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.
What is the difference in pressure washer tips?
Most pressure washers have the standard red, yellow, green, and white spray tips as attachments to the wand. The black nozzle will help with soaping a surface, and the turbo nozzle combines pressure and wide water angle hitting your target.
How do I know what pressure washer tip I have?
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.
What nozzle to use to pressure wash a driveway?
Use a 25-degree nozzle for deep cleaning and a 40-degree nozzle for rinsing away standing water.
What do the different pressure washer nozzles do?
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.
Are power washer attachments universal?
Gas pressure washers are more universal, making it easier to match various accessories and couplings to them. However, electric pressure washers will be mostly brand specific, meaning only specific accessories or parts from the same manufacturer will be compatible.
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.
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. This causes the pressure to increase. Choosing a nozzle with too large of an orifice will reduce operating pressure.
Does a turbo nozzle increase PSI?
A turbo nozzle temporarily replaces the fan nozzle on your water blaster to increase cleaning pressure by about 60%. For example, it would increase this Washmate-10’s pressure from 2,200 psi to around 3520 psi.
What tip should I use for concrete?
0° Red nozzle
The red-colored nozzle is the most powerful and often used for concrete cleaning.
What do the colors on pressure washer tips 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 many PSI Do I need to clean concrete?
What PSI pressure washer do I need to clean concrete? To clean concrete effectively, use a power washer with a pressure rating of at least 3000 psi and a flow rate of at least 4 gallons per minute (gpm).
What pressure washer nozzle is safe for house?
Which Nozzle? You will need to use the black soaping nozzle to apply the detergent. Then to pressure wash the house siding clean use either the 25 or 40 degree nozzle tip. To pressure clean the higher up areas you will want to use an extension wand because you want to avoid using a ladder with a pressure cleaner.
Will a pressure washer work without a nozzle?
With no nozzle, only inlet water pressure (approximately 50 psi) will flow through the spray gun. Also, if a nozzle is sized too small, the machine will create more pressure—and if too large, less pressure.
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.
