Can R12 be replaced with R134a?
R134a is a safer replacement for R12. Another major difference is the type of oil both refrigerators require. R12 is compatible with mineral oil, and most R12 systems use this. R134a uses Polyalkylene Glycol (PAG) oil.
Can you still buy R12 freon?
It’s often said that R12 is no longer available. It’s often said that buying or selling R12 is illegal. That’s not true either. Anyone selling R12 is required to verify that the buyer has an EPA Section 609 certification to work with mobile vehicle air conditioning (MVAC) systems.
Can I still use R12?
It became known as R12 or Freon. When used in refrigerator and A/C systems, R12 cooled incredibly well. And it was safe—neither poisonous to breathe, nor flammable. International manufacturing of new R12 ceased in 1996, but existing R12 can still be reclaimed and purified.
Why is R12 banned?
In conclusion folks R-12 Freon was banned due to the damage that it caused to the Ozone layer. The Chlorine found in CFC refrigerants like R-12 would not break down in the atmosphere when vented or leaked. The Chlorine would then erode the Ozone bit by bit.
Why is R12 illegal?
What is the replacement for R12?
R134a
There are three replacement refrigerant options for R12 systems: R134a, R401a, R401b. R134a is regarded, by manufacturers and adherents to the Montreal Protocols alike, as the best replacement refrigerant.
What do I need to convert from R12 to R134a?
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
What are the advantages of R134a over R12?
Chemistry. R12 is dichlorodifluoromethane (CCl₂F₂) and is classified as a chlorofluorocarbon (CFC).
Can you put R12 in a R134?
Instead you can convert an R12 system to an R134a system with a few parts and some basic tools. Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional. Releasing R12 directly into the environment is dangerous and punishable by law.
Can you mix R12 with R134?
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).
