L321 (3GS) SUNISO Mineral Refrigeration Oil - 150 SUS, 5 Gallon (ISO 32)

**Image may not represent actual product.** Suniso premium naphthenic based refrigeration and A/C oils have been the AC/R industry standard for over 40 years because of the long trouble-free service records of systems that have used Suniso refrigeration oils . Products L316, L318 and L321 are Copeland Approved. Features: * Low floc point . Low wax content minimizes the potential for wax separation when used in low temperature applications . * Low pour point prevents oil from congealing in refrigerant lines. * Freedom from moisture and other contaminants prevents premature wear and the plugging of lines and oil ports * Controlled viscosity . Maintains high film strength even when diluted with refrigerant, yet remains fluid under extreme low temperature operating conditions. * High dielectric strength allows the oil/refrigerant mixture to serve as an insulator between the motor windings and the body in a compressor. * High chemical stability minimizes the reaction with refrigerants and other materials that are a part of the system. * For use with CFC, HCFC and HC refrigerants, as well as some non-fluorocarbon refrigerants including ammonia.
