Bikes are getting smaller and there is limited space (especially on the liter bikes) so alot of riders are using their Nitrous bottles to spray and run the Air shifter but the problem is that it can shoot liquid Nitrous into the air valve. The Air valve freezes,this will convert the Liquid to a Gas before it gets to the air valve. Works on Nitrous,Nitrogen and Co2. This is not a Pressure regulator and will not regulator the pressure. It only converts Liquids to a Gas. Steel Braided lines and fittings are not included. Price is $65.00 shipped.
