SeaCure Custom Replacement Mouthpieces

The SeaCure X-Type Replacement Mouthpiece can be heat-molded around the individual diver's bite for a stable, low-effort fit. Its compact X-shaped profile reduces excess material in the mouth, while the custom impression helps distribute pressure more evenly than a standard one-shape mouthpiece.

Five connection sizes fit a broad range of regulator second stages without changing the molded bite-tab geometry. The included bite-limiting plug helps prevent over-closing during molding and doubles as a protective plug when the regulator is stored.
