Detail 01
Head joint cork
Seals the tube above the embouchure hole. A leaking seal kills low-register response and makes octaves stretch sharp.

Allied Music SupplyFlute Head Cork
Independent shopping perspective
The Korena take
Replacement head joint cork for flute. A consumable part you install when the crown seal leaks or the tuning cork has shrunk and drifts.
Strong match
Who this is for
- Replacing a cork that no longer holds tuning position
- Techs keeping spare consumables on the repair bench
- Flute players whose low register has gone flat and thin
Consider the trade-offs
When to look elsewhere
- Piccolo or other woodwinds — this is flute head joint sizing
- Players unwilling to remove and reset the crown assembly
- Anyone whose intonation problem is embouchure, not hardware
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
Cork, not synthetic
Cork compresses to conform to the bore and can be sanded to fit. It also shrinks over years, which is why it needs replacing.
Detail 03
Consumable part
This wears out on a schedule, roughly every few years of regular play. It's maintenance, not an upgrade.
Detail 04
Under $10
The part is cheap; the fitting is the real cost. Budget for bench time if you're not doing it yourself.
Final check
Know before you order
- 01Sold as the cork only. Crown, reflector plate and rod are not included.
- 02Needs sizing to your bore. Expect to sand or ream it for a proper fit.
- 03Cork position sets tuning. Reset it with a cleaning rod mark after installing.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How do I know my cork needs replacing?
The crown turns too freely, the cork slides when you tune, or your low register weakens and octaves stop lining up. All point to a shrunken or leaking cork.
02Can I install this myself?
Possible with patience. You remove the crown, push the old cork out, size the new one, then set position with the mark on your cleaning rod.
03Does it fit any flute?
Head joint bores vary by maker. Cork stock is meant to be fitted, so expect to sand it down rather than drop it in.
04How often should this be replaced?
Every few years for a regularly played flute. Dry climates shrink cork faster, so check the seal at each routine service.
