    Conductive Caps

    Image of Product. Front orientation. Protective Caps. Conductive Caps.
    Shield electrical connectors from interference and static while keeping out dust. These caps have a surface resistivity of less than 105 ohms/sq. to block stray signals and dissipate static charges much more quickly than antistatic caps. They protect threaded and unthreaded connectors during shipping and storage.
    Polyethylene—These tough caps are hard and wear resistant to hold up against scrapes and gouges.

    Conductive Plugs

    Image of Product. Front orientation. Contains Annotated. Protective Plugs. Conductive Plugs.
    Shield electrical connectors from interference and static while keeping out dust. These plugs have a surface resistivity of less than 105 ohms/sq. to block stray signals from nearby equipment. They also dissipate static charges much more quickly than antistatic plugs. Use them to protect threaded and unthreaded connectors during shipping and storage.
