Plugs, receptacles and accessories manufactured from stainless steel or light aluminum alloy with black anodized (non-conductive plating), nickel plating (conductive plating), olive drab or yellow cadmium (conductive plating).

Gold plated crimp contacts are removable from the rear and retained by metallic clips. Mini-coax and thermocouple contacts may also be installed instead of standard contacts.

The hard insulator is a thermoplastic material. The insulators are fluid resistant as specified by MIL-C-26482G Series II / HE302 / EN3646, including Standard norms coming from earlier norms NFL54130 / NAS1599 / LN29504.

Front and rear silicone elastomer parts provide an effective seal between connector and cable and also at connector interface.
