This is a group of premier lubricants for rotary valves. These are designed and manufactured in the USA by Joe Hetman. Hetman synthetic lubricants have a very smooth molecular structure. These lubricants are especially slippery, do not build up, resist corrosion, and last a long time. You'll need fewer applications of Hetman than of most other brands.
If you choose one from each group below, you will have very happy and smooth rotary valves.
All are packaged in a 22ml bottle with a long tipped needle oiler.
The first group is rotor lubricants designed for use inside the rotor. Drip these down your second slide on a double horn or rotary trumpet, down the leadpipe on a tuba, or into the bell connector on a trombone.
The second group is three bearing & linkage lubricants to be used for anything external, like rotor spindle bearings, pivot bridges, linkage pivots, and the back bearing under the rotor cap.
This Ball Joint lubricant is optional depending on your horn's condition. Those with rattly worn instruments know who you are.
