For lubricating the spindle bearings on both ends of rotary valves on brass instruments. Light bearing is best for instruments with close fitting spindle bearings. It provides the maximum protection without slowing the action. Heavy (Bearing & Linkage) is a slightly heavier lubricant engineered to combat the wear and stresses encountered by rotary valve spindle bearings, linkage joints, cross joints, and lever hinges. Plastics-safe. Precision needle applicator. 25 ml.
