Hetman Heavy Key Oil #18

Hetman #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. 

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.
