Nozzle Selection Guide
Spray nozzles can be identified by the nozzle “number”, a five or six digit number that is stamped on the nozzle, which indicates the spray angle and orifice size. In most cases the second and third digits of the nozzle number indicate the spray angle in degrees. Example: 00 is 0 degrees, 15 is 15 degrees and 40 is 40 degrees. The last two numbers of the nozzle number indicate the orifice size, a standard industry designation. Example: 60 is a 6.0 orifice, 55 is a 5.5 orifice. These numbers correspond to the actual dimensions, giving the size of the orifice. They do not, however, directly indicate gallons per minute, flow rates or inches in diameter of the orifice. Some power washers come with an adjustable nozzle, which is fixed to the end of the wand. The fan spray may be adjusted by turning the nozzle and chemicals may also be applied by pulling outward on the nozzle.

The spray force from nozzles can cause injuries if pointed directly at yourself or others. Before observing nozzles directly always disconnect them from your spray wand.
