Description

The D38999/32F25N is a military-standard protective cover engineered to shield unmated MIL-DTL-38999 Series III plug connectors from physical damage, environmental debris, and electromagnetic interference. Manufactured to rigorous aerospace and defense specifications, this shell size 25 dust cover maintains connection integrity and prevents contact deformation in mission-critical electrical systems.

Constructed from high-grade aluminum alloy, the assembly features an Electroless Nickel (Class F) conductive finish. This provides excellent corrosion resistance, fluid resistance, and robust EMI/RFI shielding continuity across wide operating temperature bands.

The integrated wire rope lanyard ensures the cap remains captive to the equipment housing, preventing loss during field operations and routine maintenance cycles.
