How to Order a Shamrock Nozzle

Shamrock Nozzles

Although nozzles are named and grouped according to their most popular use, many have multiple applications.  Ordering a variety of nozzles and associated tools will help you be ready to tackle any cleaning job.  For those tough emergencies where you need a little extra assistance, you can contact us at (800) 633-7696. A product specialist will help you select the right tool for the job. (Always mention special conditions such as lateral line applications.)

  • A front jet is standard on all Shamrock nozzles except the rotator nozzles. Many nozzles may be ordered without the front jet on request.
  • Nozzles ordered for flow rates of 80 GPM or higher have 10 rear jets.
  • All 1/2″ nozzles can be used on 1/2″ or 5/8″ hose.

Proper nozzle selection depends upon the hose size, flow rate and pressure of your pumping equipment. Some nozzles are available only in a certain size range to assure top efficiency and long service. Please use the table provided below to assist when ordering.


Identify the inside diameter of your hose.

Match the hose diameter to your desired flow rate. Identify the pressure of your pumping equipment.
