What is a Pressure Washer Gun?
While it has the word “gun” in the name, a pressure washer gun is actually more like a trigger, than a fully fledged firing mechanism. A pressure washer gun represents the connection between the pressurized water and the item you are spraying. If you were to use your pressure washer (and this goes for both gas and electric version) without a pressure washer gun, you will have little to no flow control. This is the reason why some people call these pressure washer guns and others call these trigger guns.
Regardless of what you decide to call this piece of equipment, you need a trigger fun to control the flow or rather output of the pressurized water, or if you are using a foam cannon, you will be able to control the foam. The best way to describe a pressure washer fun is to go through each of the main parts.
Anatomy of Pressure Washer Spray Guns
Like all pieces of equipment a pressure washer gun has essential parts, these are usually made of durable and water-resistant metal which are in control of keeping the water in and also letting it out on command.
While there are many pressure guns on the market, they are all engineered with very minor differences and they are all operated around a trigger activated ball valve.
A spray gun is made up of:
- The outer plastic case
- The trigger mechanism/parts – Usually a simple lever connected to the hand trigger which controls the valve and the control pin. This is the part that you pressure while you grip the pressure washer gun.
- The control pin and valve – When you pull the trigger, it pushes the ball into the valve, allowing the water to flow through the nozzle, this is the end of the line pressurized water. When the trigger is in the idle position, i.e. you haven’t pressed it. The water is held back by the pin when you move the trigger, you release the pin and the valve opens up, allowing the water through.
- Spray Lance & extensions – You’ll find that some pressure washer guns include the extension lance as a part of the build. Sometimes this lance is stabilized with a very firm connection to the main body and the valve, if this is the case you can’t remove the lance.
You’ll find that the pressure washer industry has many terms to describe the same parts when it comes to spray guns, so it can be overly complicated.
These key parts of your trigger gun work together to control the flow of the pressurized water. Whether you want to let the pressurized water through or to stop it. On the face of it, this may not sound like an impressive thing, but if you take into account that we aren’t talking about a garden hose here, we are talking about controlling the massive amount of pressure that your pressure washer creates all in these small parts that fit into the palm of your hand.
Other features include the ergonomics which while this isn’t essential, some pressure washer guns just have a better handle that works better in you handle. Some have a body made of thick plastic.
This gear is made to be very durable.
Industry Names for Spray Gun Kits
It’s most accurate to call the part which holds the trigger, the spray gun, and the steel part with the nozzle tip the lance or wand.
Typically the spray gun, sometimes called a trigger gun, has a 1-foot plastic casing; this is where the steel tube is usually housed.
However, you may have a gun that is very similar but doesn’t have the 1-foot casing; this is often referred to as a trigger gun.
Now you have an understanding of the parts and names for guns, check out this video below, show the how spray guns come apart in this disassembling video.
How the Trigger Gun Works
The main parts of a spray trigger gun are the valve and the trigger interaction.
When the trigger is locked, I.e., you haven’t squeezed it, the ball inside the valve is sitting in place, being held there by a spring blocking the water from going through.
When you pull the trigger, the trigger rotates around on an axis and pushes down on the control pin. What this does, it effectively pushes the ball against the spring holding it in place, this moves the ball out of the way so that the water can flow through the valve to the spray nozzle.
When you release the trigger, the spring pushes the ball back onto its seat, blocking the water flow.
That’s not all that happens, in addition to the valve and trigger interaction, there’s also the interaction between the trigger gun ball and the unloader valve on your pressure washer pump.
When the pressure washer is turned on, but you haven’t pulled the trigger, it’s the job of the unloader valve is to divert the water from the pump back to the pump inlet so that the pressure doesn’t build too high. It knows to do this by sensing an increase in the pressure or a change in the water flow.
When you pull the trigger to pressure washer something, the unloader valve senses the pressure or flow changes (this depends on the type of the unloader valve) and stops diverting water flow through the pump.
Pressure Washer Gun Types
When looking at pressure washer gun types, you can make distinctions between them based on several different qualities. These criteria are combined into a wide range of pressure washer guns. Firstly we have the PSI and GPM ratings, water temperature, the additional gear. All of these are combined together in some way in each and every pressure washer gun.
1. PSI and GPM
Every single trigger on the market will have some sort of threshold when it comes to the amount of PSI (pounds per square inch) and GPM (gallons per minute) rating that they can handle. Some are designed to be compatible with smaller pressure washers, while otherrs have been made to withstand the huge pressures created by commercial pressure washers reaching 10+ GPM and over 5000 PSI.
