Krytox® PFPE in Vacuum Applications

Krytox® performance lubricants are the products of choice for applications where complete nonflammability, oxygen compatibility, and resistance to aggressive chemicals are requirements. These synthetic lubricants provide superior performance and extended life as lubricants and sealants.

xtronix caters to a variety of vacuum and non-vacuum applications with different grades of Krytox® oils and greases. We have addressed aerospace related markets, high voltage industrial applications, paper mills, tribology applications in clean room environments, and many others.

An important area of use for Krytox® relates to vacuum-based applications:
• Vacuum pumps, where safety is critical
• Hostile environments, where semiconductor process chemicals can attack most other lubricants
• Vacuum system valves, seals, bearings and connectors, where low vapor pressure, outgassing, and contamination are intolerable

Tips & Tricks - Vacuum Viewports

This had already been posted back in September 2007 on our old blog and as it had attracted tremendous interest I'm happy to give it a makeover with more detail !

For those who do not often change things on a UHV vacuum system, here's some tips if you need to mount a viewport. First, never use a viewport that appears to be, or is known to be damaged. A replacement viewport costs far less than repairing a system that has been subject of an implosion caused by a faulty viewport.

SAFETY

Pressure differentials: Kodial VPZ viewports are designed to withstand 1 Bar differential pressure. Other standard viewports are designed to withstand 2 Bar differential pressure. The pressure on the ‘vacuum side’ of the viewport must not exceed a positive pressure differential of 1 bar. The viewports are designed for vacuum applications.

• WARNING: Pressures in excess of this or high reverse pressures may cause catastrophic failure and result in serious injury.
