Pressure washers are powerful tools that use high-pressure water sprays to clean a variety of surfaces. One important component of a pressure washer is the nozzle, which determines the spray pattern and intensity of the water.

When you look at a pressure washer nozzle, you may notice that it has a number on it. This number represents the size of the orifice, or the opening through which the water flows. The size of the orifice affects the pressure and spray pattern of the water coming out of the nozzle.

The most common numbering system for pressure washer nozzles is based on a color-coding system, which helps users easily identify the different spray patterns. Each color corresponds to a different spray angle, ranging from 0 degrees to 65 degrees.

For example, a nozzle with a 0-degree spray angle will produce a concentrated, high-pressure stream of water. This is often used for tough cleaning tasks that require a lot of power. On the other hand, a nozzle with a 65-degree spray angle will produce a wide, gentle spray that is ideal for delicate surfaces.

In addition to the spray angle, the number on the nozzle also indicates the flow rate, or how much water is being released per minute. A higher number means a higher flow rate, which can be useful for larger cleaning jobs.