- Residential spray gun – This type of trigger gun is designed for use with light to medium-duty power washers. These work perfectly with electric pressure washers which usually have a lower PSI and GPM rating. A residential spray gun will have a much lower PSI requirement and also a lower maximum PSI threshold. That said, almost all residential pressure washers work with residential trigger guns, though you can use commercial should you wish.
- Commercial pressure washer guns – which as the name suggests are designed to work with commercial pressure washers which means they need to withstand higher pressure ranges and much more frequent use. The PSI and GPM threshold is a lot higher than what a residential trigger gun can handle.
2. Water Temperature
It should come as no secret that hot water brings a lot of advantages to the table when it comes to cleaning. Just look at hot water pressure washers. If you use hot water often, then you’ll be pleased to know that there are trigger gun models that support hot water flow, so you don’t be stuck with the one that came with your pressure washer. Usually, when a gun supports hot water pressure washer, they will have a thicker body, or the grip will be made out of a heat-resistant material so you don’t end up burning your hands.
Every pressure washer gun should be capable of supporting up to 140° F though make sure to double-check the products specifications before your make your final decision. There are also pressure washer guns that can handle with ease heat ranges all the way up to 300° F and some can handle even hotter temperatures. These pressure washer guns will usually come with a higher price tag, but the payoff is worth it for though who use hot water often.
3. Pressure Washer Gun Kits
As I’m sure you are already aware, pressure washer guns are compatible with all sorts of extensions, including the very famous quick-connect nozzles. This additional gear is incredibly helpful for tackling different tasks, though problems do start to appear when you start to lose parts such as a nozzle tip. These nozzle tips are small and easily get lost, much easier than you think.. I’ve been told off a few times as my wife finds one in the washing machine. Also you need to be aware that some nozzles won’t be compatible with a new pressure washer gun.
If you’ve lost some or all of your old quick-connect nozzles or you are worried that they just won’t fit the new wand. Then you can purchase a pressure washer gun set, and use your pressure washer like it’s brand new. These sets usually include the following.
- The trigger gun which is capable of supporting the nozzle tips
- A set of quick connect nozzle tips – You’ll find the most commonly included is color-coded with each color corresponding to it’s spray angle. A standard set includes 0°,15°,25° or 30°, and a 45° nozzle. Anything more than this is a nice bonus.
- A spray lance or wand – if the trigger gun doesn’t come with an integrated wand already, these sets give you the option to extend your pressure washer gun.
Pressure Washer Buying Guide
Now that we’ve covered the basics about pressure washer guns. It’s time to look into the finer details, the details that you should keep in mind when you are looking for a trigger gun for your pressure washer. I really encourage you to use this knowledge and create a check-list of features that you want from your brand new pressure washer guns. There is no perfect model, but there will be one that meets most of your checklist. So here’s what you should consider before you purchase.
1. Quick Connect
The first feature that I look for in any new pressure washer gun is the connectors. You’ll find that couplers, valves and quick-connect connections are very common, but you should always double-check the connection type.
There are two types of connectors out there these fall into two sizes. 1/4 and 3/8 of an inch. These are standard and should match any high-pressure hose out there. However, some pressure washers do not come with a matching water intake quick connect. If you find yourself in this situation, you can either look for an adapter or find a model that fits.
Thankfully, the vast majority of pressure washer guns come with several adapters for the water intake connections. Though I suggest using some Teflon tape to secure the extension and the high-pressure hose.
2. Wand Length
Whether you decide to get a pressure washer gun that comes with a wand (also known as a lance) is up to you, or rather, the choice will depend on your washing habits. To put things into perspective, if you like to use foam cannons often then a 40″ extended pressure washer lance won’t do your any good, because the foam cannon also adds length. In this case, I suggest going for a pressure washer gun that has a short lance or even no lance at all. You can always attach an extension lance if you need, though these can be flimsy sometimes, it’s down to the material it’s made from.
If however, you aren’t someone who often uses foam cannons and prefers a strong and stable lance, then a longer and thicker wand will give you the ability to grip it with both hands, which results in better overall control. If the long wand is integrated into the trigger wand, you sacrifice versatility for stability because usually, this lance isn’t removable.
3. Hot or Cold Washing
Pressure washers come in all shapes and sizes to match the wide variety of different washing habits that people have. So before you make your final decision over what pressure washer gun you want to get as a replacement or even an upgrade, you have to take into consideration the temperature. Pressure washers that deal with hot water, are quite different from a cold-water pressure washer and thats thanks to the heating system.
