Due to product availability, we are no longer offering Hetman Rotor Oil. After several months of in-house research and testing, we have found the Ultra Pure products to be the most comparable to Hetman products. Our own repair technicians have made the switch to Ultra Pure, and we feel confident in recommending their synthetic oils. Please click here to order the right Ultra Pure product for you: Ultra Pure Valve/Roto Oil Hetman synthetic rotor lubricants can be used on French horns and trombones that have F-attachment rotors. These rotor lubricants provide for long-lasting rotary valve performance and will not swell rubber bumpers or damage plastic components.
