How do you convert R12 to 134a?
How to Convert an R12 to the R134a System
- Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional.
- Open the engine compartment of your vehicle.
- Push the high side retrofit R134a fitting over the old fitting and use a wrench to tighten it.
Can I mix R12 and 134a?
Ultimately, no. If you’re trying to “top off” an R12 system with R134a refrigerant, you can face some hefty fines with the Federal US government and EPA.
What replaces R12 freon?
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 happens if you put R134a in a R12 system?
R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.
What happens if you put R12 in a R134a system?
R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. R12 systems used mineral oil, but unfortunately mineral oil doesn’t dissolve in R134a. So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil.
Do they still make R12 freon?
It became known as R12 or Freon. When used in refrigerator and A/C systems, R12 cooled incredibly well. International manufacturing of new R12 ceased in 1996, but existing R12 can still be reclaimed and purified.
Is it legal to sell R12 refrigerant?
Yes, you can still sell R-12 and other CFC refrigerants. Although these refrigerants can no longer be manufactured, it is perfectly legal to sell to an EPA certified buyer.
Can I add R134a directly to my R12 system?
The easiest way to convert from R12 to R134a refrigerant is by recovering any R12 refrigerant still in the cooling system, adding polyolester oil to the system and recharging the system to around 85 percent of its original capacity with new R134a 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.
