描述
Krytox GPL 103 is a medium viscosity PFPE (Perfluoropolyether) general purpose oil, 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 clear, colorless fluorinated synthetic oil is an ISO Grade 32 oil with a viscosity of 30 cSt at 40°C. It is part of the Krytox GPL 100–107 series of general purpose oils and contains no additives, making it exceptionally pure and suitable for the most demanding applications.
Krytox GPL 103 is a perfluoropolyether (PFPE) – also called perfluoro-alkylether (PFAE) or perfluoropolyalkylether (PFPAE). The polymer chain is completely saturated and contains only carbon, oxygen, and fluorine. On a weight basis, a typical Krytox oil contains 21.6% carbon, 9.4% oxygen, and 69.0% fluorine.
Krytox GPL 103 is non-reactive, non-flammable, safe in chemical and oxygen service, and long-lasting. Compared with Krytox GPL 102, GPL 103 has higher viscosity (30 cSt vs. 15 cSt at 40°C) and thicker oil film retention. Compared with higher-viscosity grades such as GPL 104, GPL 105, GPL 106, and GPL 107, GPL 103 still maintains good fluidity and is suitable for medium-load, medium-speed, and precision lubrication applications.
With regular stock availability, we support both trial orders and large‑volume bulk shipments for automotive, industrial, aerospace, and demanding applications.

Material Advantages of Krytox GPL 103
What makes Krytox GPL 103 the preferred choice for medium viscosity and demanding lubrication applications? Below are its core practical advantages:
Medium Viscosity – Thicker Oil Film with Good Fluidity
With an ISO Grade 32 and viscosity of 30 cSt at 40°C, Krytox GPL 103 offers a thicker oil film for improved lubrication retention while maintaining good fluidity. Compared with GPL 102, GPL 103 has higher viscosity and better oil film retention, making it more suitable for medium-load and medium-speed components. Compared with higher-viscosity grades, GPL 103 still maintains good fluidity for precision lubrication applications.
Extreme Temperature Performance
With an estimated useful temperature range from -60°C to 154°C (-76°F to 310°F), Krytox GPL 103 performs reliably in both cryogenic and elevated temperature environments. The pour point of -60°C provides excellent low-temperature fluidity.
Chemical Inertness & Non-Flammability
Krytox GPL 103 is chemically inert and does not easily react with most acids, alkalis, solvents, oxidizing gases, or chemical media. 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.
Extended Lubrication Intervals
Krytox GPL 103 exhibits significantly longer-lasting lubrication than mineral oil–based technology. This translates to extended lubrication intervals, reduced maintenance costs, and increased equipment life.
Compatibility with Seals & Elastomers
Krytox GPL 103 is compatible with all types of seals, O-rings, valves, and seals, and does not damage plastics or elastomers.
Silicone-Free & Environmentally Inert
Krytox GPL 103 does not contain silicone, making it safe for sensitive applications. It is biologically and environmentally inert.
