Pressure Washer Nozzles, Guns, Wands, and Spray Tips - 155

These colour coded pressure washer spray tips incorporate a straight through plug to connect to a corresponding coupler (i.e. 1/4" CST4B). The orifice size of the nozzle determines the operating pressure of your machine. As a rule of thumb, the smaller the orifice, the greater the restriction of water flowing through the machine, and hence increased pressure. Therefore, choosing a nozzle with too large of an orifice will reduce operating pressure, and choosing a nozzle with too small an orifice will limit water flow and possibly create an excessive load on the machine. Available orifice sizes are listed in the table below.
