What does PAG stand for in refrigerant terminology?

PAG stands for Poly Alkylene Glycol in refrigerant terminology. This type of oil is commonly used in refrigeration and air conditioning systems, particularly with certain refrigerants such as those in the HFC (hydrofluorocarbon) family. PAG oils have specific properties that make them well-suited for applications involving high-efficiency compressors and for use with various refrigerants.

They offer superior lubrication, which is essential for maintaining compressor performance and prolonging equipment lifespan. Additionally, PAG oils have excellent thermal stability and can operate effectively over a wide range of temperatures, making them ideal for use in demanding refrigeration applications. This sets them apart from other types of oils that may not perform as effectively in similar conditions.
