f) Nozzle 

To select the correct nozzle size, determine the pressure (PSI) and flow (GPM) rating of your 
pressure washer.  This can be found on the manufacturer’s serial plate or literature. 
 
Using the chart for nozzle requirements (see Figure 3 below) read across the top to the PSI of 
your pressure washer then read down the column to the GPM of your pressure washer.  The 
correct orifice size is the number in the far left column.  Most manufacturers will imprint an 
identification code that will tell you the spray angle and the orifice size.  For example, “25040” 
means the nozzle has a spray angle of 25

°

 and has a 4.0 size orifice.
