Amphenol Martec Mil-Spec Hermetic Connectors

Amphenol Martec’s UK-engineered MIL-Spec hermetic connectors deliver proven performance in the harshest conditions. Designed for both general duty and severe environment applications, these connectors maintain complete system integrity even under high pressure, vacuum, or rapid temperature changes.

The D38999 series meets the stringent MIL-DTL-38999 specification, combining high-density contact arrangements with a compact, lightweight shell. Hermetic sealing is achieved through advanced glass-to-metal technology and ensures zero leakage, making them ideal for aerospace, defence, and industrial systems requiring gas-tight barriers or resistance to extreme environmental stresses.  Martec’s designs feature a three-point bayonet lock system and five keyway orientation, eliminating the risk of mismating while ensuring quick, secure coupling. These precision-engineered interfaces also provide exceptional electrical performance, including EMI/RFI shielding and minimal signal loss.

With a wide choice of shell styles, materials, plating finishes, and pin configurations, the D38999 hermetic range can be tailored to meet exact design requirements. Options are available for both standard and custom applications, from avionics to fuel systems and sensor housings.

As an authorised Amphenol Martec distributor, Aerco supports customers from specification through to delivery, providing the technical insight needed to select the right connector for mission-critical projects.  Whether for defence, aerospace, or high-reliability industrial systems, the D38999 hermetic connector series delivers the durability, precision, and performance your application demands.
