The crowns & stoppers are made of zirconium. Both are held in place with an O-ring. 

A simple, cheap and easy-to-install improvement to any flute headjoint. Simply remove the crown and stopper from your headjoint, fit the new stopper, fit the new crown. The difference in sound and response is astonishing.

The crowns & stoppers are made of zirconium.Both stopper and crown are held in place with an O-ring. Flute players are amazed (and I continue to be amazed) how the sound of a flute changes when these gadgets are fitted. Players who use them have said their flutes have become louder, smoother and more responsive.

  • Zirconium stopper with O-ring

Fitting is easy: simply unscrew the original crown and push out the original stopper using the tool supplied. The tool is hollow and will apply pressure to the stopper itself, not to the screw. Next, put the new stopper in the headjoint and push it into position with the tool. The three lines on the tool will help you find the correct position. Finally, push the new crown into position. The whole job takes just a minute


The stoppers will fit almost any headjoint, but the crowns must be made to measure. I need a measurement of the inside of the top of your headjoint (the crown end). Any repair person or engineer will be able to do this for you in seconds using a vernier caliper
