Help! RV2 compressor blew new shaft seal

67Dart273 said
I'm told R12 rubber components can be "iffy" with 134. So not knowing? what they used? Might be wear on the shaft, this a rebuilt compressor?

I would not think that overcharge would affect the seal.

It is very probable that careless or improper installation could have condemned that seal

I had a member here be build my hoses with barrier hoses for 134and my compressor was rebuilt. I will have them very carefully check the shaft. I understand that you can run the seal if you handle it. You must coat in oil prior to installation.

Thanks. Gary
