RK-9/64 – 9/64" Brass Primary Nozzle for 3/4" Impact Sprinkler Heads
The RK-9/64 is a 9/64" brass replacement primary nozzle for 3/4" brass impact sprinkler heads including the RK-30 series, RK-32, and RK-35. The primary nozzle is the main flow orifice and the single most influential factor in determining each head's flow rate, throw radius, and application rate. Field-replaceable without tools, allowing operators to tune system output by nozzle swap rather than replacing entire heads.
Key Features and Benefits
- Size 9/64" — Mid-low flow, mid radius. Match to your available pressure, head spacing, and required application rate.
- Brass construction — corrosion-resistant for reliable long-term performance in continuous-run and chemigation systems.
- Nozzle sizing principle — smaller orifice reduces flow and radius; larger orifice increases both. Always confirm against manufacturer performance charts for the specific head model.
- Quick field swap — replace in seconds to adjust coverage across zones or compensate for pressure variation.
Compatibility
Fits 3/4" brass impact sprinkler heads: RK-30, RK-30LA, RK-30PC, RK-32, RK-35, and related variants. Not for 1/2" (RKS-) or 1" (RK-L) heads.
