Hetman Piston Classic #3 (A7233)

Apologies for the confusion in my previous response. The Hetman Piston Classic #3 (A7233) is a specific valve oil designed for lubricating and maintaining the pistons of brass instruments such as trumpets, cornets, and flugelhorns.

Hetman Piston Classic #3 is formulated with a medium viscosity to provide excellent lubrication and sealing properties between the piston and valve casing. It helps reduce friction and wear, allowing for smooth and responsive valve action.

To use the Hetman Piston Classic #3, you would typically apply a small amount of oil directly onto the piston, ensuring even coverage on all sides. It's important to use the oil sparingly to avoid excessive buildup or leakage.

Regular application of the Hetman Piston Classic #3 lubricant helps ensure optimal performance and longevity of the piston valves. It's always recommended to follow the manufacturer's instructions or consult with a qualified instrument technician to ensure proper usage and maintenance techniques specific to your instrument.

Please note that product details and availability may have changed since my last update in September 2021. It's advisable to refer to the manufacturer's information or consult with a reputable music store for the most up-to-date product specifications and availability.
