Pressure washer nozzle is an essential part of pressure washing. This tool makes it relatively easier for us to wash or clean any stain.
Today, I am going to elaborate on different types of pressure washer nozzles, their uses and in which situation they can be appropriately used.
Many types of pressure washer nozzles are used for different purposes. It varies in shapes, sizes, colors and spray angles. There are two basic kinds of nozzles, Threaded and quick connect. Threaded nozzles create a leak-proof seal between the nozzle and manifold and can be used with pressure washer accessories. Quick connect nozzles comes in different colors, each representing a different spray angle.
What are Pressure Washers
Pressure washing is the alternative method of manual cleaning of household objects. Pressure washers deliver a high-pressure flow of water to remove all kinds of dirt, dust, mold, paint, stains or any dark spots efficiently from our vehicles, housing objects, equipment or concrete surfaces. If you are interested in how a pressure washer works then you should read Explain that Stuff.
What are the Uses of Pressure Washers
Pressure washers can be used for any cleaning job efficiently. From rinsing your windows and cleaning mud on your vehicles, or removing any tough stain on concrete, pressure washers can handle all these situations given that you have the right type of nozzle for the necessary job.
What are Pressure Washer Nozzle
A pressure washer nozzle is a device or tool which is devised in such a way that when you attach it on the tip of a tube or pipe, it results in an enhanced and speedy flow of water or any other fluid.
It also helps in modifying direction, shape, mass or pressure of the stream depending upon which kind of washer nozzle is used.
How Does the Power Washer Nozzle Work
You must be wondering how does this little tool exert such a high force pressure? Well, the mechanism of this device is pretty simple.
Let me explain with a primary example. When you are watering your plants in the garden with a simple hosepipe or garden hose and the flow of water is quite low.
What do you do to increase it?
You merely cover some part of the tip of the hose with your thumb so that the water can be exerted from the remaining portion with higher pressure.
Similarly, when you attach a nozzle to the pressure washer, it limits the flow of the fluid according to the shape of the The nozzle and exerts it with constant pressure and greater distance.
Matching the Right Nozzle for the Intended Purpose
Appropriate nozzle size is very critical for proper function of your pressure washer. A wide range of power washer tips is available for each purpose. For effective use, it is recommended to use the exact size of the nozzle which is required.
Larger size than required will decrease the efficiency of the power cleaning by eroding the water force which will drain the water quickly while a smaller than needed nozzle will damage the pressure washer device as it will place the water force back into the system through the water hose.
Types of Pressure Washer Nozzles – A Brief
Illustration by: Consumer Reports
There are numerous types of pressure washer nozzles, each serving a different purpose. As it was described earlier, two primary types are threaded and quick connect which have several sub-types. Let us have a brief overview of these types.
- Red: A red nozzle is known for the strongest flow of water. It has a 0-degree angle. It is used to remove heavy stains of mud or dirt form construction, tar, or glue.
- Yellow: The yellow nozzle has a 15-degree angle and is typically used to wash concrete or tiles in the buildings.
- Green: A green nozzle has a 25-degree spray, and it is best used for washing household objects. If you want to wash any of your vehicles or dust from your furniture or wood decks, this tip is recommended.
- White: A white nozzle produces a 40-degree angle spray. It is also known to be user-friendly as it offers a slightly wider angle as compared to the previous tips and is best suitable for washing windows or siding.
- Black: A Blacktip procures a 65-degree spray and is known to have to the lightest flow. It exerts a very gentle pressure and is used to make surfaces wet.
Let us now get into details for each nozzle individually.
Types of Pressure Washer Nozzles – Explained
1. Red Nozzle
Red tip nozzle is known to be quite dangerous as it throws a mighty water stream and can create a lot of damage, so you have to be careful while using it. It covers smaller areas with full force.
It exerts maximum blast and used when you have to clean stubborn stains. Using it on soft objects or closer to any surface is not recommended as it can damage the surface or object. It also shouldn’t be used on humans or animals. Some of its best uses are:
- To clean overhead areas
- To clean debris from concrete
- To clean rust from steel or aluminum
- To remove mud or dirt from construction
2. Yellow Nozzle
Yellow tip nozzles have a 15-degree angle and produce more significant throw than red nozzles. This nozzle is best recommended when you have to remove rust and greases from surfaces or peel off old paints.
You can clean any stubborn stains of dirt with this tip, from a reasonable distance. It is mostly used:
- To clean mud and dust
- To remove strong mildew stains
- To remove smears or greasy substances
- To remove loose paint from metal or woods
3. Green Nozzle
A green tip offers a 25-degree angle and is probably the most used power washer tip. It is the most common nozzle used in homes. This nozzle covers a wide area and is used for a variety of common washing causes. It is best used for cleaning muddy areas. Some of its popular uses are:
- To remove pale fungi stains
- To clean gutters and downspouts
- To clean patio furniture or boats
- To clean filthy and polluted areas
- To clear leaves from driveways or sidewalks.
