FG-HVG Mini Cleanroom Torque Screwdriver FAQ

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.

Standard Polyurea Grease

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.

Best Used

Waterproof

● ● ● ● ●

Ultra-low outgassing for optimal vacuum performance Consistent lubrication across extreme temperatures Superior chemical resistance in diverse environments Anti-wear properties for extended bearing life

Long operating life Contains no metals

Inhibits rust and oxidation Added resistance to extreme pressure

Features

Performs well in harsh environments

Improved performance over time

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
