Rain Bird U-12F dual-orifice spray nozzle - 360° full-circle - 2.7 to 3.7 m radius

Rain Bird U-12F dual-orifice full-circle spray nozzle

The Rain Bird U-12F is a high-efficiency dual-orifice spray nozzle with a fixed 360° full-circle spray pattern and a radius of 2.7 to 3.7 m. It is particularly suitable for automatic irrigation of central lawn areas and larger, continuous landscaped spaces. Since the nozzle distributes water in every direction, it is an ideal choice for sprinklers positioned within a lawn where complete circular coverage is required.

As part of the Rain Bird U-Series, the U-12F features two separate spray openings. The main opening distributes water toward the outer edge of the spray pattern, while the additional opening delivers water close to the sprinkler head. This design supports more uniform watering across the entire circular area.

360° full-circle coverage with a 3.7 m radius

The fixed 360° spray pattern allows the Rain Bird U-12F to water the entire area surrounding the sprinkler. This makes it especially suitable for pop-up sprinklers installed within a lawn rather than along its boundaries. Unlike quarter-circle and half-circle nozzles, the full-circle version does not require adjustment of the spray sector.

The spray radius ranges from 2.7 to 3.7 m depending on operating pressure. At the recommended pressure of 2.1 bar, the nozzle reaches approximately 3.7 m. Its 23° spray trajectory supports water distribution over the longer radius. An integrated stainless steel adjustment screw allows the radius to be reduced when necessary.

Dual-orifice technology for uniform water distribution

The distinguishing feature of the Rain Bird U-12F is its additional spray opening for close-in watering. Conventional spray nozzles may deliver less water immediately around the sprinkler head. The secondary opening helps address this by directing water into the area closest to the sprinkler body.

Improved close-in coverage helps reduce dry patches and supports more consistent watering across the lawn. According to Rain Bird, U-Series nozzles can reduce water consumption by up to 30% compared with conventional spray nozzles under suitable installation conditions. Actual savings depend on sprinkler spacing, operating pressure and watering schedules.

Easy installation and combination with other U12 nozzles

The Rain Bird U-12F is compatible with Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series. A fine mesh filter screen helps protect the lower spray opening from debris. For installations with higher water pressure, pressure-regulated spray bodies can help maintain consistent nozzle performance.

When planning your irrigation system, the U-12F can be combined with suitable U-12Q quarter-circle and U-12H half-circle nozzles. Consider their different flow rates and ensure sufficient overlap between adjacent spray patterns. Because the full-circle version waters a larger area, it requires more water than the quarter-circle and half-circle models at the same pressure.

Frequently asked questions about the Rain Bird U-12F

What is the spray radius of the Rain Bird U-12F?

The spray radius ranges from 2.7 to 3.7 m depending on operating pressure. At 2.1 bar, the nozzle reaches approximately 3.7 m.

Can the 360° spray angle be adjusted?

No. The U-12F has a fixed full-circle spray pattern. However, the radius can be reduced using the integrated stainless steel adjustment screw.

How much water does the U-12F use?

The flow rate ranges from 6.8 to 9.8 l/min, equivalent to approximately 408 to 588 litres per hour, depending on pressure.

Why does the nozzle have two spray openings?

The additional opening distributes water close to the sprinkler head, helping improve watering uniformity and reduce dry patches around the spray body.

Which sprinkler bodies are compatible?

The Rain Bird U-12F is compatible with Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series.

Can the U-12F be combined with other U12 nozzles?

Yes. The U-12F can be combined with suitable U-12Q quarter-circle and U-12H half-circle nozzles. Their different flow rates should be considered when designing the irrigation zone.
