Differences Between Standard Polyurea Grease and Ultra-High Vacuum Grease
While Mountz Cleanroom tools are designed to confine grease, there remains a minor chance of grease vapors escaping through the seals when conventional grease is utilized. For highly sensitive applications in Ultra-High Vacuum and Optics fields, we provide a specialized grease characterized by remarkably low vapor pressure and sustained lubrication performance.
The Mountz Cleanroom FG screwdrivers feature a polyurea Grease, which is utilized in all FG standard models. However, customers have the option to upgrade to a High-Vacuum PFPE Grease for an additional cost.
The Ultra-High Vacuum Grease is crafted using advanced polytetrafluoroethylene (PTFE). It's characterized by ultra-low outgassing, vast temperature suitability, and superb lubrication. Being chemically inert, non-toxic, and nonflammable, it stands out as an ideal choice for diverse chemical interactions.

Ultra-High Vacuum Grease
Color
Blue Green
Translucent White
Operating Temperature
-40°C to +276°C
-20°C to +325°C
For applications where the external elements in the field cannot always be controlled, such as a high temperature spike or extreme weather conditions.
For highly sensitive applications in ultra- high vacuum.

Tools with standard grease have 4xISO compliance with a Calibration interval of 20K cycles, except the FG-25z and FG-50z models which meet ISO standards.
Tools with HVG have reduced recommended Calibration (5k) and Service (50k) intervals compared to the standard grease FG tools. Fluorinated solvent cleaners such as: ● MS-250M PFPE Re-move ● Castrol Brayco IC X-100 ● TorrLube Solvent TS-86 ● TMC-HFE-367E
