According to the manufacturer,out of the Chapin Fan Nozzle Kit (6-4824) the yellow nozzle would spray the most at .50 gallons per minute. The red is .25 gallons per minute, and the blue is .33 gallons per minute.
The Chapin Fan Nozzle Kit, like most Chapin parts, is very specific as far as which units it will fit on and can be used with. You would need to know the model number or full name of the sprayer you have for us or for Chapin to determine what nozzles you may need to work with your unit. You may also be able to take a clear picture of your Chapin sprayer to email to them directly or to us to try and identify the model you have.
