Fluorolube GR-290 Perfluorocarbon Grease

Description

Fluorolube GR-290 is a heavy-grade perfluorocarbon grease for oxygen service, chemical processing, and applications requiring full inertness to aggressive oxidizers and halogens. Formulated with a PCTFE polymer base and PTFE thickener, GR-290 provides stable lubrication where conventional greases would react, ignite, or degrade.

GR-290 Benefits

• Fully inert to oxygen, halogens, and strong oxidizing agents — rated for oxygen-enriched service
• Non-flammable under normal operating conditions, reducing fire risk in hot oxygen and reactive gas environments
• PTFE thickener maintains stable grease structure across a wide service temperature range
• Low volatility and vapor pressure support use in vacuum systems and enclosed process equipment
• Compatible with most metals, fluoropolymer seals, and plastics used in industrial fluid handling

Common Applications

• Oxygen valve and fitting lubrication in industrial gas and medical oxygen systems
• Thread and gasketing lubricant for high-pressure oxygen service piping
• Chemical pump bearings and mechanical seals in halogen and oxidizer environments
• Cryogenic valve packing where conventional greases fail at low temperatures
• Vacuum system lubrication where outgassing and reactivity are concerns

Surface Prep and Use

Clean contact surfaces with a compatible solvent such as alcohol or ketone and allow to dry before application. Apply a thin, uniform film to mating surfaces, threads, or bearing races. A light coat is sufficient to establish the lubricant film. GR-290 remains stable over long service periods without migration or separation.
