Compresso A/C PAG oils are high-quality synthetic oils based on PAG polar polyglycols. They are intended for use in the air conditioning system of motor vehicles. They are characterized by excellent thermal, chemical and oxidation resistance, as well as a very high viscosity index and low pour point, which provide the oils with very good rheological (viscosity) properties at negative temperatures. Compresso A/C PAG oils are compatible with the following refrigerants: R134a, R1234yf, R717, R723.
