LifeGuard Disposable Mouthpiece

Disposable (slip-on) mouthpieces are for one time use. These mouthpieces are for one-time testing using a fresh disposable (slip-on) mouthpiece each time. Each mouthpiece comes individually factory sealed until the moment you need it. Slip one over the permanent (fold-away) mouthpiece and you’re ready to blow.
