Understanding Polyalkylene Glycols (PAG)

Understanding Polyalkylene Glycols (PAG) PAG lubricants are a family of synthetic base lubricants used across refrigeration, heat pump, and hydrocarbon gas compression applications. Unlike mineral lubricants, PAGs come in several distinct chemistries — each with different solubility, miscibility, and dilution behaviour with both refrigerants and process gases. Selecting the right type depends on the gas […]
