Category: Vacuum Seal and Lubricant

Seal material can be used to repair small leaks and for fixturing of 2 components. In both cases it’s important to have a low outgassing rate, and a perfect leakrate.

Lubricants are used in a vacuum system for three reasons:

* to lightly grease the O-ring so it will move, seat, and seal better.

* to reduce the friction coefficient, wear rate, and particulate generation.

* as an anti-seizing agent on nuts and bolts.

The choice of a lubricant depends on:

* operating temperature and vapor pressure

* sliding motion or rolling motion

* reactive gas, electron beam, or plasma ambient

* heavy or light loading

* extensive repetitive usage or moderate use.
