Popular, long lasting and odourless, Superslick valve oil applies easily from dropper tip.
2 oz bottle.
Besides lubricating the moving parts of the valve, valve oil provides corrosion protection to the bare metal of the inner valve. While the valve is made of a metal which is more resistant to corrosion, the inner valve casing is typically bare brass. (The brass on the outside of a modern instrument is lacquered or plated to prevent corrosion.) The oil also completes the seal between the valve casing and the piston or rotor.
