Series C1

EMCA’s C1 Protective Cap Series provides robust environmental protection for unmated circular connectors, safeguarding critical interfaces against dust, moisture ingress, mechanical damage, and contamination during handling, storage, or equipment downtime. Designed to fit securely over plug or receptacle mating faces, these free-fit protective caps help preserve contact integrity and extend connector service life in demanding operating environments.

Engineered for compatibility with widely used connector families—including MIL-DTL-26482 Series I & II and related commercial equivalents—the C1 Series ensures dependable, repeatable fit across a broad range of defence, aerospace, transportation, and rugged industrial systems. Each cap is precision-machined to match the connector’s external interface geometry, providing stable retention without stressing the shell or requiring any panel mounting or hardware.

To support diverse operational needs, C1 caps are available for both plugs and receptacles, with options for tethering/lanyard features, varied material constructions, and corrosion-resistant finishes matched to harsh-environment interconnect systems.

Whether used in field maintenance kits, production test environments, or long-term storage applications, the C1 Protective Cap Series delivers a simple, reliable, and cost-effective means of preserving connector readiness and ensuring consistent system performance.
