Frequently Asked Questions
What makes Krytox GPL205 different from standard greases?
Krytox GPL205 is a fully synthetic, PTFE-thickened grease with no hydrocarbon base oil or additives. Unlike conventional petroleum-based greases, it is nonreactive, nonflammable, and chemically inert — making it safe for use in oxygen systems, chemical processing equipment, and applications where standard greases would degrade or create contamination risks.
Is Krytox GPL205 safe for oxygen service?
Yes — Krytox GPL205 is nonreactive and nonflammable, making it suitable for oxygen system lubrication where hydrocarbon-based lubricants would pose a fire or explosion hazard. Always verify your specific oxygen system requirements and applicable standards before use.
What is the operating temperature range for GPL205?
Krytox GPL205 retains its lubricating properties from -36°C (-33°F) to 204°C (400°F), making it suitable for both low-temperature and elevated-temperature bearing and valve applications where standard greases would harden, melt, or oxidize.
Can GPL205 be used on O-rings and seals?
Yes — GPL205 is commonly used on O-rings, seals, and valves, particularly in chemical and oxygen service applications. Its chemical inertness means it will not degrade most elastomeric seal materials or react with process media.
What is the difference between Krytox GPL205 and other Krytox 200 series greases?
The Krytox 200 series greases share the same PTFE-thickened, additive-free synthetic base but differ in viscosity grade. GPL205 is a general-purpose grade suitable for a wide range of bearing and valve applications. Higher or lower viscosity grades are available for specific load, speed, or temperature requirements.
