The RK-25 is a part-circle brass impact sprinkler for boundary rows, field edges, and any layout where full 360° coverage would waste water beyond the irrigated area. Its diffuser screw allows the operator to reduce throw radius on-the-fly for fine-tuned coverage at field edges and around obstacles.

RK-25 – 1/2" MNPT Part Circle Brass Impact Sprinkler (25°) with Diffuser Screw
The RK-25 is a 1/2" MNPT part-circle brass impact sprinkler with a 5/32" nozzle, flow range of 2.5–5.1 GPM, and a radius of 34.8–41 ft at 30–55 PSI. The adjustable part-circle arc and built-in diffuser screw give operators precise control over both coverage angle and throw distance — making it ideal for field perimeters, border rows, and irregularly shaped blocks.
Key Features and Benefits
- Part-circle arc adjustment — limits coverage to the irrigated zone, preventing water waste on roads, structures, and non-crop areas.
- Diffuser screw — allows radius reduction without changing nozzles, enabling quick field adjustments for edge rows and obstacle clearance.
- 5/32" nozzle — sized for moderate flow applications in 1/2" systems.
- Bronze body and arm — corrosion-resistant construction for continuous field service.
- Brass nut and tube — precise nozzle alignment for consistent distribution uniformity.
- Stainless steel spring and pin — low-maintenance impact drive that resists corrosion and fatigue.
Construction
Bronze body and arm, brass nut and tube, stainless steel spring and pin. Spring arm impact drive.
