Can I Use Automotive R134a In A Refrigerator

I have found though 134a is 134a the only difference is the stop leak additive they add to the can.

Can i use automotive r134a in a refrigerator.

Don t use premixed oil refrigerant in the domestic refrigerator. 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. R134a operates at higher discharge pressure which can cause compressor seals to leak out. 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. The stuff i purchased was arctic freeze ultra synthetic refrigerant 134a. 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. Can this particular r134a be used or do i need to use only the refrigerant in the larger can.

Some manufacturers have different connections on the cylinder or drum but adapters are available. Both auto and hvac r134 are chemically the same. Never mix refrigerants and never use a refrigerant other than the type specified for your system. I have searched for an hour and still haven t found an answer.

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. R 134a if manufactured to prescribed tolerances is applicable to both systems. 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. 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.

No one there could give me an answer. Here at on time appliance we use the large 30 cans but this is not piratical for the average person who owns a refrigerator. Can i use the can of auto r134a to charge a residential refrigerator that uses r134a. If you own a refrigerator built after 1995 chances are it uses 134a coolant.

In the automotive world the replacement for r12 was tetrafluoroethane a hydrofluorocarbon hfc branded as r134a. My question is this.
