RS-7/64 Brass Secondary Nozzle 7/64" – For 3/4" Impact Head
$0.75
Replacement brass secondary nozzle sized 7/64" for 3/4" brass impact sprinkler heads (RK-30 series, RK-32, RK-35). The secondary nozzle mounts behind the main stream to irrigate the close-in area beneath the full-radius arc, eliminating dry zones near the riser. This size (7/64"): low close-in flow, small inner coverage radius. Pair with a primary nozzle (RK- series) or use the RP-1/8 plug if no secondary coverage is needed.

RS-7/64 – 7/64" Brass Secondary Nozzle for 3/4" Impact Sprinkler Heads
The RS-7/64 is a 7/64" brass secondary nozzle for 3/4" brass impact sprinkler heads including the RK-30 series, RK-32, and RK-35. The secondary nozzle occupies the port behind the main stream and directs water into the inner coverage zone — the area between the riser and the main stream's landing radius — which the primary nozzle alone does not reach. Selecting the right secondary nozzle size allows irrigation managers to balance close-in and far-field application rates for uniform coverage across the full wetted area.
Key Features and Benefits
- Size 7/64" — Low close-in flow, small inner coverage radius. Select based on desired inner-zone application rate and spacing.
- Eliminates dry inner zones — fills the close-in area that the primary nozzle's arc does not cover, improving uniformity across the full wetted diameter.
- Brass construction — durable, corrosion-resistant for continuous agricultural use.
- Works with the full primary nozzle range — pair any RS- secondary with any RK- primary to tune both inner and outer coverage independently.
- If no secondary is needed — use the RP-1/8 plug to seal the secondary port instead.
Compatibility
Fits 3/4" brass impact heads: RK-30, RK-30LA, RK-30PC, RK-32, RK-35, and related variants. Not for 1/2" or 1" heads.
