Power Tank Super Flow XP400 Pro Series CO2 Regulator Kit

The Power Tank Super Flow XP400 Pro Series CO2 Regulator Kit is a complete high-output regulator system for off-road and overlanding use, delivering 48 cfm at a maximum outlet pressure of 400 psi. The kit includes the XP400 regulator, Power Grip Guard Handle, and a choice of Super Flex Hose in three configurations: 30 ft coiled, 30 ft DuroBraid straight, or 10 ft coiled.

48 cfm Flow Rate Built for Extreme Duty

The XP400 regulator delivers 48 cfm at up to 400 psi of outlet pressure. That flow rate is designed to inflate large off-road tires quickly, reseat beadlock or tubeless tires instantly, and run pneumatic air tools at full power in the field. That output level means less time airing up between stages or after a trail run, and enough pressure headroom to tune and charge nitrogen shocks without a separate shop compressor.

Freeze-Clog-Resistant Design

Power Tank Super Flow regulators are engineered to resist freeze clogging, a common failure mode in CO2 regulators under sustained high-flow use. For an overlander or off-road racer drawing heavily on a CO2 tank in cold conditions or back-to-back tire fills, a regulator that stays open and flowing is the difference between finishing the job and waiting for the valve to thaw.

Dual-Gas Compatibility and Tank Exchange Flexibility

The XP400 is a dual-gas regulator: it works with both CO2 and nitrogen (N2). CO2 use requires no adapter: the regulator threads directly onto US-manufactured CO2 bottles in 5, 10, 15, and 20 lb sizes. For N2 use, a separate adapter (Power Tank FIT-0002, sold separately) connects the regulator to a nitrogen tank valve. The kit is also suited to a tank-exchange workflow: install the Power Grip Guard and regulator on a rented CO2 tank, use it until empty, and exchange the empty bottle for a filled one without replacing the regulator.

Features

• 48 cfm flow rate: maximum outlet pressure of 400 psi for tire inflation, bead seating, air tools, and N2 shock charging
• Freeze-clog-resistant regulator: engineered to maintain flow under sustained high-output CO2 use
• Dual-gas rated: compatible with CO2 and N2 (nitrogen adapter FIT-0002 sold separately)
• Power Grip Guard Handle included: fits CO2 bottle neck diameters of 1-5/8" and 2-3/8"
• Three hose options: 30 ft coiled, 30 ft DuroBraid straight, or 10 ft coiled Super Flex Hose
• Limited lifetime warranty on the regulator and Power Grip Guard Handle; 2-year warranty on the hose

Specifications

Who This Is For and Isn't

The XP400 Regulator Kit suits off-road racers, overlanders, and serious trail users who need high-volume CO2 output for rapid tire inflation, bead seating, air tool operation, or nitrogen shock charging in the field. The XP400 fits US-manufactured CO2 bottles in 5, 10, 15, or 20 lb sizes with a 1-5/8" or 2-3/8" neck diameter, and works equally with owned or rented/exchanged tanks.

The XP400 does not fit Catalina CO2 bottles with a 2.6" neck diameter. N2 (nitrogen) use requires the separate Power Tank FIT-0002 adapter, which is not included in this kit. The Super Coupler is also sold separately and is not part of this kit. Using the regulator without the included Power Grip Guard Handle voids the warranty.

Common Questions

What CO2 tank sizes does the XP400 regulator fit?

The Power Tank XP400 regulator threads onto US-manufactured CO2 bottles in 5, 10, 15, and 20 lb sizes. The included Power Grip Guard Handle fits bottle neck diameters of 1-5/8" and 2-3/8", which are the diameters found on Luxfer and Thunderbird bottles. Catalina bottles with a 2.6" neck diameter are not compatible.

Can the XP400 be used with nitrogen instead of CO2?

The XP400 is a dual-gas regulator rated for both CO2 and nitrogen (N2). Connecting it to a nitrogen tank requires the Power Tank FIT-0002 adapter, which is sold separately and is not included in this kit. No adapter is needed for CO2 use.

Which hose option should I choose?

The XP400 Regulator Kit is available with three Super Flex Hose configurations: a 30 ft coiled hose, a 30 ft DuroBraid straight hose, or a 10 ft coiled hose. The 30 ft options give more reach around a vehicle for airing up all four tires without moving the tank; the 10 ft coiled hose is more compact for tighter storage.

Is the Super Coupler included in this kit?

The Super Coupler is not included in the XP400 Regulator Kit and is sold separately. The Super Coupler provides a universal fit for four plug types and a built-in pressure shut-off for switching between air tools with pressure in the hose.

What warranty does the XP400 Regulator Kit carry?

The XP400 regulator and the Power Grip Guard Handle each carry a limited lifetime warranty. The Super Flex Hose carries a 2-year warranty. The warranty on the regulator is void if the Power Grip Guard Handle is not properly fitted and used, which is why the regulator is only sold with the Power Grip Guard included.
