FAQ:
Q: Can you put R12 in a R134 system?
A: Recharging an automobile air-conditioning system is rather simple, however, R12 refrigerant is difficult and expensive–you must be a licensed professional to buy it. Instead you can convert an R12 system to an R134a system with a few parts and some basic tools.
Q: Can you mix R12 with R134?
A: You cannot mix R-12 with R-134a, they are not compatible (and neither are the compressor oils used with them). If you have a R-12 system, you either need to use R-12 (make sure you fix the leak first, it’s currently selling for about $60/pound), or “convert” the system to R-134a (including having it flushed and evacuated).
Q: What do I need to convert from R12 to R134a?
A: What you need to convert R12 to R134a using the factory method AC flush kit Complete HNBR O-ring kit for your vehicle R134a retrofit kit with R-134a port adapters, oi, port caps and retrofit label R134a pressure switches R134a orifice tube New barrier style hoses for pre-1990’s vehicle New R134a accumulator/dryer
Q: Is R12 and R134a compatible?
A: The R12a cans use the same taps as the R134a cans and the supplied hose has R134a compatible fittings on both ends, so R12a can be used to recharge R134a systems too. All in all, I’m very happy with the results and see no reason why they won’t last. Well worth the money if your A/C system is still in good shape.
