Micro-Tec G4 high-vacuum silicone grease
Micro-Tec G4 high-vacuum silicone grease is designed for sealing and lubrication in vacuum and pressure applications. It is a stiff, non-melting silicone lubricating vacuum grease which maintains its consistency over a temperature range of -40 to 204ºC. Micro-Tec G4 high-vacuum grease is recommended for vacuum systems up to 10-6mbar. It has a translucent white colour and a density of 1.1g/cm3. Its evaporation rate at 200ºC is in the 0.5-1% range. Micro-Tec G4 high-vacuum grease has excellent resistance to mineral and vegetable oils, aqueous solutions of inorganic salts and diluted acids and alkalis.
Due to initial outgassing it is recommended to pre-condition the grease under vacuum and operating temperature until the required vacuum level has been reached
Typical applications include:
- Sealing and lubrication of vacuum components and feedthroughs
- Sealing glass desiccators and lubricating glass seals
- Lubrication of microscope and other O-rings
- Lubrication and sealing of fine threads
- Lubrication of stop-cocks, plug valves, control valves and flow meter bearings
- General lubrication of laboratory equipment
- Lubrication of synthetic rubber gaskets and seals used in high-temperature applications
- Protecting seals in aqueous environments
- Corrosion protection
Krytox GPL 207/206 PFPE / PTFE: inert, vacuum compatible grease
Krytox GPL 207/206 are long-lasting white buttery greases which are nonreactive, nonflammable and safe in chemical and oxygen environments. It contains carbon, oxygen and fluorine but no hydrogen or silicone. Krytox grease will not burn or support combustion. It is an ideal grease for vacuum components which are exposed to air, such as rods in vacuum EM loading locks, vacuum door seals, moving aperture holders and valves. Krytox does not degrade in contact with air and does not contain any silicone and is basically chemically inert.
Krytox GPL 207/206 greases consist of Krytox perfluoropolyether (PFPE) fluorinated synthetic oil and Krytox 2000 polytetrafluoroethylene (PTFE). It also exhibits excellent anti-seize properties. It can be used up to a service temperature of 288°C. Originally a Dupont product, but now manufactured by Chemours, Krytox GPL 207 vacuum grease is an alternative to Braycote 803 and OC Five / OC Seven greases.
Due to initial outgassing it is recommended to pre-condition the grease under vacuum and operating temperature until the required vacuum level has been reached.
Typical applications include:
- Seal and lubricate in oxygen applications
- Seal and lubricate vacuum components
- Seal and lubricate load-lock rods
- seal and lubricate vacuum feedthroughs
- Lubricate O-rings on vacuum systems
- Lubricate seals in aggressive chemical environments

Micro-Tec CSG7 conductive silver vacuum grease
CSG7 conductive silver grease provides a conductive lubrication layer between sliding and sealing surfaces. Features include:
- ESD safe, vacuum compatible lubrication
- Excellent thermal conductivity
- Reduces mechanical wear
- Protects against corrosion from moisture.
Typical applications include lubrication of vacuum transfer rods, airlock systems, moving vacuum feedthroughs, vacuum seals on O-rings, static grounding on seals or O-rings, heat dissipation and lubrication of switches and circuit breakers. Its consistency is paste-like and contains silicon with silver and carbon black for conductivity.
CSG7 grease has a temperature range of -50° to +200°C and is vacuum compatible up to 10-6 mbar. Supplied in a 7g syringe for easy and controlled application.
