Description

The D38999/32Z13N is a military-standard protective dust cover engineered to safeguard unmated MIL-DTL-38999 Series III connectors against moisture, sand, dirt, and mechanical damage. Manufactured to rigorous aerospace defense standards, this shell size 13 cap ensures mission-critical interconnect assemblies remain clean, conductive, and ready for deployment.

Corrosion Resistance with Class Z Black Zinc Nickel

Designed as a high-performance, environmentally friendly replacement for traditional olive drab cadmium, the Class Z Black Zinc Nickel finish provides superior protection against galvanic and atmospheric corrosion. It withstands up to 500 hours of continuous salt spray exposure, maintains electrical conductivity for dependable EMI/RFI shielding, and complies fully with modern RoHS and REACH directives.

Captive Wire Lanyard Assembly

The unit features an integrated stainless steel wire rope lanyard coated in a protective Teflon jacket to avoid marring adjacent finishes. Terminated with an N-style solid eyelet ring, the lanyard anchors directly to panel-mount hardware or chassis bulkheads, preventing misplacement during maintenance, inspection, and field repair operations.
