Designed with true single-handed lever operation with easy-to-find raised grips (either hand), which is also visible to a dive buddy, the new and improved RB160 Rebreather Mouthpiece allows you to switch easily between open and closed positions.

Features include tactile feedback when switching; increased field-of-view and easier camera viewport access with a mouthpiece outlet offset to the top; comfortable and secure position in the mouth; full compatibility with AP REBSM Headstrap; easy clearing, with optimization of the water channel size; deep ty-rap channel for secure mouthpiece attachment; and robust injection-molded construction of Acetal with PTFE, with strengthening ribs.

It has a 15% improvement in work-of-breathing over its previous design and in-built one-way silicone valves, which lower CO₂ dead space in the chamber.
