Silkolene Silkopen penetrates oxidized or seized threads and provides lubrication for easy disassembly by reducing the required torque. It is composed of very fine particles of graphite in suspension. In combination with a cable lubricator, it penetrates completely through the sheath, repels all impurities and thus protects the treated elements from corrosion. It leaves a thin film of oil and graphite that provides excellent lubrication.
