Can you still buy R12 refrigerant?
Can you still buy R12 refrigerant?
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.
What is the best replacement for R12 refrigerant?
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.
Is R12 refrigerant illegal?
R-12 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. R-12 has many applications in refrigeration and air conditioning including large to mediums size chillers, automotive air conditioning, and as an aerosol propellant.
Can you use 134a in place of R12?
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.
Is R12 colder than R134a?
R12 can blow 6 to 7 degrees cooler than R134a and is 15% more efficient. As a result, a perfectly functioning R12 system will blow colder and reduce temperatures faster than a system that was converted to R134a.
Can I replace R12 with r600?
R600a is a good replacement for R12 With regard to R600a, it has a lower molecular weight, 58.1 kg/kmol in comparison to R134a, 102 kg/kmol, which results in a lower charge for Isobutane. R600a also has lower operating pressures than R134a, improving reliability and extending life of the compressor.
Can you convert R12 to R134a?
Before 1995 most vehicles came with R12 refrigerant in the air-conditioning system. If your air conditioning is no longer cooling as well as it once did, then chances are you need to recharge the refrigerant in the system. Instead you can convert an R12 system to an R134a system with a few parts and some basic tools.
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.
How do I switch from R-12 to R134a?
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.
What component Cannot be flushed?
Accumulators, receiver driers, lines and hoses with filters and mufflers CANNOT be flushed and must be replaced.
What happens if you put R12 in a R134a system?
Is there a place to buy R12 refrigerant?
