It’s best of the best in its category, with ultra exceptional water-conserving features that make it ideal for today’s environment. It’s a given: high traffic areas demand a product that reduces water waste with hard-working pressure regulation under a wide range of conditions. The built-in pressure regulator provides an optimum 30 PSI (2 bars) to the nozzle. It also has the toughest spring in its class. When it comes to the I-Spray, the benefits are clear.

Maximum nozzle efficiency whatever the inlet pressure.

Tough-As-Nails Body and Body Cap Construction:
Buttress threads for harsh conditions.

Pressure-Activated, Multi-Function, No-Flow-By Wiper Seal:
Tired of the sun trashing your wiper seals? Not a concern for years to come.

Works With All Female Threaded Nozzles:
Like our new adjustable nozzles and fixed arc nozzles.

Install Check Valves from the Factory or in the Field When Needed:
