Hetman Synthetic Key Lubricants are specifically designed for musical instrument keys that utilize hinge tube and rod construction. These high technology lubricants provide superior key action by establishing a tenacious, synthetic lubricating film between the hinge rods and hinge tubes. This protective synthetic layer reduces friction and wear, prevents corrosion of hinge rods, dampens sympathetic vibrations, and quiets noisy keys.

The choice of three viscosity grades (Light, Medium, and Heavy) allows the professional to maximize the performance of the instrument's action by selecting the lubricant grade that is best suited to the instrument. The use of the proper viscosity key lubricant ensures an action that is quick, crisp, smooth, and quiet. Hetman Synthetic Key Lubricants are nontoxic, long-lasting, non-gumming, and plastics-safe. Each lubricant is packaged in a 22 ml precision needle oiler dispenser making application simple, neat, and efficient.
