K-RAIN ROTATOR SPRAY DIY 3/4 K5

A 3/4-inch DIY gear-driven rotor sprinkler (K5 Select series) with built-in selectable nozzles, designed for efficient medium-range irrigation with adjustable arc and water-saving operation.

The K-Rain K5 Rotator Spray DIY 3/4 K5 (commonly known as the K5 Select Rotor) is a gear-driven irrigation rotor designed for residential and light commercial sprinkler systems. It replaces traditional spray heads or older rotors with a more efficient multi-nozzle rotary system.

This model features a patented built-in nozzle selector system, allowing users to choose between multiple integrated nozzles without replacing parts in the field. This makes it especially useful for DIY installations and quick system adjustments.

The rotor delivers a smooth reversing gear-driven rotation and supports adjustable arc settings from approximately 40° to 360°, making it suitable for corners, edges, and full-circle lawn coverage.

It is designed for medium to large lawn areas and provides matched precipitation, meaning all nozzles apply water at the same rate across different arc settings to avoid overwatering or dry spots. The K5 system is widely recognized as a replacement alternative to standard 3/4" rotors in irrigation systems.
