Hunter Institutional Spray

Description

Exceptional strength, innovative features…just the need for high traffic areas. Features like a positive-seal flush cap with an innovative pullup 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 heavy-duty 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 SeriesTM irrigation products, it carries a 5 year warranty.
