Liqui Moly PAG Air Conditioning System Oil 46 is a fully synthetic, polyalkylene glycol (PAG)-based oil which is used for the lubrication, sealing and cooling of refrigerant compressors or refrigerant circuits in passenger or commercial vehicles air conditioning systems. Liqui Moly PAG Air Conditioning System Oil 46 has been formulated so that it can be mixed with Type R 134a refrigerants and is therefore outstandingly suitable for this purpose. Liqui Moly PAG Air Conditioning System Oil 46 is hygroscopic and absorbs moisture from the surrounding air. The oil is therefore filled under nitrogen. This product complies with the requirements of standard refrigerant compressors and refrigeration system manufacturers.
