8533 Hermetic Series EN2997 & ESC10 Glass-Sealed Circular Connector | Eaton Souriau

Eaton Souriau 8533 Hermetic Series is a family of glass-sealed hermetic receptacle connectors with a threaded coupling qualified to EN2997 and ESC10. The stainless-steel housing ensures reliable mating and long-term performance in extreme environments.

The compact, low-profile design offers high hermeticity and comes in solder-mount, square-flange and jam-nut receptacle styles. It resists high temperatures and vibration, with 200°C and 260°C classes available.

Solder-cup or PC-tail contacts are offered, with selected versions for 230V use and long-term fuel-tank immersion. It is built for aerospace, military and engine-environment applications that need sealing integrity and mechanical robustness.
