Circular Protective Caps and Dust Covers

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.
