So if I leave the old condenser in there, it'll perform better than it would with R134?
Ok. And that's legal, right? ...ish? I do want to do a pressure test under normal operating pressure, since my test with about 80PSI of air and a spray-down with soapy water probably wasn't the most...
Wait, so if I just did the bare minimum- dryer/accumulator, o-rings and adapters, would I be good for using a hydrocarbon refrigerant? I don't want to have to replace the condenser if I don't have to- finding one and then retrofitting it would be a pain in the neck that I don't want to have to...
Ok. But @brianl703 said that federal law makes it illegal to use that to replace R12...oh wait...is this the part I'm not supposed to mention out loud?
(edit) Also, I'm not sure if it contains oil or not?
Crap, really? I'd hate to have to do that, we already rebuilt the front end...
I found this online for retrofitting an R12 system for R134A:
THE MINIMUM:
Filter drier or accumulator;
High side system “O” rings through to the evaporator inlet;
Add 30-50ml PAO oil to a/c system.
Fit high/low...
Hmm. https://www.intarcon.com/en/refrigerante-r152a/ I think I understood about 5 words in that. Anyway, it looks like you can use 152a to replace 134a, not sure about R12.
