Description

Protect unmated circular connectors from environmental contamination, physical damage, and signal degradation with the D38999/32Z9R receptacle dust cap. Manufactured to rigorous MIL-DTL-38999 Series III standards, this heavy-duty protective cover ensures reliable contact sealing and connector longevity in high-reliability military and industrial systems.

Featuring high-grade aluminum construction with Class Z Black Zinc Nickel plating, the D38999/32Z9R offers an environmentally friendly, RoHS-compliant alternative to Cadmium plating. It provides exceptional corrosion resistance (500-hour salt spray endurance) alongside excellent conductive EMI/RFI shielding. The integrated wire rope lanyard with a Ring terminal tethers the cap securely to your panel assembly, eliminating the risk of lost hardware during field service.
