What does nozzle size mean? The orifice size of the nozzle determines the operating pressure of your machine. As a rule of thumb, the smaller the orifice, the greater the restriction of water flowing through the machine.
How to determine nozzle size?
Nozzle Size Calculator. Using the calculator below, enter your rated gpm and psi of your pressure washer. Once the "Nozzle Size" has populated, round to the nearest available size. Example, 2.58 would round to the nearest half size we offer, which is 2.5. Let’s say the calculator says you're in between sizes, and the "Nozzle Size" is 2.79.
What size nozzles should I choose for my misting system?
misting nozzles are designed to create a spray that angles out anywhere from 40° - 100°, depending on your system's water pressure. The wider the angle, the more area the spray will cover and the fewer nozzles will be needed. 18, 24 or 30 inch nozzle spacing is standard, but some suppliers will customize spacing to your needs.
What should be a spray gun nozzle size?
They’ve thoroughly tested their products and identified the best needle nozzle combination for each product. A general rule of thumb is: Heavy-bodied primers and primer surfacers work best when you use a nozzle size of 1.7 to 2.2. Basecoats should be sprayed with a 1.4 to 1.6 nozzle. Clearcoats should be sprayed with a 1.3 to 1.7 nozzle.
What is the diameter of the nozzle?
Nozzle diameter (plastic protrusion that the rubber tip slides onto)=6.5mm. Nozzle Depth (tip to base of nozzle)=5.5mm. There is a small indentation that helps keep the rubber tips on: It starts 1mm from the tip of the nozzle and ends 2.5mm from the tip of the nozzle. Indentation width is then= 1.5mm.
What is a nozzle size?
Nozzles are manufactured specifically for each machine's volume and pressure. This means that each nozzle size has a different size orifice (or opening). There are a variety of sizes but the most commonly used are between 3.0 to 6.5, sized in . 5 increments.
How do I know what size pressure washer nozzle I need?
Each pressure washer should have a specific nozzle size that comes with it.Find the PSI in top column.Move down the column until you find the GPM.The orifice size will be the number in the left column of the table.
How do you read a nozzle size?
In all cases the first two digits of the nozzle number indicate the spray angle (disperse) in degrees. EXAMPLE: 00 is 0 degree, 15 is 15 degree, 25 is 25 degree and 40 is 40 degree. The last two digits of the nozzle number indicate the orifice size, a standard industry designation.
What do nozzle numbers mean?
Most companies identify their flat-fan nozzles with a four or five digit number (Figure 2). The first numbers are the spray angle and the other numbers signify the discharge rate at rated pressure. For example, an 8005 has an 80 degree spray angle and will apply 0.5 gallons per minute (GPM) at rated pressure of 40 psi.
How do I choose the right nozzle?
You'll want to determine the nozzle flow rate at gallons per minute (gpm). To find that, start with your application rate in gallons per acre (gpa). Next, find an efficient and safe ground speed in miles per hour (mph). Then, determine the spray width per nozzle (W).
How do I choose a spray nozzle?
The best method for choosing the correct nozzle tip size is to determine the gallons per minute (GPM) of nozzle output required and then select a nozzle tip size that, when operated within the recommended pressure range, will provide this flow rate.
What is the most powerful pressure washer nozzle?
Red Spray TipRed Spray Tip (0-Degrees) The red spray tip creates a 0-degree spray pattern and is the most powerful nozzle of them all. You need to be very careful using this tip to make sure you don't cause any damage to the surface you are cleaning.
How do you measure a spray nozzle?
Steps to select the proper nozzle size:For broadcast applications, W = nozzle spacing (distance between two nozzles on the boom) in inches.For band spraying, W = band width in inches.For directed spraying, W = row spacing in inches (or band width) divided by the number of nozzles per row (or band).
What do teejet nozzle numbers mean?
These numbers refer to the flow rate in US gallons at the rated pressure of 40 PSI (approx. 3 BAR). For example, an 02 Nozzle is rated at 0.2 US gallons per hour at a pressure of 40 PSI.

What do colors of spray nozzles mean?
The first color scheme, the color of the spray nozzle tip, describes the capacity (flow rate) of the nozzle orifice at 40 PSI and is based on Standard 10625 of the International Standards Organization (ISO) (Table 1). Nozzle flow rates are mainly a function of orifice size & pressure.
Are pressure washer attachments universal?
The quick answer is no, they are not universal. The reason for this is that wands built for electric machines are made of different materials than those built for gas pressure washers. As well as, the fittings and connectors can be different and will need to be matched up to your machine.

What is the purpose of a fuel injector nozzle?
The nozzle’s main function is to spray the fuel in the cylinder in an atomized state (a mist) so it can be easily ignited to burn and therefore run the engine to the best of its potential.
Is a truck nozzle one size fits all?
