Dupont 0131983 High Temp Grease 14.1 Oz Nlgi 2 Cartridge

Product Description

The DUPONT 0131983 is a high-temperature bearing grease formulated with a lithium phenylmethyl silicone base and rated NLGI Grade 2. Packaged in a 14.1 oz cartridge, it is designed for standard grease gun application in the field or shop. The grease handles a wide service temperature range, from 0 degrees F at the low end up to 550 degrees F maximum, with a dropping point of 572 degrees F. Its black color and semi-solid NLGI 2 consistency make it easy to identify and work with. HVAC technicians, refrigeration mechanics, and industrial maintenance professionals rely on this grease to protect bearings operating under elevated heat conditions.

This grease is suited for residential and commercial bearing applications where high operating temperatures or thermal cycling would break down conventional mineral-oil-based greases. Common install scenarios include electric motor bearings, blower wheel shaft bearings, and other rotating components inside HVAC equipment. The cartridge format fits standard 14 oz grease guns, making it a practical choice for service technicians performing preventive maintenance or bearing replacements on-site.

Installation Notes

Applied by licensed HVAC technicians, refrigeration mechanics, or industrial maintenance trades using a standard grease gun. Power down and de-energize all equipment before servicing any bearing. Avoid over-greasing, which can cause bearing failure — apply only the quantity specified by the equipment manufacturer. Dispose of used grease and empty cartridges in accordance with local regulations.
