Dupont 0131981 Low Temp Grease 40 Lb Nlgi 2 Lithium Silicone

Product Description

The DUPONT 0131981 is a low temperature, NLGI Grade 2 bearing grease formulated with a lithium and phenylmethyl silicone composition. Packaged in a 40 lb pail, this grease is engineered for extended service in applications where cold-weather performance is critical. It carries a minimum operating temperature of -100 degrees F and a maximum operating temperature of 400 degrees F, giving it a wide thermal range suitable for demanding mechanical environments. The pink color aids in visual identification during maintenance checks. HVAC technicians, mechanical contractors, and industrial service professionals working with bearing-equipped equipment will find this formulation appropriate for regular preventive maintenance applications.

This grease is suited for bearing lubrication in both residential and light commercial HVAC systems, as well as broader industrial mechanical applications where low-temperature performance is a service requirement. Its medium consistency rating and lithium-based composition make it a practical choice for technicians servicing equipment in cold storage facilities, outdoor installations, or other low-ambient environments where standard greases may harden and lose effectiveness. The 40 lb pail size supports shop or fleet service operations.

Key Features

• NLGI Grade 2 medium consistency suitable for standard bearing lubrication
• Wide operating range from -100 degrees F to 400 degrees F
• Lithium and phenylmethyl silicone composition for low-temperature stability
• Dropping point of 439 degrees F, reducing risk of grease migration under heat
• Pink color for easy visual identification in multi-product service environments
• 40 lb pail format suited for high-volume service or shop use

Compatibility

Designed for bearing lubrication applications across HVAC, mechanical, and industrial service contexts where low-temperature grease performance is required.

Installation Notes

This grease is applied by qualified mechanical technicians using a grease gun or direct packing method appropriate to the bearing type. Always de-energize and lock out equipment before servicing bearings. Avoid mixing with greases of different base compositions, as incompatible blending can degrade consistency and performance. Follow equipment manufacturer specifications for re-greasing intervals and fill quantities.
