KLUBERTEMP GR AR 555 1KG High-Temperature PFPE Grease for Valves and Bearings
Product Overview
KLUBERTEMP GR AR 555 is a specialty high temperature grease developed using perfluorinated polyether (PFPE) base oil and PTFE thickener. It is engineered to provide long-term, reliable lubrication under extreme thermal and chemical stress, making it ideal for industries such as semiconductor manufacturing, chemical processing, and automotive systems.
Key Features & Benefits
Excellent thermal stability up to +260°C
Chemically inert – resistant to aggressive media and oxidants
Suitable for oxygen environments (e.g., valve lubrication)
Extremely low evaporation loss at high temperatures
Compatible with most plastics and elastomers
NSF H1 registered for incidental food contact (if applicable)
Applications
KLUBERTEMP GR AR 555 is recommended for PTFE grease applications involving valves, fittings, sliding surfaces, and high temperature bearings exposed to reactive gases or aggressive media. It is widely used in cleanrooms, chemical plants, and food or pharmaceutical machinery where long term lubrication and chemical resistance are critical.
