today but as soon as I left the parts store I realized I need more.

The kit that had the accumulator and orifice tube also has o rings but theyre green and I read online that I need black o rings.

Where can I get a kit for black o rings?

my ac was working up until a week ago. it technically still works but is loud and not as cool now. around 60º. I am putting r12 back in the system so I dont need to replace the condenser and hoses and all that I assume?

Anything else I need other than mineral oil? I have a 3 pound tank of r12

Since the kit they sold me was for r134a is the orifice tube good for r12?

Let us know how your project goes. I have had ZERO luck getting ANY of the after-market compressors from O'Reillys to last more than a year. They ALL seem to start leaking at the case halves where the two sections of the compressor body are pressed together. I always use dye when charging my system, and every year I'm replacing my "lifetime" warranty A/C compressor because I'll be changing the engine oil and see green dye dripping out of the compressor body... Every.... Single.... Year...... If you get a compressor that does not leak, please post what brand, and where you bought it, and let us know if it is still leak free in a year.

I’m sure someone can correct me but I think harbor freight has a mixed o ring set.you could try to match one at least close to the one you need.

You might check with " Four Seasons " AC people, but all AC orings are green now, to be compatible with refrigerant, but I haven't serviced an R12 system in over 20 years.

I installed a GPD scroll type compressor in my 94 in 21. Still blowing very cold. But it's not R12. Rockauto purchase.

Where did you read that? I've been using green ones for years.

I've heard decent things about Sanden compressors, but that is literally hearsay from me until I get around to replacing mine that's slowly leaking in the same place you described.

I have read that all over the internet.
