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.
16. LIGHT KEY - A light viscosity synthetic lubricant formulated for instruments with close tolerance actions. Frees sticking keys by penetrating into hinge tubes. Provides for a smooth, quick action.
17. MEDIUM KEY - The preferred key lubricant for most instruments. The viscosity of this synthetic is best suited to actions of average tolerance. Keeps keys moving quickly, smoothly, and quietly.
18. HEAVY KEY - A synthetic key lubricant engineered for instruments with worn actions and instruments that characteristically exhibit greater action tolerance. Quiets noisy keys and dampens sympathetic vibrations without slowing the instrument's action.
