High Vacuum Sealant
Low vapor pressure resin sealant for sealing leaks
Loctite Epoxi-Patch Kit
Useful to 1x10-9 Torr. Forms strong bond with glass, ceramic and metal. Hardens at room temperature. Contains no solvent. Max. bake temperature is 125 °C.
Celvaseal
Silicone resin, useful to 1x10-11 Torr. Much less weight loss compared to Loctite after bake. RGA indicates no evidence of hydrocarbons or other contaminations. Withstands repeated temperature cycling from -200 °C to 450 °C over long intervals of time.
High Vacuum Lubricant
High vacuum grease and lubricant has low vapor pressure. Generally used to wet O-Ring to improve sealing when ultra vacuum is not required. Also used on threaded fasteners to keep from sticking inside a vacuum environment.