However, the sacrifice is that although you are making more power, the truck will naturally run hotter and smokier, so it will not be as tow friendly or as ideal for daily driving. As you can see, there is some give and take with any nozzle size you choose and there is no “one size fits all”.
Is 30% injector nozzle good?
The 30% injector nozzle is very versatile, and that is why it is our most popular.
What is the most common nozzle size?
This means that each nozzle size has a different size orifice (or opening). There are a variety of sizes but the most commonly used are between 3.0 to 6.5, sized in .5 increments.
Why use a larger nozzle?
A common practice is to use a larger nozzle which will reduce the amount of pressure to ensure operators do not damage the cleaning surface. However, when a nozzle is larger than specified for the machine it will not produce the amount of pressure the machine is rated for.
What is the size of a fan nozzle?
There are a variety of sizes but the most commonly used are between 3.0 to 6.5, sized in .5 increments. All nozzles are stamped with a 5 digit number which identifies both the fan degree and nozzle size. For example, a nozzle with the number 40055 has a 40 degree fan pattern and is 5.5 in size.
What happens when a nozzle is smaller than specified?
When a nozzle is smaller than specified for the machine the effects vary depending on if it is a gas engine or electric motor. The added pressure caused by the resistance of pushing water through a smaller orifice will overload an engine and cause premature wear and tear.
What is the biggest misconception about pressure washing?
Are you damaging your pressure washing system by using the wrong nozzles? The most overlooked part of pressure washing systems is the nozzle. The common misconception is that nozzles are interchangeable on any machine.
What is a black nozzle?
The black nozzle is used for applying soap at low pressure and is sometimes used for low pressure rinsing.
What can alter the size of a nozzle?
Smart Maintenance Tip: There are many factors that can alter the size of a nozzle including hard water, debris, erosion, operator misuse, or blockage and therefore they should be visually inspected often and replaced periodically.
How far away should a nozzle be from a nozzle?
The force of the spray on a surface demonstrates this. Rarely is a nozzle held right up to the surface. Doing so can damage many surfaces. Generally a range of distance between four and ten inches seems to be the practical washing zone. A distance of over ten inches away from the surface generally is used for rinsing because at this distance the spray has very little impact. The most important factor governing how far from the surface the nozzle should be is the lack of damage to the surface combined with the cleaning result. On some wash jobs, a good example is house siding, you want to be a good cleaning distance, and at the same distance have the fan pattern hit on the top and the bottom of the clapboard. Depending on the distance required to obtain the desired cleaning result, the degree of fan can be changed so it impacts the area you desire.
Why is a nozzle chart necessary?
Because of these facts, the nozzle chart becomes necessary. Using different nozzle orifice sizes to change pressure is better than adjusting the unloader valve. When the unloader valve is adjusted to lower the pressure the gallon per minute flow is also reduced. The flow is very important when working.
Why does a spray nozzle have a small hole?
The restriction created at the nozzle is what causes the pressure to develop. If the spray nozzle hole size is so small that the pump can’t force the water through it at the pumps rated pressure, then the water flowing from the nozzle is reduced.
What is the larger area to the right of the nozzle size and below the PSI range?
The larger area to the right of the nozzle size and below the PSI range is the Gallons Per mMinute.
What is the color of a fan spray nozzle?
Most have a color-coding system that allows for easy fan spray identification. Red is zero, yellow is 15, green is 25, and white is 40. These nozzles must be connected into a quick connect coupler to use. When changing these nozzles it is very important to make sure the coupler locks down properly onto the nozzle plug. A habit of aiming the nozzle away from surfaces when first spraying is also a good idea. An improperly installed quick connect nozzle can be propelled out of the coupler and it can cause damage or injury.
What size nozzle does a TS2021 use?
We know the TS2021 is a 5.6 GPM pump so, under the 3500 PSI, scroll down until you see 5.61. Now scroll over to the left from the 5.61 to the Size column on the left had side and you will see that the TS2021 pump uses a #6 nozzle.
What is the fan pattern for a spray nozzle?
Spray nozzles are manufactured with various fan spray patterns. The most commonly used fan patterns are 0, 15, 25, 40, and 65 degrees. The higher the number of the fan, the wider the fan pattern is. A zero degree nozzle sprays in a pencil point pattern, which is a straight stream.
Why do airless spray guns have more control over fan width than conventional spray guns?
Airless spray guns have more control over the fan width than conventional spray guns because the coating is forced through the tip without being atomized by air. This causes the tip to have a large impact on the fan width and shape.
How to determine the size of a coating tip?
There are three main factors to consider when determining the size tip that will produce the best results. First, examine the coating that will be sprayed. Put simply, heavier coatings will require a larger orifice size than lighter ones.
Why do you need a small fan for spraying?
Smaller surfaces will require a small fan width to reduce overspray. This also makes it possible to spray further away from the surface without too much falloff because the fan is more focused. Lastly, consider the spray gun that is being used. Make sure that the spray tip you plan on using will be supported by the gun.
