Dupont 0131977 Low Temperature Grease 8 Lb Nlgi 2

Product Description

The DUPONT 0131977 is a low temperature lithium phenylmethyl silicone grease formulated for bearing applications that demand reliable performance across a wide thermal range. Rated NLGI Grade 2 with a medium consistency, it handles temperatures from -100 degrees F to 400 degrees F, making it suitable for environments where standard greases would harden, separate, or break down. The pink-colored compound carries a dropping point of 439 degrees F, indicating strong resistance to liquefaction under heat. It ships in an 8-pound can. This grease is applied by HVAC technicians, millwrights, and mechanical service professionals working on equipment exposed to extreme cold or elevated heat cycles.

This grease is designed for bearing lubrication in low-temperature service environments, including refrigeration equipment bearings, outdoor mechanical assemblies subject to cold climates, and industrial rotating components with wide operating temperature swings. Its silicone-based composition provides stable viscosity at both temperature extremes, keeping bearing surfaces protected where petroleum-based greases typically fail. Typical install scenarios include fan motor bearings, blower shaft assemblies, and other rotating components in HVAC and refrigeration systems.

Key Features

• Operating range of -100 degrees F to 400 degrees F suits extreme cold and heat applications
• Dropping point of 439 degrees F resists grease liquefaction under sustained high heat
• NLGI Grade 2 medium consistency for standard bearing packing and lubrication fitting compatibility
• Lithium phenylmethyl silicone composition delivers stable viscosity across the full temperature range
• Pink color aids identification and visual inspection of lubrication coverage
• Packaged in an 8-pound can for bench or field service use

Compatibility

Designed for bearing grease applications per UNSPSC code 15121902; suitable for use on bearings where a low-temperature NLGI 2 silicone-based grease is specified by the equipment manufacturer.

Installation Notes

Applied by qualified HVAC technicians, refrigeration mechanics, or industrial maintenance professionals. Shut down and de-energize all rotating equipment before repacking or regreasing bearings. Use a calibrated grease gun or clean applicator to avoid contamination of the compound. Follow equipment manufacturer specifications for grease quantity and relubrication intervals.
