RPB® Supplied Air Breathing Tube




The RPB® Breathing Air Tube supplies air from a flow control device, cool tube, heat tube, or C40 climate control device to the helmet.  RPB® Breathing Air tube was made for the Nova 1 and Nova 3 helmets.  This tube is also the replacement for NV2021 and should work with the Astro and Nova 2000.  These tubes come with the RPB helmets when you purchase them but may need replacement.
