Abstract

A glass-to-metal hermetic seal assembly in a viewing glass assembly or hermetic terminal assembly is disclosed, which includes a glass component, an intermediate component, and an outer ring. The intermediate part is arranged around the glass part. The glass part is fused to the middle part. The outer ring, which has a coefficient of thermal expansion greater than that of the glass component, compresses the intermediate component towards the glass component to create a hermetic compression seal.
