What size of nozzle should I use on my pressure washer?

Choosing the proper nozzle size for your pressure washer is very important, if you choos the wrong size orifice you can do damage to the pressure washer pump or not be able to acheive the proper pressure for your application.

In order to choose the right nozzle you must know 2 things about your Pressure washer; the Gallons per Minute that it operates at and the Pressure (Pounds per square inch) that is produced. After these variables are known about your pressure washer you can use the following equation to find the right nozzle orifice size:

nozzle size equals the gallons per minute times the square root of 4,000 divided by the desired pressure

Or use this chart to figure out the size you need:

What type of nozzle should I use on my sprayer?

Types of nozzles:

  • Flat fan
  • Flood
  • Raindrop
  • Hollow-cone
  • Full-cone
  • Fine hollow cone

Red nozzles or 0 degree nozzles produce a narrow, powerful stream of water. This nozzle is good for very difficult to remove dirt, stains and grime.

Yellow nozzles or 15 degree nozzles produce a small angle of spray for focused cleaning. This nozzle is good for somewhat difficult to remove dirt and grime.

Green nozzles or 25 degree nozzles produce a medium angle of spray for washing sensitive or soft surfaces such as decks, aluminum and fencing.

White nozzles or 40 degree nozzles have the largest angle of spray and are used for cleaning surface quickly and for rinsing.

Black nozzles or 65 degree nozzles are the only nozzle that can be used with cleaning solutions.
