Extra-fine, high-fluidity lubricant for smooth and precise piston action.
GB Tool Extra-Fine Piston Lubricant was developed for the maintenance of brass instruments equipped with piston valves. Its lightweight, highly fluid formulation helps reduce friction between the piston and valve casing, providing smooth, fast and consistent movement.
Ideal for trumpets, cornets, euphoniums, tubas and other piston-valve brass instruments.
With the piston clean and dry, apply a few drops of lubricant to its surface. Spread evenly and reinstall the piston. Avoid excessive application.
