Since the Zeagle Razor is both a Regulator and a Valve, a means has to be provided to fill the cylinder that the Razor is screwed into.
Most Razors come with a filling adapter that provides either a connection point for a standard Scuba Valve Filling Whip or a connection to a standard tank valve.
A cap is unscrewed from the Filling Probe on the Razor and the filling adapter is connected in its place. The Razor comes equipped with a Burst Disc rated at 3000 PSI working pressure.
