描述
Krytox GPL 202 is a general purpose 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 202 is the medium-viscosity grade in the series, offering a balance of low-temperature fluidity and high-temperature stability.
Krytox GPL 202 offers outstanding chemical, thermal and mechanical properties. 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.
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 202
What makes Krytox GPL 202 the preferred choice for general-purpose and demanding lubrication applications? Below are its core practical advantages:
Extreme Temperature Performance
With an estimated useful temperature range from -63°C to 132°C (-81°F to 270°F), Krytox GPL 202 performs reliably in both cryogenic and high-temperature environments. Its medium-viscosity PFPE base oil provides excellent low-temperature fluidity while maintaining high-temperature stability.
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 202 is chemically inert and will not react with virtually all chemicals, including alcohols, ammonia, solvents, steam, acids, and bases. It is non-flammable and safe for use in oxygen service (LOX and GOX).
Radiation Resistance
Krytox GPL 202 provides radiation resistance, making it suitable for demanding applications in aerospace and nuclear environments.
Compatibility with Seals & Elastomers
Krytox GPL 202 is compatible with all types of seals and does not damage plastics or elastomers, nor cause corrosion to metals.
Cost-Effective
Due to their inert nature, Krytox lubricants provide a much longer usable life as compared to typical hydrocarbon oils and greases; and the longer usable life allows them to remain for considerable periods of time before needing to be replaced, if they are replaced at all.
No Additives
Contains no additives, making it suitable for applications where additive interactions must be avoided.
Non-Toxic & Environmentally Inert
Krytox oils and greases are biologically and environmentally inert.

Critical Usage Warnings for Krytox GPL 202:
Temperature Limits: Do not exceed continuous operating temperature of 132°C (270°F). Short-term peak temperatures may be possible.
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.
Food Grade: Krytox GPL 202 is not food-grade compatible (H1). For food-grade applications, consider Krytox H1 series.
Additive-Free: GPL 202 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 202 is insoluble in conventional solvents. Special solvents are required for diluting, cleaning and removing Krytox products.
