Pressure washer nozzles control the spray angle and intensity of water coming out of your machine. Choosing the right nozzle makes cleaning faster, safer and more effective — but using the wrong one can cause damage or poor results. This guide explains what each nozzle does and when to use it.
Quick Answer: Pressure washer jet nozzles control the spray angle and pressure intensity, with different colours representing specific spray patterns for tasks like rinsing, general cleaning, or heavy-duty dirt removal.
The Five Main Pressure Washer Nozzle Types
Most pressure washers use colour-coded nozzles. Here’s what each one means:
0° Nozzle (Red – Maximum Power)
- Very strong, concentrated jet
- Best for metal, stone and stubborn dirt
- Never use on cars, wood, paint or delicate surfaces
15° Nozzle (Yellow – Heavy Cleaning)
- Powerful but safer than 0°
- Great for driveways, brick, tools and machinery
- Often used for surface prep like removing old paint
25° Nozzle (Green – General Cleaning)
- Balanced cleaning power and safety
- Ideal for patios, decks, fences and garden furniture
- The most versatile home-use nozzle
40° Nozzle (White – Gentle Cleaning)
- Wide spray for light cleaning
- Safe for cars, windows, bikes, outdoor fabrics
- Good for rinsing and applying detergents
Turbo Nozzle (Rotating Jet)
- Combines 0° power with a rotating spray pattern
- Cuts through deep grime on stone, concrete and brick
- Not suitable for delicate surfaces
