7.9 Quad-Valve™ Exhaust Assembly

The Quad-Valve™ exhaust became standard on the Kirby Morgan 37 helmet as of March 2005. This is a superior exhaust system that ties together the regula- tor exhaust and the helmet exhaust into one unit with exceptionally low exhalation resistance.

The Quad-Valve™ is nearly identical in design to the previously standard Tri-Valve™. The difference between the two units is that the Quad-Valve™ uses the quad exhaust cover to connect the exhaust body to the exhaust main body. All other parts are identical. If you have an older KM37 helmet you are strongly encouraged to upgrade your helmet to the Quad- Valve™ design with the Quad Valve cover.
