Can you still buy R12 Freon for cars?
To be clear, it's against the law to manufacture Freon. But it's still perfectly legal to sell R12 refrigerant. Sellers might require proof of the EPA 609 certification needed to service refrigerant in cars.
What is the direct replacement for R12?
Replacements for R12
The best replacement for R12 is considered to be R-134a. The chemical name of R134a is tetrafluoroethane and it chemical formula is CF3CH2F. It is a hydrofluorocarbon (HFC) and has zero ozone depletion causing potential and very low greenhouse effect.
What Freon did old cars use?
All classic car original air conditioning systems were filled with dichlorodifluoromethane or R-12/CFC-12 Freon. Even newer cars used the standard R-12 until the EPA, under section 609, in an attempt to reduce atmospheric ozone depletion, mandated that manufacturers phase out its use by the end of the 1994 model year.
Is R12 Freon 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 replace R12 with 134a?
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.
Is Freon 12 the same as R12?
Refrigerant R12 or Freon 12 is said to be the most widely used of all the refrigerants being used for different applications. The chemical name of refrigerant R12 is dichlorodifluoromethane and its chemical formula is CCl2F2. ... The wide range of applications of the refrigerant are due to its safe properties.
What do you do prior to introducing recovered refrigerant to a motor vehicle?
Before you begin transferring recycled refrigerant into an empty storage cylinder, in order to remove non- condensable gases, the cylinder must be evacuated to at least 27 in. HG of vacuum. Refillable cylinders must be UL or DOT approved and must be hydrostatically tested and date stamped every five years.
Can you use R12a in a R12 system?
Adding R12a refrigerant to the R12 system:
It's basically the same procedure as adding R12 except you must screw on the R12-to-R12a quick-connect adapter fitting pictured below (included in the kit) to the LOW suction service port first. The adapter fitting has it's own Schrader valve internally, so no gas will escape.
Is there a replacement for R-12 refrigerant?
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.
Can you buy Freon for your car?
If you've confirmed that your vehicle uses R-134 or R-1234yf, or has been converted from R-12, you can purchase a recharge kit which will include the recommended refrigerant, dispensable from a pressurized can of approximately 12 ounces to 22 ounces and in most cases will contain a reusable recharge hose outfitted with ...
Are there different types of Freon for cars?
There are two types of refrigerant or freon – the first one is called R12, while the other one is R134a. ... The R12 refrigerant is still used in some older cars, especially the vehicles that haven't been switched over to a more modern and environmentally safer system. Before 1995 most vehicles used R12 refrigerants.
Why was R12 discontinued?
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.
What oil does R12 use?
Mineral oil is used in the old R12 systems. It has worked well for a long time and is recommended for all R12 applications. R12 takes mineral with it as it travels through the system, meaning it has a high affinity for mineral oil. Mineral oil is not mixed with R134a.
