No, the two cannot be blended.
No
Is r-22 Freon compatible with r-134a freon?
AnswerNO! The problem is that the lubricating oils are not compatible, and the mixture will clog the system.
No , they operate at different pressures and are not compatible.
The newer Freon (r134) does not mix with the old Freon. The system needs to be flushed, special oil added so that r134 will be compatible with the system gaskets, then a vacuum pulled. Then the Freon can be added.
r134
R134 .... IS freon.
You do not want to buy Freon as it is very, very, expensive. Have the leak repaired, the system purged of all Freon R12 and the oil. Have it converted over to R134 refrigerant. You cannot just add R134 as the oil used in R12 is not compatible with R134. You will be money ahead by converting it.
NO ! and Why?
Wal-Mart do not have r22 freon, this is a false ad.
R134
