MIL-DTL-38999 Series I, II, III and IV Qualified Hermetic Connectors

Hermetic Connectors

The Full Range of MIL-DTL-38999 Series I, II, III and IV Hermetic Receptacles — Plus Glenair Commercial Equivalents

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.

Same-Day Inventory

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.
