描述
Krytox GPL 203 is a high performance PFPE (Perfluoropolyether) grease, genuinely manufactured by Chemours and imported as original product. As an authorized distributor and trader, we supply genuine material with full traceability and direct access to official Chemours technical documentation.
This white, buttery, NLGI Grade 2 grease is formulated with a PTFE thickener and contains no additives. It is part of the Krytox GPL 200–207 series of general purpose greases, which share the same properties as the GPL 100–107 oils they are made from, but in grease form. GPL 203 is the higher-viscosity grade (30 cSt @ 40°C) in the series, offering excellent high-temperature stability while maintaining good low-temperature fluidity.
Krytox GPL 203 is a severe-service grease for bearings, valves, seals and other applications where heat resistance, low volatility, chemical resistance and a wide temperature range are critical. It is chemically inert, non-flammable, and safe for oxygen service. The grease is compatible with all types of seals, including O-rings, and can be used safely when components come in contact with virtually all chemicals including alcohols, ammonia, solvents, steam, acids, and bases. It is also NSF H-1 certified for incidental food contact.
With regular stock availability, we support both trial orders and large‑volume bulk shipments for automotive, industrial, and demanding applications.

Material Advantages of Krytox GPL 203
What makes Krytox GPL 203 the preferred choice for high-performance and demanding lubrication applications? Below are its core practical advantages:
Extreme Temperature Performance
With an estimated useful temperature range from -60°C to 154°C (-76°F to 310°F), Krytox GPL 203 performs reliably in both cryogenic and high-temperature environments. Its higher-viscosity PFPE base oil provides excellent high-temperature stability while maintaining good low-temperature fluidity.
Exceptional Longevity
Under D-3336 test conditions at 177°C (350°F) and 10,000 rpm, the majority of competing hydrocarbon lubricants fail in less than 1,000 hours. However, the general purpose line of Krytox lubricants has been shown to last over 5,000 hours without failure, even at an increased temperature of 200°C (392°F). This extreme longevity reduces maintenance costs and downtime.
Chemical Inertness & Non-Flammability
Krytox GPL 203 is chemically inert and will not react with virtually all chemicals. It is non-flammable and safe for use in oxygen service (LOX and GOX). The absence of hydrogen in the PFPE molecular structure greatly increases stability and renders the lubricants non-flammable with no flashpoint.
NSF H-1 Certified for Incidental Food Contact
Krytox GPL 203 is NSF H-1 certified for incidental food contact, making it suitable for applications in food processing and packaging where incidental contact with food products may occur.
Compatibility with Seals & Elastomers
Krytox GPL 203 is compatible with all types of seals and does not damage plastics or elastomers, nor cause corrosion to metals.
Silicone-Free & Environmentally Inert
Krytox GPL 203 does not contain silicone, chlorine, or volatile organic compounds (VOC). It is not hazardous to the atmosphere or ozone layer and is biologically and environmentally inert.
Cost-Effective
Due to their inert nature, Krytox lubricants provide a much longer usable life as compared to typical hydrocarbon oils and greases. This translates to savings over time, both by lowering the amount of lubricant purchased and any downtime incurred during re-lubrication.

Surface Preparation: When using Krytox as a lubricant, thoroughly remove all existing grease or rust preventive oils from components.
Compatibility: Krytox greases are compatible with other PFPE/PTFE lubricants, but should not be mixed with other common types of lubricants.
Additive-Free: GPL 203 contains no additives. For applications requiring extreme pressure (EP) or anti-wear performance, consider Krytox GPL 215 (with MoS₂) or other GPL grades with additives.
Storage: Store in original, sealed containers in a cool, dry place away from direct sunlight.
Solvent Cleaning: Krytox GPL 203 is insoluble in conventional solvents. Special solvents are required for diluting, cleaning and removing Krytox products.
