CEC Series Conductive Caps

Caplugs CEC Series Conductive Caps are designed for threaded and non-threaded connectors. The CEC conductive caps support all common sizes of threaded electrical and electronic connectors. These series caps are suitable for protecting non-threaded and bayonet-type connectors. The CEC caps provide an electrical shield over the end of the connectors to dissipate electrostatic charges. These conductive caps from Caplugs are made of Conductive Polyethylene Copolymer (EVA) material and are available in black color.
