Dupont 0131991 High Temp Grease 14.1 Oz Nlgi 2 Cartridge

Product Description

The DUPONT 0131991 is a high temperature lithium phenylmethyl silicone grease packaged in a 14.1 oz cartridge. Formulated to an NLGI Grade 2 consistency, it delivers reliable lubrication across a wide service range of -40 degrees F to 400 degrees F, with a dropping point of 432 degrees F. The white-colored grease is designed for bearing applications where thermal stability and resistance to breakdown under sustained heat are required. HVAC technicians, refrigeration mechanics, and industrial maintenance personnel use this grease on motor and blower bearings in systems that see high operating temperatures or wide temperature swings.

This grease is suited for bearing lubrication in residential and commercial HVAC equipment, including motor bearings on air handlers, furnace blower motors, and similar rotating components. The cartridge format is compatible with standard grease guns, making it practical for field service and routine preventive maintenance on equipment where heat exposure can degrade standard petroleum-based greases. Its lithium phenylmethyl silicone composition resists oxidation and thermal degradation better than conventional mineral-oil greases at elevated temperatures.

Key Features

• Operating range of -40 degrees F to 400 degrees F for reliable performance across extreme temperatures
• Dropping point of 432 degrees F provides a wide safety margin at sustained high heat
• NLGI Grade 2 consistency for standard grease-gun application
• Lithium phenylmethyl silicone composition resists thermal breakdown and oxidation
• 14.1 oz cartridge fits standard caulk-style grease guns used in field service
• White color for visual confirmation of application coverage

Compatibility

Designed for bearing lubrication applications where a high-temperature NLGI 2 grease is specified. Suitable for use on bearings in HVAC motors, blowers, and similar rotating equipment that require grease rated for service up to 400 degrees F.

Installation Notes

Application should be performed by a qualified technician following equipment manufacturer lubrication intervals. Power down and lock out the equipment before accessing motor or bearing grease fittings. Load the 14.1 oz cartridge into a compatible grease gun before use. Avoid overpacking bearings, as excess grease can cause heat buildup and premature bearing failure.
