The Pro Series Regulator Kit features the nitrogen (N2) and CO2 compatible XP300 SuperFlow Regulator. To be used on your own N2 or CO2 bottle. With a max outlet pressure of 330 PSI and an amazing 45 cfm, this regulator is the only one you need to pressurize your N2 shocks as well as run your air tools and inflate your tires with the awesome volume of CO2. Note: To fit to an N2 tank valve you will have to either use an N2 nut/nipple assembly (#UPG-6070) or buy the N2 to CO2 adapter (#FIT-0002). Don't buy an N2 regulator that is not designed to withstand the harsh temperatures of CO2. We're so confident in our SuperFlow Regulators that we back them with a limited lifetime warranty. This kit comes with the indestructible Power Grip guard for safety and our SuperFlex braided 25' high pressure hose rated for Power Tank pressures and temperatures. Limited lifetime Warranty on the regulator and guard and a 2 yr. on hose.
