AC O Ring Seals

[Haynesie]

Hi All,

I'm in the process of repairing/converting my AC to R134. During the removal of components I'm noticing that there are not O-rings at every connection (probably why the system never worked). Hoping one of you all could provide an overview of where orings are required. I'm assuming the following for starters, but confirmation would be helpful:
1. Rear of compressor (2 or rings)
2. All connections on the accumulator
3. All connections on the Condensor

basically is there any connection where there shouldn't be an oring?

Thanks,
Jason

Short answer = NO.
As for the compressor there's special o'rings for that connection.

If memory serves me correctly, you need the green o-rings.
