Grainger carries refrigeration lubricants to help you keep air conditioning and refrigeration units in top operating condition. Lubricants are the lifeblood of a refrigeration system. They mix with the refrigerant used in the system, so it’s important to use a compatible lubricant. Choose from alkylbenzenes, polyol esters and other refrigerant compressor oils. Check out this selection of refrigeration lubricants at Grainger to find the one that’s right for your refrigeration system.
