The Glenair D38999/33W21R is a protective dust cap designed for use with MIL-DTL-38999 Series III receptacles, shell size 21. The cap is constructed from olive aluminum with a 1000 Hour Grey nickel-PTFE (Ni-PTFE) plating (plating code MT). This advanced plating delivers outstanding corrosion resistance with 1000 hours static and 500 hours dynamic salt spray protection, while maintaining a maximum shell-to-shell millivolt drop of 2.5 mV for electrical continuity. The cap includes a metal chain for secure tethering, preventing loss during handling or storage.
Environmental performance includes an operating temperature range of -55°C to 175°C and support for 500+ mating cycles. The plating is cadmium-free and hexavalent chromium free, making it RoHS compliant. The non-reflective, non-magnetic olive finish is suitable for tactical military systems requiring EMC performance.
This dust cap is ideal for protecting connectors in land, sea, air, and space applications, ensuring longevity and reliable performance in harsh environments. It is a direct accessory for Glenair MIL-DTL-38999 Series III receptacles and is compatible with other manufacturers' similar connector systems.
