Rain Bird U-12Q dual-orifice spray nozzle - 90° quarter-circle - 2.7 to 3.7 m radius

Rain Bird U-12Q dual-orifice spray nozzle for larger lawn corners

The Rain Bird U-12Q is a high-efficiency dual-orifice spray nozzle with a fixed 90° quarter-circle spray pattern and a radius of 2.7 to 3.7 m. It is particularly suitable for automatic irrigation of lawn corners and rectangular landscaped areas where a longer spray radius is required. The defined quarter-circle pattern helps direct water onto the intended lawn area without unnecessarily watering surrounding surfaces.

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

90° quarter-circle coverage with a 3.7 m radius

The fixed 90° spray angle makes the Rain Bird U-12Q an excellent choice for sprinklers installed in corners. It is particularly useful where lawn areas are bordered by patios, garden paths, walls or flower beds. Its spray pattern helps keep irrigation water within the intended area.

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 achieves approximately 3.7 m. The 23° spray trajectory supports water distribution over the longer radius. An integrated stainless steel adjustment screw allows the radius to be reduced when required.

Dual-orifice technology for improved close-in watering

The distinguishing feature of the Rain Bird U-12Q is its dual-orifice design. Conventional spray nozzles may deliver less water immediately around the sprinkler head. The additional opening of the U-12Q addresses this by directing water into the close-in area.

This design helps reduce dry patches near the sprinkler body and improves water distribution throughout the watering area. 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 on Rain Bird spray bodies

The Rain Bird U-12Q is designed for compatible Rain Bird spray bodies and 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 help maintain more consistent nozzle performance.

When planning your irrigation system, the U-12Q can be combined with suitable U-12H half-circle and U-12F full-circle nozzles. Make sure the available water supply is sufficient for the total flow demand and position sprinklers with adequate overlap to achieve even lawn coverage.

Frequently asked questions about the Rain Bird U-12Q

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

The 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.

Can the 90° spray angle be adjusted?

No. The U-12Q has a fixed quarter-circle spray pattern. Half-circle and full-circle versions are available separately in the U12 Series.

How much water does the U-12Q use?

The flow rate ranges from 1.7 to 2.5 l/min, equivalent to approximately 102 to 150 litres per hour, depending on operating pressure.

Why does the nozzle have two spray openings?

The additional opening directs 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-12Q is compatible with Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series.

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

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