The C47-426 Protective Cap provides dependable environmental shielding for unmated MIL-DTL-38999 Series I plug connectors, ensuring the exposed mating face remains protected from dust, moisture, foreign objects and mechanical impact during non-operational periods. Part of EMCA’s rugged C4 Series, it preserves the connector’s critical interfaces and supports long-term system reliability.
Designed specifically for the 38999 Series I bayonet-coupling profile, the C47-426 fits securely using internal retention features, enabling fast, tool-free installation in both field and workshop environments. Once fitted, it creates a protective barrier that prevents contamination and reduces wear on the plug insulator and contact area.
Constructed from durable materials and available with corrosion-resistant finishes, the C47-426 is suitable for aerospace platforms, defence electronics, ground systems, industrial machinery and other harsh-environment applications.