Because of this a pressure washer gun not only has to be strong enough to withstand the pressure, but also the heat. If you like to apply some extra degrees or temperature for that additional cleaning power, you need to double check the temperature rating on your pressure washer gun. Every tigger gun out there can use cold-water, but there’s a select few which are designed to support hot water pressure washing. Make sure to check the gun models specs and compare them to the heat that your pressure washer will operate at.
If you happen to purchase a gun model that can’t support hot washing, don’t worry, you can still use it, but only on the cold-water only setting. Many have tried to use a non-hot-water pressure washer gun with hot water and everytime they fail, so make sure to double-check the heat rating and you’ll be all set.
4. PSI and GPM Rating
Ok, first things first, I need to set the story straight. If a pressure washer gun says that it’s a 4,000 PSI gun, that doesn’t mean that it needs or produces that kind of pressure. Instead that 4000 PSI rating tells you the maximum operating pressure that this gun has been designed to withstand. There’s the other side of the coin as well and that’s that minimum amount of pressure needed.
The minimum and maximum PSI (and in some cases the GPM) rating should match the rating of your pressure washer. For example, if your gun is used with pressures or up to 3,000 or even 4,000 PSI then using this gun with a strong pressure washer is a no go, the pressure washer will break the gun as these strong pressure washers are usually only 4000 PSI. You washers gun range must match or include the range of you washer, others you will experience trouble including damage.
By including the range what I mean is, if you pressure washer can work at 1800 PSI up to 2800 PSI, then you need a gun that can work those ranges too. But you don’t need a gun to match those ranges. So while a gun could have a range of 1800 PSI minimum to a 2800 PSI maximum, it could also have 800 PSI minimum and 4000 PSI maximum, that would still work for you as 1800-2800 PSI sits within 800-4000 PSI.
While these days pressure washer guns are made of durable materials, typically being brass, this doesn’t mean that you can use every gun with any washer, take a minute or two and compare the pressure ratings, I advocate safety first and this is will within the safety area and speaking of safety…
5. Safety Features
Pressure washer guns are actually really simple gadgets, but the technology behind them must be spot on for safe and sound operation. Due to their simple design, there isn’t much scope to stack up a raft of safety features into the small body of the trigger gun. But here’s a list of the most popular safety features that you’ll find on a pressure washer gun:
- The grip – As these trigger wands are dealing with massive amounts of pressure, some manufacturers have decided to put additional gripping materials onto the gunds handle. Usually this is a water-resistant rubber to ensure that you have a firm grip.
- The safety mechanism – Like a real gun, a pressure washer gun will usually have a safety locking mechanism as well. This is a great feature which makes sure that no one gets hurt while you’re in the middle of your spring clean up.
- Swiveling quick connectors – If you tend to move around while you clean and well who doesn’t? the high-pressure hose can easily get tangled, which is annoying and costs time, worse case you may find yourself short on hose due to the tangles, this may mean you spray in the wrong place… If your pressure washer gun has a rotating or swiveling connector, the chances of your hose getting tangled are drastically reduced.
Two Main Styles of Replacement Guns
There are two types of replacement spray gun which you can purchase.
- Full kits – These include the spray gun, the spray lance, the nozzle tips, connections, and sometimes even a high-pressure hose.
- Just the spray or trigger gun, this doesn’t include the extras such as the lance, nozzles or connections, you just get the gun.
The most common part to break on your spray/trigger gun is the trigger gun assembly part itself, so you may need to replace just that alone.
It may be easier to just buy the full kit, to remove any doubt about connections and fittings.
Who needs a pressure washer gun?
If you own or use a pressure washer gun often, you are going to need a new pressure gun at some point. Regardless of how strong your pressure washer gun is. Entropy will get to it eventually, or rather, wear and tear will win. You trigger gun is dealing with huge amounts of water under high pressures so it is going to fail at some point.
This is why I find it’s always best to keep a spare gun lying around. There are other reasons to buy a pressure washer gun even though the one you have may still work.
Due to how available these things are, and also based on their budget, it’s quite common for people to use multiple pressure washer guns on the same washer. The reason for this is down to shape and accessibility. Owners of versatile models (like commercial pressure washers) have the ability to utilize different settings and PSI ratings. These people also make sure to fit only pressure washer guns that fit their certain pressure ranges.
To make that a little bit more clear, when you deal with the lower pressure ranges, you might want to get a pressure washer gun that is shorter, this makes it easier to hold. Trust me, the helps a lot. The longer the gun the more strain your arms and hands get trying to keep hold of it and keep it elevated. Plus it’s easier to control the direct and direction with shorter pressure washer guns.
But as the pressure increases you’ll want to swap control with ease. Higher pressures, demand a firmer grip, or a model that features a firmer trigger. You want to pick one which suits your pressure washer needs and experience.
