Geoscience High Temperature and Pressure Flanged Sight Glass, Metal Seal

Sapphire Window in C-Sealed housing, 600bar. A copper Conflat gasket is shown as an option to seal the main assembly to the process vessel. Conflat gaskets are inexpensive and effective in vacuum applications at bake-out temperatures up to 500°C. This is a clean metal-to-metal sealing solution for semiconductor and pharmaceutical industries. Not recommended in high pressure applications. | Photo credit: Encole LLC
