Product Info
Fully synthetic oil which is used for lubrication, sealing and cooling of refrigerant compressors or refrigerant circuits in passenger or commercial vehicles’ air conditioning systems. Miscible with type R134a fluids. Complies with the requirements of standard refrigerant compressors and refrigeration system manufacturers.
Wet the seals with a brush during assembly. To top up or replace the refrigerant oil use a special filling cylinder and an air conditioning system filling device. Always reseal the package after use to prevent the oil from absorbing moisture from the air.
Automotive air conditioning compressors require specific types of lubricants. Most 1996 and newer A/C systems use the R134a refrigerant and require some type of PAG (polyalkylene glycol) oil for the compressor. If the wrong type of compressor oil or the wrong viscosity compressor oil is used, it may damage the compressor. In fact, the main reason for a newly installed A/C compressor to fail is using the wrong type of compressor oil.
CAUTION:
PAG oils should NEVER be used in hybrid vehicles because they are electrically conductive. POE (polyol ester) oils are usually specified for hybrid cars that have electrically driven A/C compressors because they are non-conductive. Using the wrong oil may allow current to short circuit back through the A/C compressor, creating a shock hazard.
Mineral oils should only be used in older R-12 A/C compressors because R-12 will not mix with the R134a refrigerant.
”Universal” A/C compressor oils are often PAO-based and do not have the same viscosity as the PAG oils recommended for a specific type of compressor. This can lead to poor lubrication and premature compressor failure.
PAO (Polyalphaolefin) oil can sometimes be used as a substitute for certain PAG oils if the compressor manufacturer approves it.
Newer vehicles with R-1234yf A/C systems require a special 1234yf compressor oil specified by the vehicle manufacturer. General Motors recommends GM lubricants only (PAG-PSD1 #19260643 for 2013/14 Cadillac XTS, and PAG-ND12 #19299051 for 2013 Cadillac ATS). Universal compressor oils should NOT be used in R-1234yf applications.
