French Horn & Tuba Rotary Valve Bumper Stop, 3/16" Natural Cork Stick

Exactly what I needed. Once I got the diameter worked out. Your help with the bumper stop was much appreciated.

Quick service and parts fit as expected.

Perfect fit for my Conn 8D. Once cut to height, getting it into the slot was initially difficult until I squeezed it narrower with a needlenose, then worked each into place. Once in place, no trimming was required, all the rotor index marks lined up perfectly. My lucky day 😉
