  2. Flow rate - the flow rate is represented as a number usually between 015 and 08. These     numbers refer to the flow rate in US gallons at the rated pressure of 40 PSI (approx. 3 BAR). For example, an 02 Nozzle is rated at 0.2 US gallons per hour at a pressure of 40 PSI. We use litres per minute but still that is the history of how the numbers came into being.
  3. The colour - Nozzles have ISO standard colour. For example an 02 nozzle is always yellow, and an 04 nozzle is always red. See the chart below for what all of the nozzle colours mean.
