Hermeticity is generally defined as the state or condition of being air or gas tight.  In interconnect applications, hermetic refers to packaging technology designed to prevent gases from passing through pressure barriers via the connector.  The classic hermetic application is a receptacle feed-through penetrating a pressurized bulhead or a pressurized equipment housing.

Complete Hermetics designs and manufactures custom prototypes for hermetic seals & feedthroughs. Complete Hermetics manufactures glass-to-metal seals and electrical feedthroughs as well as custom ceramic-to-metal feedthroughs.
