The Uniweld RHP400 is the best nitrogen regulator for those who want a premium device. It is both precise and durable with an excellent build quality. The Uniweld is a brand name you can trust. It is a standard 0-400 PSI nitrogen regulator and can fit CO2 tanks with an adaptor.


If you have a grill or kegerator, chances are you will need the best nitrogen regulator. They essentially help reduce the highly pressurized gas or liquid from a tank to a usable form. Nitrogen regulators are also known as beer regulators. However, they are not just limited to be used at the bar or home. They can be used for all sorts of applications and industries. Air regulators are used from cooking to air compressors to delivering propane gas.

The best nitrogen regulator is a device that will efficiently control the flow of CO2 or nitrogen from the gas cylinder. Once you have dialed down the air pressure, you can deliver the new output to anything. One of the most popular commercial uses is to deliver CO2 from a highly pressurized air tank to syrup to make carbonated drinks.

A nitrogen regulator is usually composed of a cylinder value, a shut-off value, a pressure gauge, and a tube. The cylinder value is normally used to adjust the pressure of the gas coming in. The pressure gauge will accurately indicate the pressure of the gas going out. Sometimes there will be another gauge to measure the pressure of the air coming in. Some gauges will even tell you how much gas is left in your tank. Finally, there will usually also be a shut-off value to make sure there is some sort of quick emergency shut off.

There are different types of regulators available on the market. In general, you have primary and secondary regulators. There are also CO2 and Nitrogen regulators. And finally, you have single gauge and dual gauge regulators. We will go into detailed about these below in our buying guide section. Just know for now that a primary regulator is the most standard option available.

It is the preferred brand of many professionals and fortune 500 companies. This is because it has incredible durability and great performance. The trade off is that you tend to pay a premium for this.
If you want the best nitrogen regulator that is precise and durable, you should look at the Uniweld RHP400.

This is a standard 0-400 PSI gas regulator designed for nitrogen tanks. However, it can also be used with CO2 tanks with an adaptor. We like that this nitrogen regulator is simple to use and durable as a rock. Other nitrogen regulators we have tried always has some kind of little flaw. There could be a valve that gets stuck or a pressure gauge that malfunctions. Maybe the numbers are small and hard to read on the pressure gauge. Or the regulator does not fit any tanks. We are scratching our heads to find a flaw in the Uniweld RHP400.

In terms of build quality, the Uniweld RHP400 features a large brass tee handle with a stainless steel adjustment screw. This ensures a smooth and accurate delivery pressure adjustments. There is a self re-seating relief valve and a very durable brass piston designed diaphragm. For connection, you have a CGA580 inlet connection and a 1/5 inch male flare outlet connection.

Best Nitrogen Regulator Buying Guide

best nitrogen regulator

Most nitrogen regulators are generic pressure regulators that can deliver all sorts of liquids and gasses. It It will reduce the input pressure of a particular gas to a desired value and then deliver it out. If you don’t have a regulator, you would release all of the pressurized air at once and risk damaging something. These nitrogen regulators are particularly popular in dispensing beer and soft drinks. This is because you need a way to mix the carbonation with the drink.

Operating a nitrogen regulator can be intimidating, but you should easily get the hang of things. First, you need to hook up the regulator to your gas tank. Make sure the connection is extra tight to prevent leaking. Next, you should slowly turn on the gas, which is usually a valve on the regulator or the tank itself. There should be a pressure gauge indicating the pressure of the air coming in and the pressure of the air going out. Finally, you can turn a valve to regulate the outgoing pressure and open and close the output via a choke valve.

Trying to pick the best nitrogen regulator can be a total nightmare. There are many factors to consider and if you are new to the game, you will have to learn some terminology. You need to be aware of the type of nitrogen regulator you are getting. You should also know the type of regulator to get for what tank type. Some nitrogen regulators can fit both CO2 and nitrogen tanks, while others require separate regulators. For the most part, it is tough to interchange the two because nitrogen regulators are made to withstand higher pressures. Nevertheless, you should consider the following factors when shopping around: regulator type, performance, durability, and ease of use.

Regulator Type: In general, you have primary, secondary, and panel models. Primary regulators are your main workhorses. They are the most common option available and are directly connected to the gas tank. You primary regulator should always have some kind of shut off value for safety reasons. Primary regulators can have more than one input and more than one output.

Secondary regulators are an extension of primary nitrogen regulators. They are usually attached to primary regulators and further reduce the amount of pressure going out. They are used to fine tune the air pressure of the final product. Although secondary gas regulators are not entirely necessary, they are nice to have if you need variable air pressures.

Finally, you have panel regulators, which are large expensive regulators used in large coolers. It is an entire system usually with nice LCD displays. These panel regulators usually include one primary regulator and a bunch of secondary regulators.

Performance: The best way to gauge the performance of a nitrogen regulator is to measure the range of pressures that it regulates and delivers. More expensive regulators will be able to perform accurately without leaking at higher PSIs. This is not a commodity where everything has more or less the same price and quality. There is usually a wide range of options available for regulators with varying price tags. More expensive nitrogen regulators can usually withstand tremendous amounts of pressure coming in. They can also regulate extremely accurately over wider ranges.

Durability: If you want to get the best nitrogen regulator, be sure that it is durable. It should be able to withstand a beating and falls. There will be times when you need to apply pressure on the valves to open and close them. You may also be throwing the unit around a lot, especially if you use it for work. Finally, if you are regulating high amounts of pressure, you want a regulator that won’t burst or leak over time. It is also paramount to have accurate pressure gauges, especially if you need precision in your line of work. In general, find nitrogen regulators made of hard metals with sturdy handles. Brass bodies are usually quite durable.

Ease of Use: You should opt for a nitrogen regulator that is easy to install. They should fit most types of hoses and connection types. The best nitrogen regulators should also allow you to easily regulate the outgoing pressure. You shouldn’t have to use unnecessary force to twist and turn the valves. The readings on the gauges should be easy to read and always accurate
