Yamaha Synthetic Rotor Oil

Yamaha synthetic rotor oil is more consistent than traditional oils, giving it better stability in different temperatures. In addition to a smoother feel, you will also be adding to the life of your instrument thanks to a powerful corrosion inhibitor contained in the oil. The weight of the oil is ideal for the internal surface of rotary valves, such as French horn, F-attachment or bass trombone rotors, or rotary valve tubas.
