Hetman No. 3 Classic Piston Valve Oil ? 2 oz.

Hetman No. 3 Classic Piston Valve Oil is a synthetic lubricant designed for older brass instruments, looser valve tolerances, or valves that need a slightly heavier oil to seal and move smoothly. The classic formula gives players more cushion than lighter oils, helping reduce noise and improve feel on instruments with more wear. This is a useful choice for vintage trumpets, older euphoniums and tubas, school instruments, or any piston-valve brass instrument where light oil disappears too quickly. It is especially helpful when the valves are clean but still feel a little loose or noisy.
