Amphenol’s hermetically sealed 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.

 

What applications are hermetic connectors used in?

Hermetic connectors are ideal for extreme environments in military and commercial applications, including:

 

  • Military aviation
  • Naval ships and submarines
  • Missile systems
  • Low Earth orbit (LEO) satellites
  • Onshore and offshore drilling
  • Automotive race fueling
