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.
