Hermetic Connectors


Esterline Connection Technologies - SOURIAU provides hermetic connectors based on glass to metal seal technology. We have developed our own glass-to-metal sealing technology to deliver the highest performance, enabling very high sealing and reliability to critical missions such as space programs and aviation applications.

Our solution

Capability description

A connector is defined as hermetic when the air leakage between its 2 faces is below 1.10-7atm.cm3/s under 1 atmosphere difference. Follow this link to browse our catalogue of hermetic connectors.

Scale examples: under 1 atmosphere pressure difference, 1 cm3 leaks in:

  • 1.10-4atm.cm3/s: 3 hours under 1 atmosphere
  • 1.10-7atm.cm3/s: 4 months under 1 atmosphere
  • 1.10-9atm.cm3/s: 30 years under 1 atmosphere
