The C47-427 Protective Cap is engineered to protect unmated MIL-DTL-38999 Series I receptacle connectors from environmental contamination and mechanical damage. As part of EMCA’s C4 Series, it provides a reliable protective barrier for the connector’s mating interface—helping maintain the cleanliness and readiness of critical equipment during storage, maintenance and transport.
Precisely machined for compatibility with the 38999 Series I receptacle shell geometry, the C47-427 installs quickly using internal retention features, eliminating the need for tools or mounting hardware. Its secure, friction-based fit ensures effective shielding against dust, moisture and accidental impact.
Manufactured from robust materials and available in corrosion-resistant plated finishes, the C47-427 is well-suited for aerospace, defence, vehicle systems, avionics, industrial controls and other high-reliability environments.
