Hetman No. 1 Light Piston Valve Oil ? 2 oz.

Hetman No. 1 Light Piston Valve Oil is a synthetic piston lubricant designed for close-tolerance valves that need fast, clean action. The lighter formula is a good match for newer brass instruments, tighter valve casings, and players who prefer a quick valve feel without a heavier oil slowing things down. This is a strong choice for trumpet, cornet, euphonium, baritone, and other piston-valve brass instruments with valves in good condition. Hetman piston lubricants are known for smooth action, corrosion protection, and non-gumming performance when used on clean valves.
