Hunter Institutional Spray Sprinkler
Pop-Up Spray Heads

Note:  Nozzles Not Included


Rugged, water-saving sprinklers designed for commercial, institutional, and public area applications.

Exceptional strength, innovative features…just the need for high traffic areas. Features like a positive-seal flush cap with an innovative pull-up design that keeps debris out. A high quality, multi-functional, pressure-activated wiper seal. True pressure regulation under a wide range of environmental and pressure conditions to reduce water waste. An in-stem regulator that acts as a flow control device if the nozzle is removed. A super heavyduty check valve assembly that eliminates the potential liability issues of low head drainage. The most powerful retraction spring in its class. Sounds like a lot in a spray sprinkler? How about one more great feature–just like all other Hunter Institutional Series™ irrigation products, it carries a 5-year warranty.
