Hunter’s revolutionary MP Rotators use multi-stream technology to deliver accurate streams of water with superior uniformity. When used in place of standard spray nozzles, it’s not uncommon to see system water use decrease by up to 30% or more. This technology and water savings is brought to life in the PRS40. This efficient watering tool combines the rugged Pro-Spray body and replaces the traditional nozzle with a MP Rotator. Regulated at 40PSI, the Pro-Spray PRS40 ensures the optimum output pressure to achieve maximum efficiency. It is recommended for both residential and commercial applications, and is available in an array of configurations to suit the needs of any site.

This pressure-activated, multi-function wiper seal was designed to reduce flow-by. The zero flush seal operates at low pressures and allows more sprinkler heads to be installed on the same zone. The wiper seal’s design protects the riser when operating, and keeps debris out of the seal when retracted, reducing riser stick-ups.
The Pro-Spray line incorporates a heavy-duty ribbed body and durable cap engineered to withstand the harshest environments, including the rigors of foot traffic and the abuses of heavy machinery. In addition, the buttress thread design provides superior strength in cap-to-body gripping capacity helping the head to withstand high inlet surge pressures.
The industry's strongest spring for positive retraction under any conditions.
Optional check valves eliminates drainage at heads installed on slopes, protecting landscapes from damage and erosion while reducing water waste. Choose from the convenience of factory-installed check valves or the flexibility of field installation.
