Anyone know where to find the exact size of the felt washers for a Yamaha YFB822 F tuba? There are two on top of the valve guide and one under the finger button.

Thanks!

You want one styrofoam washer (Yamaha part # G0141150) and one felt washer (Yamaha part # G0141060) under the top cap, and one styrofoam washer (Yamaha part # H1141130) and one felt washer (Yamaha part # H1141100) under the finger button. I have found that the Yamaha tubas do very well with OEM parts, so I suggest sticking with them, since they not only work but are easy to obtain.

The part numbers I quoted are for a 10-pack of the item. Replace the "0" at the end of the number with a "9", and it is a bulk 100-pack, which is what I tend to get for the shop.

Thank you for the responses! My apologies, I should have been clearer - I'm looking for the specs for these washers (i.e.. thickness, diameter, etc.)

This information is helpful also! Thank you!
