Dupont 0131993 High Temperature Grease 8 Lb Nlgi 2

Product Description

The DUPONT 0131993 is a lithium phenylmethyl silicone high temperature grease packaged in an 8 lb can. Rated NLGI Grade 2 with a white color, it is engineered for bearing applications that operate across a wide temperature range, from -40 degrees F up to 400 degrees F maximum, with a dropping point of 432 degrees F. Licensed HVAC technicians, millwrights, and mechanical service professionals use this grease where standard petroleum-based lubricants would break down from heat. The silicone composition maintains structural consistency across extreme temperature swings, making it a reliable choice for high-cycle bearing assemblies in heating, cooling, and industrial equipment.

This grease is intended for use on bearings and bearing assemblies in systems that experience sustained elevated operating temperatures. It is well suited for residential and light commercial HVAC equipment, motors, fans, blower shafts, and similar rotating components where thermal stability is critical. The 8 lb can provides enough volume for fleet service operations or frequent application in shop and field environments. No thinning agents or additives are needed prior to application.

Key Features

• Maximum operating temperature of 400 degrees F for high-heat bearing applications
• Minimum operating temperature of -40 degrees F for cold-start environments
• Dropping point of 432 degrees F indicating high structural stability under heat
• NLGI Grade 2 consistency suitable for most standard grease fittings and nipples
• Lithium phenylmethyl silicone composition resists thermal breakdown and oxidation
• White color allows visual confirmation of grease presence during inspection

Compatibility

Designed for use on bearing grease applications where a high temperature, NLGI 2 lithium silicone grease is specified. Verify OEM grease specifications before applying to sealed or shielded bearings.

Installation Notes

Application should be performed by a qualified technician familiar with bearing lubrication procedures. De-energize and lock out all equipment before servicing bearings or grease fittings. Apply using a standard grease gun fitted to the appropriate grease fitting; do not over-pack bearing cavities, as excess grease can cause heat buildup and premature bearing failure. Dispose of used grease and empty containers in accordance with local regulations.
