Spectrum Visual Lubrication Management System

The washers are part of the Spectrum Visual Lubrication Management System that uses color-coding to ensure the correct grease is used in the right piece of equipment and in the proper location. Colored identifiers are assigned to designated greases, which allows for a tagging system to be deployed throughout the Journey of the Lubricant. From the point of storage to the point of application, the operator will know which designated grease is to go to each specific grease point.
