1/2" Plastic Butterfly Mini-Sprinkler – 11/64" Nozzle – Full Circle
$2.35
1/2" plastic butterfly mini-sprinkler with 11/64" nozzle — designed for under-tree irrigation in orchards, nurseries, and other low-profile applications. The spinner-driven full-circle pattern delivers uniform coverage at low pressures (14–28 PSI) with flow rates from 2.7 to 3.8 GPM and a throw radius of 19–21 feet. The largest nozzle in the RK-20 series for higher application rates.

RK-20R – 1/2" Plastic Butterfly Mini-Sprinkler with 11/64" Nozzle
The RK-20R is a compact, spinner-driven butterfly mini-sprinkler designed for under-tree and low-profile irrigation in orchards, nurseries, and row crops. Its full-circle spray pattern delivers uniform water distribution across a 19–21 ft. radius at operating pressures as low as 14 PSI. The 11/64" nozzle is the largest in the RK-20 series, providing the highest application rate.
Key Features & Benefits
- Butterfly spinner design — creates a wide, uniform spray pattern ideal for under-canopy coverage without wetting foliage
- Low-pressure operation (14–28 PSI) — reduces energy costs and works well on gravity-fed or low-pressure systems
- 11/64" nozzle — the largest nozzle option in the RK-20 series, delivering 2.7–3.8 GPM for higher application rates on thirstier crops or sandier soils
- Full-circle coverage — 19–21 ft. throw radius provides effective coverage for typical orchard and nursery spacing
- 1/2" MNPT connection — threads directly onto standard risers and poly tubing fittings
- Lightweight plastic construction — resists corrosion, UV degradation, and chemical damage from fertigation solutions
Ideal Applications
Under-tree irrigation in citrus groves, nut orchards, vineyards, and nurseries. The higher flow rate makes this nozzle a good choice for sandy soils or crops with higher water demands. Also suitable for greenhouse bench irrigation.
