How to grease a high vacuum o-ring?
Use a minimal amount of vacuum (silicone) grease. Just enough to make it shine. Grease collects dirt and dust leading to vacuum leaks.

Typically if maintained well the life expectancy of a vacuum furnace should be 30 years or more. The critical component is the vessel. It is like the foundation of a house, and if maintained it will last a long time. Cooling water quality is critical to vessel life and longevity. All other compoRead more

See lessWhy is vacuum grease needed on o-ring installations?
Vacuum grease is not "needed" on o-rings to make a vacuum tight seal. Vacuum grease provides two things, 1) lubrication to allow for easier installation of the o-ring. 2) lubrication to allow movement of the sealing surfaces during evacuation. Grease is actually a detriment, as it collects dirt thaRead more
