Whistle Fox40 jaw single silicone model 5906 by Fox40

Single silicone replacement jaw for Fox40 whistle model 5906 is a removable mouthpiece component designed to restore the contact surface and user feel of compatible Fox40 single-pea and pealess whistles. Made of soft silicone, the jaw fits into the whistle’s mouth aperture to renew hygiene, improve comfort, or adjust the tactile response without altering the whistle’s acoustic mechanism. The part is intended for field maintenance and simple user-level replacement when the original mouthpiece shows wear or requires sanitary renewal.

Advantages

The silicone jaw offers a hygienic, easy-to-clean surface that resists cracking and deformation compared with some hard-plastic mouthpieces. Its flexible material provides a gentler contact point for the lips and teeth while maintaining the original whistle ergonomics. Installation and removal are straightforward, enabling fast replacement to keep the whistle functional and comfortable during regular use.

Suitable for

• Replacing a worn or damaged mouthpiece on compatible Fox40 single-pea or pealess whistles

How to use

To replace the jaw, remove the existing mouthpiece following the whistle manufacturer’s guidance and insert the silicone jaw until it seats securely in the mouth aperture. Ensure the jaw is correctly aligned and fully engaged so that it does not obstruct airflow or the pea/air chamber. Clean the silicone component before first use and after each period of heavy use using warm water and mild detergent, then rinse and air dry. Inspect the seating and material regularly and replace the jaw if it shows signs of tearing or excessive wear.

Usage recommendations

Use this silicone jaw as a direct replacement part for maintaining hygiene and comfort. Do not modify the piece or use solvents or abrasive cleaners. If the whistle’s acoustic performance changes after fitting the jaw, verify correct installation and consult official Fox40 guidance for compatible models.
