Hello friends, I am starting to repair refrigerators and I need to make a homemade vacuum pump which gave me an old kelvinator refrigerator and the compressor has 5 bone pipes, it has an oil cooler, my query is that it does not have much oil and I want to change it I have in my I deposit oil for R 22 but the moto-compressor is for R 12 my question is if I could replace that oil with the oil for R 22 since I will only use it for vacuum pump which I will put a filter in their respective outputs and tickets and what would you have to do with the two oil cooler pipes, I leave them like this or I pay them by plugging them in the tips already thank you very much for the contribution

With a compressor to be empty, I do not recommend it, it is better to get a pump.

Hi, you can use that oil and plug the tubes Only if a vacuum pump does not have the necessary effectiveness, it will leave moisture in the system when there is one and your work will not have the effectiveness you expect.
