Grommet D GD* @ Environmental Protection @ MIL-C-24308 Compatibility @ Reliability and Versatility GD* connectors are ideal for aerospace, military, telecommunications and other applications requir- ing environmental protection and high reliability. ITT Cannon developed GD* connectors to meet the needs of the avionics industry. These connectors provide high-density and moisture protection. Environmental protection is accomplished by the resilient grommet, interfacial seal, and bonded connector components.
