Dupont 0131850 High Temp Fluorosilicone Ptfe Grease 10 Lb

Product Description

The DUPONT 0131850 is a high-temperature fluorosilicone grease with polytetrafluoroethylene (PTFE) fortification, formulated for demanding lubrication applications where standard greases fail. Classified NLGI Grade 2, this white grease maintains structural integrity from -40 degrees F to 446 degrees F (-40 degrees C to 230 degrees C) and carries a dropping point of 536 degrees F (280 degrees C). The 10 lb pail format suits shop-stocked service operations, fleet maintenance facilities, and industrial service teams who need reliable volume supply for bearing and component lubrication under elevated heat conditions.

This grease is designed for bearing lubrication in environments where high temperatures, chemical exposure, or wide thermal cycling would degrade conventional petroleum-based or standard silicone greases. The fluorosilicone base provides resistance to fuels, oils, and solvents, while the PTFE additive reduces friction and improves load-carrying performance. Typical applications include HVAC blower shaft bearings, pump bearings, valve stems, and mechanical assemblies subject to sustained heat. It is commonly applied by HVAC technicians, industrial maintenance mechanics, and refrigeration service professionals during scheduled maintenance or component replacement work.

Key Features

• NLGI Grade 2 consistency for general-purpose bearing lubrication
• Operating range of -40 degrees C to 230 degrees C for wide thermal coverage
• Dropping point of 280 degrees C, indicating excellent high-heat stability
• Fluorosilicone base resists fuels, solvents, and chemical degradation
• PTFE additive reduces friction and improves wear protection under load
• White color aids visual confirmation of grease application coverage

Compatibility

Designed for bearing lubrication in high-temperature mechanical assemblies where fluorosilicone chemistry is specified. Verify compatibility with elastomers and seals before applying to sealed-bearing assemblies, as fluorosilicone compounds may not be compatible with all seal materials.

Installation Notes

Applied by qualified HVAC technicians, refrigeration mechanics, and industrial maintenance personnel. Always de-energize and lock out equipment before servicing bearings or lubricated components. Apply grease in controlled quantities per the equipment manufacturer's specification to avoid over-packing, which can cause bearing overheating. Store the pail sealed and away from direct heat or ignition sources when not in use.
