I have a Besson Sovereign BE943 Bass Trombone with dual Hagmann valves. The "O" rings for the valves do wear out over time. Does anyone know a reliable source for replacing them? Thanks.

You can buy them from the Rath Trombones shop https://johnpacker.co.uk/products/o-rin ... mann-valve

Dillons Music usually has them.

Mouthpiece Express and Hickeys also carries them:
