Nitrogen Regulators

Finding a good regulator for nitrogen requires you to know what the regulator is supposed to do and how pressure in the lines is reflected in the gauge or gauges. Regulators come with different types of pressurization, and the threads should match the type of line you are running as well as ensure the design for the gas you need to flow through them.

What to Look for in a Nitrogen Regulator

Knowing what to look for in a nitrogen regulator means to know how one works. Knowing how a regulator works is the first step to knowing what you are looking for.

1Loading Mechanism

The loading mechanism is what helps delivery pressure to your nitrogen tank. The loading mechanism is a spring-loaded valve that has a hand knob. When you turn the knob, the spring is either compressed or released, and the nitrogen gas either flows or is restricted. When you compress the spring, the sensing element and controlling element comes into play to relieve pressure or restrict it.

2Sensing Element

The sensing element is an internal level that when the loading mechanism is compressed or released, it moves. The spring places pressure on the sensor with the element pressed into with the loading mechanism or into the control element depending on what you whether you are releasing or containing nitrogen.

3Control Element

The control element is the valve that opens and closes on with the use of the loading mechanism and the sensing element. The sensing element allows the pressure to change to allow the valve, the control element, to open and let the nitrogen flow. The seal it maintains is released, and the more pressure that is released, the greater the opening is, and the more pressurized gas can flow.


The diaphragm is the piece that presses the valve open or close. The diaphragm helps keep the flow of the nitrogen smooth and helps prevent the nitrogen from “off-gassing,” which will contaminate nitrogen. The diaphragm helps to absorb the contaminates and prevents tanks, tubes, and air from becoming contaminated.

What are the Bets Nitrogen Regulators?

The best regulators can have multiple parts and components to ensure the smooth functioning of the regulator and keep you safe. The best regulators from nitrogen and other gasses contain a control valve, a diaphragm, and a sensing element to ensure safe operation.

1Flame Technologies HPPR-IN-700-580 High-Pressure Piston Regulator

The Flame Technologies HPPR-IN-700-580 High-Pressure Piston Regulator is for nitrogen and argon gasses. The design of the regulator comes with a balanced stabilized control system with a moving piston component. The regulator is forged brass in the body and the bonnet control function.

The High-Pressure Piston has metal inlets that filter and contaminates and trap the impurities in the air and any that can contaminate the lines. The pressure regulators have two easy-to-read gauges that are 2 ½ inches wide that read the pressure flowing through the lines as they operate.

The gauges have a maximum pressure of seven hundred PSI that can handle up to 3.8 pounds of gas. The maximum Cyl pressure is four thousand PSI. The gauges are two inches in diameter, which makes them easy to read, and they come with ¼ an inch wide hose. The fittings can work with adaptors for different sizes of hose and tanks.


  • The Flame Technologies regulator works well for high-pressure regulation.
  • The regulator contains solid brass, which will not deteriorate with nitrogen or argon gases.
  • The regulator can regulate two different gases.


  • Flame Technologies regulator is hard to connect to some lines.
  • The regulator is very tight and hard to control.

2Uniweld RHP400 Nitrogen Regulator

The Uniweld RHP400 Nitrogen Regulator provides the user with up to four hundred PSI in pressure. It comes with a ¼ an inch male flare connection with two gauges that are easy to read. They have protective rubber gauge boots to lock the gauges onto the regulator safely.

The regulator contains brass with a strong diaphragm set to reseal the tank when turned off tightly. The brass gauge has a tee handle, also made with brass, is coupled to stainless steel screws that pressurize as you adjust the regulator. They also help to prevent galling from occurring.

The regulator can manage different types of gasses, including CO2, through the Uniweld piece as it has an F36 adaptor. The regulator is also set up to manage nitrogen as well as the CO2 cylinders. The gauges for both are easy to read at two inches wide with accurate pressure readings that adjust on as the amount of pressure goes up and down.


  • The Uniweld Nitrogen regulators have molded rubber to ensure a tight seal.
  • The regulator is solid brass preventing leaks or deterioration.
  • The regulator helps to control the flow from low to high.


  • The regulator metals can stick when attached.
  • The regulator can leak if not tight enough.

3Specialty Gas Regulator

The Specialty Gas Regulator measures pressure from fifty PSI to eight hundred PSI. The regulator is a dual regular allowing it to measure the pressure on two different gauges. The gauges are set to measure nitrogen through a ¼ inch male flare that connects to the line running to the gas with two-inch gauges for each.

The gauges are durable brass with rubber boots at the base of the gauges to ensure a tight fit for the tanks. They also have a brass diaphragm to help regulate the amount of gas flow through the lines as you use them.

The gauges sit on a tee handle that is pure brass. The handle connects to a stainless steel pressurized screw that helps to adjust the amount of pressure the gauges are receiving. The brush of the regulator will help to prevent galling.

The Specialty regulator can connect to a CO2 regulator using the F36 adaptor. It also connects with the nitrogen regulator to ensure proper control and safety of that gas. The regulator is lightweight at 2.5 pounds with simple, easy-to-use threads that make for a tight fit.


  • The gauges are pure brass with a control handle to switch between tanks.
  • The Specialty gas regulator comes with a tee handle to regulate multiple tanks.
  • The gauges can regulator CO2 as well as nitrogen.


  • The connecting tanks need to have the right threads for a safe hookup.
  • The stainless steel can react to other metals.

4Double Gauge Nitrogen Regulator

The Double Gauge Nitrogen Regulator regulates the pressure coming into the tank and out of it. The two gauges measure the pressure buildup for nitrogen that can switch between the two gauges with a red control handle. A second control handle helps to switch between a brass hookup and a stainless steel hookup.

The gauges measure the high pressure of trapped gas and low pressure for monitoring the pressure of the gas release. They both prevent the backflow of gas back into the main lines. The regular has a 5/16th barb and brass nipple to prevent leaks and for a tight connection.


  • The threads of the regulator are tight.
  • The Double Gauge Nitrogen Regulator is two thousand PSI.
  • The double gauges help to keep the keg tank functioning correctly.


  • The shutoff valves can break.
  • The gauge is only for a beer keg.

Final Thoughts

Knowing what to look for in a regulator means understanding pressure and how much to use for each type of tank. Not all gases can work with the same regulator, and not all regulators come ready-to-use. The best gauge is the one that will work for your needs.

Of all the gauges, the Specialty Gas Regulator provides you with the most flexibility for use. It allows you to manage up to eight hundred PSI of pressure. The gauge is pure brass, and the rubber boots each gauge has ensured the gauges stay tight while in use.
