Backun Signature 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.
*Tip from Hawkins: To re-lubricate signature mouthpiece o-rings, use a drop of almond oil or a tiny bit of cork grease on the inner wall of the barrel top tenon to improve ease of use.
Note: All Backun Signature Series Mouthpieces come with medium-sized O-Rings installed, which fit a majority of clarinet barrel tenons.
