Refrigerant Oil

This item includes two types of Refrigerant Oil, one is PAG 100 oil and the other is POE oil.


The purpose of oil in a refrigeration system is to lubricate the compressor that produces cold air. Oil reduces friction on metal parts, reducing wear on the compressor and prolongs the life of the system.


If you recharged your vehicle's air conditioning system with R1234yf Refrigerant and it still isn`t working, or if you have a newly installed A/C compressor, you may need to put the R1234yf Maintenance Product-Refrigerant Oil in it.
