Environmental Testing
EESeals Withstand the Harshest Environments
EESeal® and EESeal+® are designed to withstand extremely harsh conditions. They meet or exceed the environmental requirements of most military and commercial connector specifications (e.g., D38999). These environmental and mechanical tests were conducted by independent laboratories with EESeals® mounted inside D38999 connectors showing that severe environments do not affect the integrity of EESeal® or the host connector. The testing below was completed for EESeal+® and Hybrid EESeals®.
