is r12 still available

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.

Can R134a replace 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.

What is the best replacement for R12 refrigerant?

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.

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.

Can I use R22 instead of R12?

R12 and R22 are both now banned by the EPA in the United States. Other more environmentally friendly alternatives exist, but even those cannot be changed in air conditioners or other refrigeration units with R12 without a thorough cleaning of the unit.

Is R12 Freon illegal?

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 mix R12 and 134a?

Mixing R12 and R-134a refrigerants is illegal, and even if you previously bleed out the R12, the system has to be adjusted to use R-134a, or it will cause leaks, copper corrosion, and lack the lubrication required for optimal operation.

Is R12 colder than R134a?

R12 can blow 6 to 7 degrees cooler than R134a and is 15% more efficient. R134a systems require larger condensers and higher operating pressures than R12 systems because R134a doesn’t have as high of a heat transfer rate as R12 (which has a heavier molecular size than R134a).

Why did R134a replace R12?

R12 contains CFCs like hairspray once did, that is potentially damaging to the ozone layer. It was banned because of this potential environmental risk and replaced by 134a because 134a, using synthetic oil over mineral oil, does not have as much of a negative environmental impact that R12 does.

Is R12 flammable?

Both R12 and R134a are non-flammable. No refrigerants currently used in automotive applications are rated A2.

Can you mix Freon with R22?

Mixing R22 with R407C or any other refrigerant. According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.

What is R417A?

R417A, also known as ISCEON ® MO59, is an HFC retrofit refrigerant for R22 in direct expansion stationary air conditioning (AC) and medium temperature commercial refrigeration systems.
