The RK-43 is a 1" MNPT full-circle brass impact sprinkler with an 18° trajectory — a mid-low angle suited to large-flow systems in orchards, under-canopy settings, and sites where wind resistance is needed at the 1" connection size. Its 9/32" x 3/16" dual nozzle set delivers high flow rates through a flatter arc than the standard 27° models.

RK-43 – 1" MNPT Full Circle Brass Impact Sprinkler (18°)
The RK-43 is a 1" MNPT full-circle brass impact sprinkler with an 18° trajectory. Fitted with dual 9/32" x 3/16" nozzles, it delivers high-volume flow in a lower-angle profile than the standard 27° impact heads — making it suitable for orchard and under-canopy irrigation at the 1" system size, or for exposed field sites where wind interference reduces pattern effectiveness at steeper angles.
Key Features and Benefits
- 18° trajectory — flatter arc reduces wind drift while maintaining a longer effective throw than very low-angle heads.
- 1" MNPT connection — standard male thread for large-flow agricultural laterals and risers.
- Dual nozzle set (9/32" x 3/16") — high-volume nozzles for large-system designs.
- Full-circle coverage — uniform distribution around each riser.
- Bronze body and arm — corrosion-resistant for heavy-use agricultural applications.
- Brass nut and tube — precise nozzle alignment for consistent distribution.
- Stainless steel spring and pin — reliable impact drive with low maintenance needs.
Construction
Bronze body and arm, brass nut and tube, stainless steel spring and pin. Spring arm impact drive.
