Ultra-Pure Linkage, Lever and Key Oil is used for rotary valve mechanical linkages, ball joints, levers, keys, triggers, etc. It is excellent on all threaded parts, such as valve cap threads and threaded bells. Use also as woodwind key oil for clarinet, saxaphone, flute, oboe, bassoon, etc. Since it is a thicker oil, it will last a very long time and will protect metal-to-metal joints.
Usage info: Place a few drops on the ball joints, hinges, levers, or other metal-to-metal connections of rotary valves and woodwinds. If you use it on a woodwind instrument, be sure to use just a tiny bit and be careful not to get oil on the pads. See our blog post on oiling rotary valves for more info.