4. White Nozzle
A 40-degree nozzle is color-coded white and generates an extensive spray pattern. It exerts a very low pressure and is ideal for washing soft or sensitive surfaces like windows, glasses or thin wood. The white tip is a very gentle and user-friendly nozzle. Its common uses are:
- To clean rooftops
- To clean windows and blinds
- To clean and wash automobiles
- To wash lighter and sensitive objects
5. Black Nozzle
A blacktip offers the lightest flow of water with a quite wider 60-degree angle. This nozzle is often used with soaps and detergents. It is recommended for use when a small amount of water force is required as the wider angle limits the water force of the nozzle. It is a low-pressure nozzle and comes with a large orifice as well. It is best used with detergents to clean objects.
6. Turbo/Rotary Nozzle
This nozzle is a combination of red and green tip nozzles and is also known as rotating washer nozzle. It emits water with a direct force on the surface but also rotates with a 25-degree angle.
It generates a circular cone shape and is a good alternative for 0-degree nozzle as it emits with the same force but with a broader spray area.
7. Chemical nozzle
A chemical nozzle is used when a chemical has to be mixed with water. A chemical nozzle is available in both threaded and quick connect systems.
As compared to other nozzles, the chemical nozzle has a quite bigger orifice as they are essential in reducing the water flow. The angle of this nozzle is also broader so that the cleaning chemical is mixed correctly.
8. Adjustable/Variable Nozzle
A variable nozzle is an All-in-one nozzle. It is adjustable and allows the users to adjust quickly with the necessary environment. You can rotate the angle to your intended purpose. It is quite easy to use with a simple twist of the nozzle and is utilized for multi purposes.
If you want to make you cleaning even more efficient and effective, you can try some of popular pressure washer attachments such as:
- Rotary nozzle
- Expandable wand
- Surface cleaner
- Pressure washing broom
- Soap/detergent reservoir

12 Frequently Asked Questions About Pressure Washer Nozzles (FAQs)
Question 1: What is PSI and GPM, and why are they important?
Answer: PSI stands for pounds per square inch. It measures the flow of water emitting from the pressure washer.
GPM stands for gallons per minute, It tells us the quantity of water flowing through the power washer.
They are both important because they provide the cleaning power of the pressure washer.
Question 2: How do I know which nozzle to use?
Answer: Each nozzle type is intended for a different purpose and explicitly designed for that. They have different spray patterns as well. Start with a lower pressure nozzle first and test it on a smaller area. Nozzles with higher pressure can damage soft surfaces.
Question 3: How far from the cleaning surface, should the nozzle be held?
Answer: If the surface you are cleaning is a sensitive or soft one, you should hold the nozzle around 3 to 5 feet from the surface. If you are cleaning hard surfaces, then around 6 inches from the surface would be sufficient.
Question 4: Why are there different colored nozzles?
Answer: Different colors of nozzles represent different purposes.
- Red – 0° Nozzle: It provides very precise, concentrated stream – It cleans limited area at a time
- Yellow – 15° Nozzle: It supplies less concentrated stream – used for surface preparation
- Green – 25° Nozzle: It delivers a broad stream – it is best for removing dirt and mud
- White – 40º Nozzle: It provides the most extensive stream – it is best for wood restoration
- Black – Low-Pressure Nozzle: It has a very broad stream – it is mainly used with detergents
Question 5: What if there is low pressure?
Answer: The most obvious cause of low pressure is when you have a wrong nozzle attached to the washer or if the nozzle is worn out. Make sure that the water is coming properly to the equipment or not.
Question 6: What to do when water is not coming from the pressure nozzle?
Answer: The first thing to do when the water doesn’t spray from the washer is to check the pressure nozzle. Sometimes different substances or chemicals can clog the nozzle. You can simply clean the nozzle properly, and that should resolve the issue.
Question 7: The Nozzle is clean, but water still not coming out, why?
Answer: If the nozzle is clean, check the inlet screen. If it’s clean too, then see if you can hear a sucking sound. That is the pump sucking air caused by a loose clamp or a dry detergent container. Refill the detergent container and replace the loose clamp to resolve the issues.
Question 8: Chemical/detergent injector is not working
Answer: You might be using the wrong nozzle, the soap tube inlet filter might be clogged, or the detergent mixture could be too thick. Resolve these problems by inserting the black tip nozzle, flush the soap filter with fresh water and add more water to dilute the detergent mixture.
Question 9: How to Clear the Nozzle Tip?
Answer: Always use a needle to clear the nozzle tip of any debris. Anything blocking the tip of the nozzle will cause a decrease in the flow and increase in the pressure in systems.
Question 10: What is the most important thing about nozzle in a pressure washer?
Answer: The most important thing about the nozzle is that it creates the pressure. Without any nozzle, the washer won’t be able to generate any pressure and only inlet water pressure will flow through the spray gun.
Question 11: Is there a top reason why a nozzle might fail?
Answer: The simple flat tip nozzles don’t fail much. They deteriorate with time, causing a loss of pressure and efficiency. Clogging is also a big issue for nozzles. While the rotary nozzles could fail if the tip cracks or the turbine is damaged.
Question 12: How should nozzles be maintained?
Answer: Clean them properly from time to time to keep them in a neat state. After using detergents or any other substance, use a needle to clear the space.
