Protective caps

Protective caps for circular connectors are mechanical covers designed to protect the mating surfaces and contact points from environmental contaminants and physical damage when they are not in use. These caps typically screw onto the connector, ensuring a secure and tight fit and are crucial for maintaining the integrity, performance, and longevity of connectors in a wide variety of industries, including military, aerospace, industrial, and medical fields.

We offer caps for receptacles and plugs for all the major connector series with corresponding body materials and plating finishes. Many are available with an optional lanyard or retention tether that attaches the cap to the connector, preventing the cap from being lost when not in use.
