Amphenol Hermetically Sealed Connectors

Amphenol Hermetic Connectors offer superior electrical performance with the rugged design of a glass-sealed or epoxy-sealed connector and exceptional leak rate performance. Amphenol glass-sealed hermetic connectors are available in a variety of Mil-Spec configurations, and we offer custom designs for any harsh environment. Our epoxy-sealed connectors are a lightweight alternative to glass-sealed hermetic connectors.

What is Hermetically Sealed?

Applications that need to keep out the elements should consider opting for hermetically sealed connectors. These special connectors feature an airtight vacuum seal that prevents liquid, air, gas, and solid particles from entering the contact space. With a hermetic seal built to sustain strict leak rates, hermetic connectors prevent seal penetration and can withstand high pressures and maintain stable pressure differentials. 

Both glass-to-metal seal and epoxy seal connectors offer an excellent airtight seal. Various environmental and application factors will determine which type of seal is best for your needs.
