Mil-DTL-38999 Series III connector is a high-performance cylindrical connector that is designed for both general purpose and harsh environment applications. It adopts an enhanced "one turn" coupling system and self-locking screw thread to improve the durability of the coupling system, while the thicker wall and larger coupling surface area increase the strength and impact resistance. 38999 Series III connector can also be used for various shell materials and finishes (anode, zinc cobalt, aluminum, electroless nickel plating, olive cadmium, etc.).
