SILKOPEN is a graphited penetrating spray designed to ease the dismantling of seized and rusted fasteners by penetrating deep into threads. Its powerful formula also reduces friction and provides smooth operation, making it an essential tool for other maintenance tasks including cleaning and lubricating cables. When used with a cable oiler, SILKOPEN penetrates the full length of the cable, forcing out dirt and corrosion, leaving a thin graphite and oil lubricating film for a silky smooth lever action.
