never mix these freons together---- very dangerous
R-134A
No, a 12 oz can of R-134A refrigerant is equivalent to 0.75 pounds.
No
R-12 is very harmful to our enviroment.
Probably uses R-12 refrigerant but if you are having a problem with your ac you should convert to the new R-134a refrigerant . Look for a decal under the hood or on the compressor to make sure. The two refrigerants do not mix.
The example of CFC is R-12. It is being used as a refrigerant.
R-134a is the only refrigerant approved by the automotive industry. It requires conversion to be used in an R-12 system.
If it is the original refrigerant, it's R-12 (which is not longer available). If it was converted, it has R-134A. You can tell by the type of service port (the fitting for replacing the refrigerant). The service port for R-12 has threads, R 134A does not.
No its not. 409a is compatible with r-12 but not 134a.
The short answer is yes. However, the A/C system must be retrofitted (changed from R-12 to R-134a). Many people believe that you can simply add R-134a in place of R-12 without retrofitting. However, this is not recommended because you can do damage to the A/C system. Remember that you are mixing two different refrigerants and refrigerant oils.
R-134a ( I believe since the 1994 Ford Explorer model year )
