Circular Protective Caps and Dust Covers

Mil Spec and Industrial Protective Caps and Dust Covers for Harsh Environments

Dust covers (also known as protective caps) provide environmental protection to the pins of connectors that are exposed when having no cable attached.

PEI-Genesis carries an array of circular dust covers by brands such as Amphenol, Glenair, Sunbank, Polamco and Sure Seal. Dust covers, also known as protective caps, provide high-level protection against live circuits and environmental contaminants in harsh conditions when a connector is not in use, and also increases aesthetics. PEI-Genesis offers many styles of dust covers with a variety of chain connections available in different finishes.

Caps for circular receptacles have internal threads and are used on MS3102, MS3101, and MS3100 Mil Spec type receptacles/connectors. Caps for circular plugs have external threads for use on all plugs where a coupling nut is provided (MS3106 and MS3108).
