What is PAG lubricant used for?

PAG (Polyalkylene Glycol) lubricant is primarily used in applications requiring high-performance lubrication, particularly in refrigeration and air conditioning systems. It is known for its Excellent thermal stability, low volatility, and ability to mix with water, making it suitable for use with various refrigerants. Additionally, PAG lubricants provide superior wear protection and have a high viscosity index, enhancing their performance in extreme temperature conditions.
