Three nontoxic viscosity grades are available in 60 ml controlled dropper tip bottles:
PISTON - Designed for instruments with piston valves having average clearance
What can I say, it’s Hetmans, simply the best I’ve ever used.
I used 3 viscosity for my older horns, 2 for newer ones. It’s long life, doesn’t gum up or wear off easily.
Hetmans has never let me down.
Thanks for the great service !
This is an excellent valve piston oil. I have trusted this for many years, and if I ever get sticky valves, I know it's not the fault of this oil. Highly recommended.
