EMCA’s C3 Series Protective Caps provide high-performance environmental protection for unmated MIL-DTL-38999 Series III circular connectors. Engineered for compatibility with these widely used high-density, high-reliability connector systems, C3 caps protect both plug and receptacle interfaces from dust, moisture, debris and mechanical impact in demanding operational environments.
Designed for rapid installation without tools, the C3 caps fit directly over the connector’s mating face using their internal retention features. This ensures secure engagement while enabling easy removal during maintenance or reconnection. Manufactured from robust materials and offered with corrosion-resistant plating options, the C3 Series delivers long-lasting durability for aerospace, defence, military vehicle, avionics bay, naval, and rugged industrial electronics applications.
By shielding critical mating surfaces and contact zones during storage, handling, transport and equipment downtime, C3 caps help preserve connector integrity and extend the service life of MIL-DTL-38999 Series III assemblies.
