Glass-to-Metal Seal D38999 Hermetics
The MIL-DTL-38999 Series I, II, III and IV family of hermetic connectors are ideal for high-pressure/low-leakage applications in air, sea and space environments. Glenair is on the Qualified Product List (QPL) for all configurations of MIL-DTL-38999 Series I through IV pin and socket hermetic connectors. We also offer our D38999 type commercial part numbers for applications that do not require MS qualified products. And because Glenair makes all its hermetic connectors in-house, including the machining of shells, molding of interfacial seals and firing of hermetic components, we can offer you outstanding availability on stock products and fast turnaround on special orders.

SuperNine Lightweight Hermetic Connectors with CODE RED Encapsulant
"Mission-Critical" Hermetic Sealing with 1x10-7 Leak-Rate Performance
Hermetically-sealed interconnects used in vacuum or high-altitude applications prevent moisture and other contaminants from damaging sensitive electronic equipment. Glass-to-metal hermetic sealing has been the gold standard in the aerospace and petrochemical industries for decades due to the strength and long-term durability of the materials used. But glass-to-metal seal hermetics come with a big price tag in both weight and electrical resistance.
CODE RED is an innovative sealing encapsulant and application process — invented by Glenair — that provides durable hermetic sealing in a lightweight aluminum package. CODE RED allows for the use of conventional gold-plated copper alloy contacts, significantly improving electrical performance. CODE RED hermetic connectors are available now in Glenair SuperNine® (D38999 Series III type), Series 80 Mighty Mouse, and M24308 D-Sub. These connectors deliver reliable, life-of-system 1x10-7 max leak-rate hermetic sealing and special non-magnetic (zero residual magnetism) versions are also available, consult factory.
