The Short Answer
Pressure washer nozzle tips are color coded by degree: red is 0 degrees, yellow is 15, green is 25, white is 40, and black is 65, where the degree number is the width of the spray fan and the color tells the operator which one is in hand. The narrow degrees concentrate the stream for stripping, and the wide degrees spread it for rinsing and gentle work. The color is the warning label, and the degree is the number behind it.
The pattern is the power. A lower degree number means a narrower fan and more force on the surface, and a higher degree number spreads the same pressure over more area. The 0 and 15 degree tips strip, the 25 and 40 degree tips clean, and the widest tip rinses and protects. Same machine, different tip, completely different behavior.
Nozzle Tip Colors, Degrees, and Spray Patterns
The red tip at 0 degrees is the narrowest spray pattern in the set: a pinpoint stream that puts the machine's whole pressure on a single point. That concentration makes it the stripping tool for the toughest buildup, and it makes it the most dangerous tip in the box, because the same point that strips concrete will cut soft surfaces and etch seams. The 0 degree tip is a laser wearing a color. Point it like it costs money, because it does.
The yellow tip at 15 degrees widens the spray pattern just enough to cover a line of work while keeping the force that strips. It is the commercial workhorse for heavy buildup: concrete stains, gummed flatwork, and the surfaces the route is actually paid to reclaim. The 15 degree tip does the stripping the 0 degree tip does with a fraction of the single-point risk. Yellow is the tip that turns pressure into production. The strip-it lane runs through the yellow tip.
The green tip at 25 degrees is the everyday spray pattern of the route: wide enough to cover surface area fast, moderate enough to clean without the strip-it aggression. Siding, walkways, and routine washdowns all run through the green tip, which makes it the default for the jobs that are not battles. Green is the tip that does the daily work without the drama. Most of the route lives in the 25 degree lane.
The white tip at 40 degrees and the black tip at 65 degrees are the wide end of the chart: fans that spread the stream across the surface for rinsing, chemical application, and the gentle work. The wide patterns drop the force per square inch, which is why the soft surfaces of the route, wood, vehicles, and delicate siding, run on these tips. The wide tips are where pressure learns manners. The rinse pass is a wide-fan job, and the wide fans protect everything downstream.
The degree number is the width of the spray pattern, and the pattern is what spreads or concentrates the pressure. The same machine that strips with the 15 degree tip rinses gently with the 65 degree tip, because the force spreads across a wider fan. Reading the chart is the skill that keeps one machine safe on every surface of the route. The degree is the dial, and the color is the label. Change the tip, change the machine.
| Color | Degrees | Spray pattern | Use |
|---|---|---|---|
| Red | 0 | Pinpoint | The toughest single-point stripping |
| Yellow | 15 | Narrow fan | Heavy buildup and concrete stains |
| Green | 25 | Medium fan | Everyday cleaning of siding and walkways |
| White | 40 | Wide fan | Rinsing and general washdowns |
| Black | 65 | Widest fan | Gentle work and chemical application |
What This Means for Your Operation
Carry the color set and read the surface before the trigger. Red and yellow strip, green cleans, and the wide white and black tips rinse and protect. The PSI by surface guide pairs the tip choice with the surface reading for the full route.
