A definite WATER CONSERVATION TOOL
The MPR40’s pressure activated, multifunction wiper seal has been designed to reduce flow-by. The zero flush seal gives you surefire operation at low pressures and enables more sprinkler heads on the same zone. The wiper seal is designed to grip the riser when operating and keep debris out of the seal when retracted. No more body cap leaks either. Put debris in its place, and end riser stick-ups.

The MP Rotator and The MPR40: The partnership the performs.
From our work with the revolutionary MP Rotator evolved the origins of a great idea. To maximize the results of this multi-stream rotor, we pursued the next logical step. Introducing the MPR40—Calibrated at a consistent 40 PSI, it is designed to provide optimal performance when combined with the MP Rotator. Together, the two are a true blend of technology and performance. In fact, the MPR40 is the only product of its kind. Discover the MPR40. Paired with the MP Rotator, it’s a partnership that performs.

What Makes Hunter Sprinklers
the Easiest to Adjust?

Our new two-piece ratchet design—with independent ratcheting ring—facilitates quicker, more precise sprinkler head adjustment. With
its tough-as-nails, abrasion resistant, high impact
material, it withstands any impact in higher pressure
systems. Incredibly dirt tolerant, too. What more can we say?
