Can I Use Automotive R134A In A Refrigerator?

I assume you mean a household fridge so obviously you have a question Can I Use Automotive R134A In A Refrigerator? It may be utilized; however, the scale is different; there are two typical “gases” in the US that are used for medium temperature applications (depending on where you are; I’ve heard of other refrigerants in different places). Mp -39 and 134a you can utilize 134-a, but the question is, what is currently in there?

What is the explanation for this? The oils differ depending on the refrigerant; polyester oil is recommended for 134-A Refrigerator. If it’s an old r-12 system, the mineral oil will need to be changed, which is a difficult task in a sealed system, let alone without experience; small systems like that have no provisions for oil extraction and replacement, so you’ll have to cut out the compressor, drain it, and reinstall with proper oil.

After that, if there is still a label, look up what oil is comparable to that refrigerant on the internet. I’ve heard and seen several unusual things done in the field, such as mixing gases, which they claim is a big no-no but worked great, using the wrong oil, and mismatched parts. If you can’t decide whether to fix it or buy a new fridge, go ahead and test it.

The label (if there is one) will tell you how much by weight is in the system; the normal fridge takes roughly 8–12 oz, so the whole (usually 14oz) can won’t fit. You’ll need to obtain a piercing valve, read the instructions, and install it (either on the larger of the two lines on the compressor, or on the small little line that is crimped off at the end). In most cases, you’ll need to use a vacuum pump to evacuate the system, but if it’s not completely empty, you might be able to avoid this step.

Automotive Refrigerants

In car air conditioners, two types of refrigerants are employed. The first is known as R12, while the second is known as R134a. They may appear to be identical part numbers, yet there are significant variances between them. To begin with, R12 is the one found on older vehicles. It’s known by the brand name Freon, and it got a bad rap once scientists discovered that it was contributing to the ozone layer’s depletion.

Some older cars, particularly those that have not been switched to a more modern and ecologically friendly system, still employ R12. Before 1995, R12 refrigerants were utilized. As a result, if your vehicle had air conditioning, this was a standard feature. Some people have upgraded their air conditioning systems since then, and cars manufactured after 1995 were all equipped with R134A Freon, a refrigerant that is not thought to be harmful to the environment.


So concluding the above information about Can I Use Automotive R134A In A Refrigerator? R-134A can be used in both systems if it is made to strict standards. Although some manufacturers’ cylinders or drums have various connections, adapters are available. In a household refrigerator, do not use premixed oil or refrigerant. If your refrigerator requires refrigerant, moisture has most likely entered the system due to a leak. Cleaning up was a big nuisance, and it was also quite costly.

Frequently Asked Question

Can I use R134a from a car in a freezer?

No, it can’t be used in freezers that need a lower-temperature refrigerant. In automobile systems, 134a is less efficient than the original Freon-12. Refrigeration refrigerants from automobiles and refrigerators should never be mixed.

Is R134A Freon used in refrigerators the same as it is in automobiles?

R-134a, an HFC, is often used as a refrigerant in refrigerators made from 1995 to the present. R-134a is a refrigerant that is used in both refrigerators and autos, and it can be purchased by adults at most auto parts stores. The compressor will be locked up if the no compatible refrigerants R-12 and R134a are used together.

In a refrigerator, what pressure does 134a run at?

In a 134a refrigerant system, a normal pressure gauge is used. The coil operates at a pressure of 57 pounds per square inch gauge for the highest temperature. As a result, R134a’s standard pressure gauge spans from 22 to 57 pounds per square inch.

Is it true that all R134a refrigerants are the same?

Unless there is an addition in R134A that is listed on the label, there is no difference between brands. Some feature a leak sealant, which you should never, ever use. The only significant distinction is in price, Suva R134A Refrigerants by DuPont.

Is 134A charged as a vapor or a liquid?

Because gas is always on top of the can, holding it upright will charge the gas, which will then turn into liquid.
