Detail 01
Tenor sax sizing
Tenor mouthpieces are noticeably larger than alto. An alto cap won't seat, and this will slide off an alto.

Independent shopping perspective
The Korena take
A plastic cap that covers the reed and tip of a tenor sax mouthpiece. Replacement part for a lost or cracked cap.
Strong match
Who this is for
- Replacing a cap lost in a case or at rehearsal
- Students who leave a reed on the mouthpiece between sessions
- Keeping a spare in the case so the reed tip stays protected
Consider the trade-offs
When to look elsewhere
- Alto, soprano, or baritone mouthpieces — this is sized for tenor
- Players wanting a metal cap for durability or feel
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Plastic construction
Light and won't dent a reed on contact, but it can crack if stepped on or crushed in a case.
Detail 03
Cap only
No ligature included. The cap slips over a mouthpiece with the ligature and reed already on.
Detail 04
Under $10
Cheap enough to keep a backup. Losing one shouldn't mean leaving a reed exposed for weeks.
Final check
Know before you order
- 01Ligature is not included — this is the cap by itself
- 02Cap fit varies with ligature bulk; a thick metal ligature can make it tight
- 03Confirm your mouthpiece is tenor, not alto, before ordering
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my alto sax mouthpiece?
No. This is sized for tenor saxophone mouthpieces, which are larger. An alto cap is a separate part.
02Does it fit non-Yamaha mouthpieces?
It fits mouthpieces close to Yamaha's tenor dimensions. Larger hard rubber or metal pieces, or bulky ligatures, may be a tight or loose fit.
03Does it come with a ligature?
No. This is the cap only. The ligature that holds your reed is a separate item.
04Why do I need a cap at all?
It protects the reed tip and the mouthpiece rails, which are the two easiest things to chip. A chipped reed tip is unplayable.
