These devices are ideal for use in hermetic sealing applications in harsh environments, such as submarines, satellites, underground applications, vacuum chambers, laboratory equipment, and commercial and military aircraft.
Glenair's glass-closure hermetic connectors benefit from high resistance to extreme operating temperatures, from -180°C to +260°C; excellent mechanical strength; and no material degradation or aging over time. The helium leakage rate is very low. All
hermetic connectors are 100% tested before shipment. A helium leak test is performed to certify hermeticity. This test is conducted by inducing a vacuum of 1 ATM 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. The helium leak test takes advantage of the small size of a helium molecule compared to air or water vapor. Helium is inert, rare in our atmosphere, and easily detected with a mass spectrometer.
Glenair manufactures glass-sealed, airtight connectors in the USA and Italy for all Mil and EN standard designs and for new custom designs.
