With Amphenol's new Air-Tight Lightweight Hermetic connectors, there’s no longer a need to sacrifice weight to provide a high-quality hermetic seal and operating temperatures. Utilizing high-performance materials, these hermetically sealed connectors will meet a leak rate of 1x10-7cc helium per second and maintain an operating temperature of -85 °F (-65 °C) to 392 °F (200 °C). 

This revolutionary design utilizes an aluminum shell resulting in a weight savings of 35 percent across any shell size. No more concerns about introducing traditional, heavy, stainless steel hermetics and sacrificing your application's performance.

Currently offered in any standard MIL-DTL-38999 configuration with the option to implement in other connector series where appropriate. Contact your local Amphenol representative for more information.