Are Replacement Guns Universal, or Do I Need the Same Brand as My Pressure Washer?
With the availability of threaded and quick-connect connection fittings, you can make any spray gun 100% universal. You don’t need to purchase a replacement or upgrade spray gun; that’s the same brand as your pressure washer.
Just note, that if it breaks within the warranty people, it’s an easy part for your manufacturer to replace.
What’s the Difference: Industrial Spray Gun vs. Residential Medium-duty?
Industrial spray guns are designed to work perfectly with the specifications of industrial power machines. Hot water capable power washers, high flow rate, and high pressures that the best gas pressure washers produce work perfectly well with industrial trigger guns, but can break the residential spray gun models, as these aren’t designed for the high specs.
Also, the higher specs of the industrial guns will cost more, as they are made with higher quality valves and material components
Typical Industrial Spray Gun Specs
You’ll see one of the most popular trigger guns on this list, it’s the Suttner St-2700 which is made with stainless steel components.

You might be surprised to know that you can use an industrial trigger gun with a residential electric pressure washer. I’ve upgraded my residential pressure washer with a trigger gun from a commercial-duty pressure washer if you are wondering, I own the Suttner St-2700 202700600.
FAQ About Pressure Washer Guns
1. What is the difference between a pressure washer lance, gun, trigger gun, and a wand?
This can be rather confusing, but all of those terms mean the same thing, with some minor differences. A pressure washer gun and trigger gun are basically the same. But on the other hand, a wand and a lance, which are usually used interchangeably to represent a standard pressure washer gun, actually have a small difference. A lance or wand is used when a pressure washer gun has an integrated longer output nozzle.
So the to long didn’t read (TLDR) – A pressure washer gun and trigger gun are the same, a lance or rather wand, can be used to represent a pressure washer gun which has an integrated longer nozzle.
2. How do I know if I need a new pressure washer gun?
If you have found this guide because you are looking to find a replacement for your current pressure washer gun, then i’ve got you covered. Early signs of a worn-out pressure washer gun can be somewhat difficult to spot, especially if you are a new user. But a quick inspection of you fun and you’ll know very quickly if it’s fault or not, so here’s a few tips.
- Leaking – If you find any leaks coming from the quick connector or the output. Leaking is never welcome because it reduces the performance of your pressure washer. If leaks occur, the engine (or motor) won’t be able to produce the PSI and GPM ratings because it’s losing pressure, and as such it’ll be more difficult to remove dirt.
- Drop-in performance – If you pressure washer pressure gauges (not featured on all pressure washers) start to show pressure drops, the source of the problem would well be a faulty pressure washer gun.
- The connectors fail – This is perhaps one of the most dangerous signs that something is wrong. This is where the gun randomly disconnects from the high-pressure hose. If something like this happens make sure to stop the washing session immediately and start looking for a replacement pressure washer gun and also a replacement pressure washer hose. That may seem a bit overkill, but a disconnect means that one or both of the connectors now have a fault, and the disconnect may have caused damage to both.
3. Can I use a pressure washer gun with hot water?
I’ve covers this subject in the sections above, but as this question is so common, I felt it made sense to clarify it again. The answer is is that it entirely depends on the pressure washer gun itself. Some trigger guns have been designed to operate with hot water and others only cold water. Every model that can withstand hot water can be used with cold water, but do remember that the opposite doesn’t apply, if a trigger wand is designed for cold-water use, then that’s all it’s designed for.
Make sure to check the specs of your trigger gun and see what it’s heat threshold is. A typical gun will be able to handle up to 140° F.
4. Do I need the pressure washer gun from the same manufacturer that made my pressure washer?
This may seems like the most logical thing to do, but in all honestly it’s not always the smartest choice. Pressure washers deal with dangerous levels of pressure, so the main thing that you should be absolutely certain about is the connectors. If they match between the hose and gun then you will have a secure connection. There are several standards when it comes to connectors but most guns will fit either a 3/8 or 1/4 inch connector.
There are a wide variety of pressure washer gun adapters and yours may include some, so remember to check that before you give up on a model just because it’s basic connector doesn’t fit.
5. Can I use my pressure washer without a pressure washer gun?
If your pressure washer gun has unfortunately failed or started slacking so you are getting leaks. Then you shouldn’t use it anymore. Now you may think that it makes sense to just use the pressure washer hose on it’s own while a replacement comes in. But please never do that! Pressurized water is no joke and it will cause serious injuries. A simple high-pressure hose is not enough to contain the pressure and certainly not enough to control it’s direction. This is why there are pressure washer guns.
