Dupont 0131849 High Temp Fluorosilicone Grease 19.4 Oz

Product Description

The DUPONT 0131849 is a high temperature fluorosilicone grease fortified with polytetrafluoroethylene (PTFE), packaged in a 19.4 oz cartridge. It meets NLGI Grade 2 consistency and carries a white color for easy visual identification. The formulation is rated for continuous service from -40 degrees C to 230 degrees C, with a dropping point of 280 degrees C, making it suitable for demanding thermal environments. This grease is applied by HVAC technicians, industrial mechanics, and equipment service professionals working on bearing-intensive assemblies where conventional petroleum-based greases break down under heat or chemical exposure.

The 0131849 is designed primarily for bearing lubrication in high temperature service conditions. Its fluorosilicone base provides strong resistance to heat, oxidation, and chemical attack, while the PTFE additive reduces friction and wear on metal contact surfaces. Typical installation scenarios include electric motor bearings, blower shaft bearings in HVAC equipment, and other rotating components exposed to elevated operating temperatures. The cartridge format is compatible with standard grease guns used in field and shop service environments.

Key Features

• NLGI Grade 2 consistency for reliable pumpability and retention in bearing cavities
• Operating range of -40 degrees C to 230 degrees C suits extreme thermal cycling applications
• Dropping point of 280 degrees C reduces risk of grease migration under high heat
• Fluorosilicone base resists oxidation and chemical degradation
• PTFE additive lowers friction and extends bearing service life
• 19.4 oz cartridge format works with standard grease gun equipment

Compatibility

Designed for use as a bearing grease in high temperature applications where fluorosilicone-based lubrication is specified. Refer to equipment manufacturer documentation to confirm suitability for specific bearing types and materials before use.

Installation Notes

Application is performed by qualified mechanics or service technicians using a standard grease gun fitted to the appropriate bearing fitting. De-energize and lock out equipment before servicing any bearing or rotating component. Avoid overpacking bearing housings, as excess grease can cause heat buildup and premature bearing failure. Confirm compatibility with bearing seals and adjacent elastomers prior to application, as silicone-based compounds may affect certain seal materials.
