This quick adapter combines the in & out valves in the FMJ05 gas mask into a single port for use with various rebreather systems.

The kit includes:
  • 2 way valveless converter for voice diaphragm - to connect to 40mm (NATO) accessories.
  • 40mm plug - for blocking existing inhale port

Remove the voice diaphragm and connect the converter so you can attach the rebreath bag to it. Block the small inhale port with the plug. You can now collect the exhaled air and partially reuse it by inhaling it again. A hot way of recycling the air.
