On offer for many different connector series from Glenair, the glass-sealed hermetic connector variants resolve gas, moisture and particle ingress problems and feature superior pressure resistance to 32.000+ PSI.
The devices are ideal for use in harsh environment air-tight-seal applications, e.g. submarines, satellites, underground applications, vacuum chambers, laboratory equipment and commercial and military aircrafts.
Glenair’s glass-sealed hermetic connectors benefit from high resistance to extreme operating temperatures from -180°C up to +260°C; excellent mechanical strength and no material breakdown or aging over time. The helium leak rate is very low at <1x10-7cc/sec to 1×10-10 .
All hermetic connectors are 100% tested prior to shipment. A helium leak test is performed to certify the hermetic seal.
This test is conducted by inducing a 1 ATM vacuum on one side of the connector.
Helium gas is released on the other side, and a mass spectrometer “counts” the number of helium molecules that penetrate the connector seal.
Helium leak testing takes advantage of the small size of a helium molecule compared to air or water vapor. Helium is inert, rare in our atmosphere, and is easy to detect with a mass spectrometer.
Glass-sealed hermetic connectors are manufactured by Glenair in the United States and Italy for all Mil- and EN-standard designs and for the new custom designs.
