RK-30 – 3/4" MNPT Full Circle Brass Impact Sprinkler (27°)

The RK-30 is a 3/4" MNPT full-circle brass impact sprinkler with dual 11/64" x 1/8" nozzles, a flow range of 3.1–13.9 GPM, and a radius of 33.8–59 ft. Operating across a wide 30–70 PSI pressure window, it is the most versatile and most popular agricultural impact sprinkler in the RK lineup — suitable for row crops, pastures, orchards, nurseries, and general field irrigation on small to medium farms.

Key Features and Benefits

• 3/4" MNPT connection — the standard size for the majority of agricultural riser and lateral systems, ensuring broad compatibility.
• Dual nozzle set (11/64" x 1/8") — two nozzles allow the operator to select the flow rate that matches system design without changing the sprinkler body.
• 27° trajectory — the industry-standard angle for optimum throw distance and distribution uniformity in open field conditions.
• Wide flow range (3.1–13.9 GPM) — accommodates a broad range of system pressures and spacings.
• Bronze body and arm — corrosion-resistant for long service life in continuous-run and chemigation applications.
• Brass nut and tube — precise nozzle alignment for consistent distribution uniformity across a field.
• Stainless steel spring and pin — corrosion-resistant impact drive for low-maintenance seasonal and year-round operation.
