Backun Bb Mouthpiece O-Ring Set
This set of three replacement O-Rings fits Backun Signature Bb Clarinet Mouthpieces. Available in three sizes (small, medium and large), the O-Rings are self-lubricating, which reduces friction when assembling the clarinet.
Note: All Backun Signature Bb Clarinet Mouthpieces come standard with the medium size O-Rings installed on the mouthpiece, as well as supplemental small and large sets.
