RB160/RBSM - Rebreather Mouthpiece (DSV or Dive/Surface Valve) with RB Safety Mouthpiece Headstrap

The RB160 is our new and improved Rebreather Mouthpiece with true single-handed lever operation allowing you to switch easily between open and closed. The open position is for normal breathing from the rebreather and the closed position is used to seal the breathing loop, preventing water ingress and buoyancy loss, when removing the mouthpiece.

Key Features:

• True one-handed operation with prominent, easy-to-find raised grips which allow solid leverage between your thumb and fore-finger when moving the lever.
• Operational with either hand.
• Tactile feedback when switching - you can feel (& hear) the positive end-stop when in the fully open or fully closed positions.
• The mouthpiece outlet is offset to the top which lowers the mouthpiece body, increasing the diver's field-of-view and allowing easier access to a camera viewport.
• Sits comfortably in the mouth and is fully compatible with the AP RBSM Heads trap which further increases comfort and security.
• 15% improvement in work-of-breathing compared to the previous mouthpiece design.
• The position of the operating lever is visible to the buddy diver / instructor / dive supervisor.
• Improved design with in-built one-way silicone valves reduces the CO2 dead space in the chamber.
• Easy Clearing - the size of the water channel has been optimized to allow easy clearing when opening the valve.
• Deep ty-rap channel for secure mouthpiece attachment.
• Robust injection molded construction with strengthening ribs.
• Molded in Acetal with PTFE compounded in. The PTFE provides a degree of self-lubrication.
