The simple answer is that an R12 system wasn't designed for R22. There are different pressures reached, there are different compressor oils used, and R22 may not even be compatible with a compressor designed for R12. Changing an R12 system to R22 could be done, but it would require extensive conversion, and would still be undesirable - R22 is being phased out, largely because it's a carcinogen and because of the harsh environmental effects.

Can R22 be used in a R12 system?
No, R22 is for refrigerators and home AC. It runs at a different pressure and you can't use one for the other.
Can you interchange R22 to R12?
There are kits to do this, but I don't recommend it.
How do you convert R12 freon to R22 freon?
You cAnt sorry
Is R12 Compatible with R22?
No it's not. R22 is designed for use in home HVAC systems where as R12 is intended for automotive systems. Using R22 in an automobile will cause swelling of seals and hoses, possible compressor failure due to different running pressures.
Is r12 r22 compatible?

Can you mix r22 and r12 freon?
It is not recommended.
What other refrigerant besides R12 can be used on a 1988 Toyota Camry?
No. R12 systems are designed for R12. The lubricating oil for 134a is synthetic and will attack the o-rings in a R12 system. I think the operating pressures are also different.Samething is now happening to residential ACs. R22 is out and 410 is in.They are not compatible.SOL
What forms when R12 and R22 gas decompose at high temperature?
phosphoric acid
Can the same lubricant oil be used for r12 r22 r134a co2 refrigerant in refrigerator?
No
Which refrigerant has the lowest condensing temperature R12 or R22 or R500 or R410a?
R-12..........
You have a R22 system wit the compressor shot can you use a R12 compressor?
No. The entire cooling system is designed to use a specific refrigerant. To change any one component would throw every thing off.
What kind of Freon do you use in a 1994 Toyota Corolla?
my 1993 Toyota corolla was r12 but i converted it to a r134a easily all you have to do is change the fittings and flush out the system i don't even know if you can get r12 anymore all shops would suggest converting your system. You need to have the system evacuated of the R22 at a licensed A/C repair facility that can disposed of the R22 correctly. Best bet is to have the a/c experts do the conversion. It is more than just changing fittings because the dryer needs to be replaced with one compatible to the new R134. If this is not done, the A/C system can possibly explode from the difference in pressures between the two different types of refrigerant. And the A/C will not work correctly.
