What do pressure washer nozzle colors mean? The color of the nozzle identifies the angle of the spray fan pattern measured in degrees and is generally the same across all sizes. Red is 0, Yellow 15, Green 25, and White 40. The black nozzle is used for applying soap at low pressure and is sometimes used for low pressure rinsing.

How do you change the nozzle on a Craftsman pressure washer? – Related Questions
What nozzle to use to pressure wash a driveway?
What do the numbers on a pressure washer nozzle mean?
Pressure Washer Spray Nozzle can be identified by the nozzle “number”, a four or five digit number that is stamped on the nozzle, which indicates the spray angle and orifice size. In all cases the first two digits of the nozzle number indicate the spray angle (disperse) in degrees.
How do I choose a nozzle size?
The correct nozzle height is measured from the nozzle to the target, which may be the top of the ground, growing canopy, or stubble. Use 110-degree nozzles when booms are less than 30 inches high with 30-inch nozzle spacing; use 80-degree nozzles when the booms are higher.
How do you calculate nozzle size?
To find the correct nozzle size you need to know the flow of your system and the pressure you wish to achieve. First, select the column with the required pressure across the top, then read down the column to find the amount of flow of your system.
How do I fix the nozzle on my pressure washer?
Do pressure washer tips change the pressure?
The tip and nozzle of your wand are not what creates the pressure from your machine. That is created internally with the pressure washer pump. The tips are used so you can adjust the opening that the wand will spray out of the wand with. A larger opening will create a larger spray surface and less power to clean with.
How do you remove a pressure washer nozzle?
1. Switch the pressure washer off by turning the power dial to the position that is marked ‘0’. 2. Twist the nozzle where it meets the trigger handle counterclockwise which detaches it from the pressure washer.
When should I use pressure washer turbo nozzle?
You would use a turbo nozzle when tackling a stubborn cleaning job. The higher power will help you clean up mold, dirty concrete, caked-on mud, oil stains, etc.
What is 0 degree pressure washer nozzle used for?
Red-Colored Zero Degree Nozzle Delivers a small, very concentrated stream of water. This nozzle is typically used for removing tough stains and debris from concrete and metal.
How do you read a nozzle chart?
On a standard nozzle chart, the top column that runs left to right is the pressure that you want to obtain. The left column top to bottom is the nozzle orifice size designation. The top to bottom column next to the orifice size column indicates the actual orifice measurement.
Is a turbo nozzle worth it?
Turbo nozzles have been one of the most important accessories developed. These efficient tools provide the power of a zero-degree pattern. The circular motion also adds extra agitation to cleaning tough jobs like caked-on mud. They are designed to provide a 200% cleaning efficiency over a 25-degree flat fan nozzle.
Do high pressure hose nozzles work?
The Big Shot high pressure hose nozzle does a great job of recreating a high pressure washer. The stream can be focused to a thin stream which is perfect for cleaning a small area. It is also very economical both in price and size.
Can you damage concrete by power washing?
The quick answer is yes, power washing can degrade a concrete surface. You can notice visible damage from water pressure at the level at which even light-duty power washers can operate. Therefore, if you aren’t careful, you can cause irreversible damage to your driveway or patio.
What do you spray on concrete before pressure washing?
Applying a degreaser will loosen stains in the concrete, allowing you to pressure wash them away. Some pressure washers have an attachment tool for applying degreaser. Otherwise, scrub the degreaser into the concrete with a stiff-bristled brush or push broom.
How much PSI do you need to clean a house?
For cleaning your house’s driveway, you need a pressure washer set to 2,500 to 3,000 psi. For other areas, like the vinyl sidings, decks, or glass, the pressure should not exceed 1,500 psi. For soft materials, like softwood, you should use even lower pressure, around 500 to 600 psi.
What do the nozzle sizes represent?
Choosing the Right Nozzle for Your Machine 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. This causes the pressure to increase.
How do I choose a spray nozzle?
Selecting Your Nozzle Size 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).
What are the different types of nozzles?
- The Nozzle Tip is one of the most important and least expensive part of a spraying system. Adjustable nozzle.
- Double swirl spray nozzle.
- Selecting a spray nozzle.
- Hollow cone nozzles-Disc and core type.
- Flat fan nozzles.
- Floodjet nozzles.
- Adjustable nozzles.
Does nozzle size affect layer height?
A nozzle with a larger diameter also allows for printing with increased layer height. Combining these two effects leads to a noticeably shorter print time.
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.
How do you calculate water flow from pressure?
The Bernoulli equation states that velocity is determined by calculating difference in pressure between two points, multiplying by 2, dividing by the density of water and then taking the square root. You then get the flow rate by multiplying the velocity by the cross-sectional area of the pipe.
How far apart should spray nozzles be?
Nozzle Spacing The most common nozzle spacings are 20 and 30 inches. Many sprayers are now being converted from 30 inch to 15 inch spacings. The 30-inch spacing is used for the lower application rates (7 to 10 gallons per acre) and the 15-inch spacing for the higher application rates (14 gallons per acre and higher).
How will you select a nozzle for a particular type of job?
- Select the application rate in gallons per acre (gpa). …
- Select a practical and safe ground speed in miles per hour (mph).
- Determine the spray width per nozzle (W).
- Determine the flow rate (gpm) required from each nozzle by using the following equation:
What’s the difference between pressure washer nozzles?
Nozzles Explained Each nozzle that you add to the end of the wand will spray water in a wider or narrower V, depending on what degree angle it is designed to spray at. For example, a 15° angle is a fairly narrow V, while a 40° is significantly wider.
What is the red nozzle on a pressure washer?
