Can I Use Automotive R134a In A Refrigerator

Can i use automotive r134a in a refrigerator 2020 09 15t08 21 25 04 00 the concern that the original r12 hoses would leak r134a like a screen door on a submarine appeared to be largely unfounded as the insides of original hoses seemed to naturally become impregnated with a combination of refrigerant and oil that acted as a barrier.

Can i use automotive r134a in a refrigerator. I can usually find the automotive 134 a bit cheaper but legally it requires a licence. Here at on time appliance we use the large 30 cans but this is not piratical for the average person who owns a refrigerator. Note that r134a is also sometimes called freon even labeled as such on the can so it s best to be clear and use the names r12 and r134a. I have found though 134a is 134a the only difference is the stop leak additive they add to the can.

Same thing if you have a car with an r 134a hfc 134 system you can only replace it with r 134a. The result was evident r134a could not cool as well as r12. I have searched for an hour and still haven t found an answer. I didn t have a 30 lb can of r134a but i was able to get a few 12 ounce cans at the auto tool store.

If you own a refrigerator built after 1995 chances are it uses 134a coolant. The molecules of r134a were smaller than r12 so it was feared to leak out of the flare fittings and hoses which were in use by previous r12 systems. Can this particular r134a be used or do i need to use only the refrigerant in the larger can. Depends on how old it is most refrigerators less than 20 years old use 134a same refrigerant used in newer cars the problem would be getting it from the can into the refrigerator as most refrigerators do not have charging ports also they hold very little charge to start with so if it has developed a leak a recharge probably wont last.

The only difference is the thread on the automotive is different they made the change to prevent shop mechanics from using the wrong type of freon. Both auto and hvac r134 are chemically the same. I m thinking yes because r134a is r134a but the cans at autozone have for auto ac only on the front of can. Can i use the can of auto r134a to charge a residential refrigerator that uses r134a.

Don t use premixed oil refrigerant in the domestic refrigerator. R134a operates at higher discharge pressure which can cause compressor seals to leak out. In the automotive world the replacement for r12 was tetrafluoroethane a hydrofluorocarbon hfc branded as r134a. My question is this.

No one there could give me an answer. Some manufacturers have different connections on the cylinder or drum but adapters are available.
