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 protection against live circuits and environmental contaminants when a connector is not in use. 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 receptacles.
