The advantage of ester oil is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant. This means that this compound is made up of carbon, chlorine, and fluorine. R134a Expansion valve different from R12? - Automotive Air Conditioning We suggest dumping the old refrigerant oil in a clean container and inspect the oil for sludge or waxing (old oil that has gelled) and contamination (metal particles). Certainly no one selling cans of R12 on Craigslist is asking for your EPA 609 card. Second, as youll see below, if you have to perform work on an A/C system that has refrigerant in it, it is illegal to vent the refrigerant (to let it escape into the atmosphere); it must be captured and recovered. R12 is recognized as a very stable compound, and it wont break down under even the most stringent conditions, but if it comes in contact with flames or electrical heating elements, it breaks down into toxic components. A comparison between R12 vs. R134a temperature will show that R12 has a higher temperature than R134a. What Happens If You Put R134a in an R12 System? - techtown These are cars with poor A/C reputations, which is precisely why I continue to use R12 in them. This product is non-toxic, non-flammable, and not explosive, so its extremely safe to use for domestic refrigeration. Its possible to convert from R12 to R134a without replacing the systems components, so when R134a was brought out, it seems to be a good match to many automotive air conditioning issues. The conversion to more modern refrigerants will require a replacement of the system, which will cause issues in terms of originality when showing this type of vehicle. Here are a few of the more common questions. R12 connectors were of the screw type, while R134a has push-on connectors similar to air tools. Failure to abide by the EPA regulations can result in expensive fines for either you or your service technician. Another way to check is to look at the air conditioning connectors. Its been likened to trying to convert a petrol engine to run on diesel. Sign up for the latest automotive news and videosin short, everything for people who love cars. Therefore, the R12 refrigerant is illegal, and emitting it is illegal.
