Due to product availability, we are no longer offering Hetman Valve 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 piston lubricants can be used on trumpets, baritones, and tubas. This valve oil will allow piston valves to have an action that is smooth, quick, and consistent.
