Which mouthpiece cap fits my clarinet?
A good mouthpiece cap is essential for protecting both your mouthpiece and reed. Whether you're looking for a cap for Bb clarinet, bass clarinet or another model, the right choice keeps your reed in top condition and helps prevent damage.
Caps protect not only the mouthpiece and ligature but also keep the reed moist, so it doesn't dry out too quickly. Want to ensure the perfect fit? Choose a ligature that includes a matching mouthpiece cap.

How to Choose the Right Mouthpiece Cap for Your Clarinet
Selecting a suitable clarinet mouthpiece cover depends on your instrument, mouthpiece, and ligature type. There are important differences you should know:
Ebonite versus Crystal Mouthpieces
- Mouthpiece caps for ebonite mouthpieces are narrower than for crystal mouthpieces. A plastic mouthpiece cap or metal mouthpiece cap must therefore fit your mouthpiece type.
- The ligature opening is wider for fabric ligatures than for metal ligatures. For optimal mouthpiece cap compatibility, you must consider both your mouthpiece and ligature.
Universal vs. Brand-Specific
The most important thing is to look at your ligature brand and match it with your clarinet mouthpiece cap. BG mouthpiece caps are usually universally usable.
Browse below by instrument type (Bb clarinet, A clarinet, Alto clarinet, Eb clarinet, Bass clarinet, Contrabass clarinet), mouthpiece material (metal / crystal), and ligature type (fabric / metal) to find your perfect match.
