Rain Bird U-8Q dual-orifice spray nozzle - 90° quarter-circle - 1.7 to 2.4 m radius

Rain Bird U-8Q dual-orifice quarter-circle spray nozzle

The Rain Bird U-8Q is a high-efficiency dual-orifice spray nozzle with a fixed 90° quarter-circle spray pattern and a radius of 1.7 to 2.4 m. It is designed for automatic irrigation of small lawns, garden corners and rectangular landscaped areas. Its two spray openings distribute water both close to the sprinkler head and across the outer section of the watering area.

As part of the Rain Bird U-Series, the U-8Q is designed to improve water distribution and reduce dry spots around pop-up sprinklers. It can be installed on compatible Rain Bird spray bodies and is suitable for both new irrigation systems and replacing existing spray nozzles.

Dual-orifice design for more uniform watering

Conventional spray nozzles may deliver less water immediately around the sprinkler head. The Rain Bird U-8Q addresses this with an additional spray opening that directs water into the close-in area. The second opening distributes water toward the outer edge of the quarter-circle spray pattern.

This combination helps create more uniform coverage across the irrigated area, reducing the risk of dry patches close to the sprinkler. According to Rain Bird, U-Series dual-orifice nozzles can use up to 30% less water than conventional spray nozzles when installed throughout a properly designed irrigation zone. Actual savings depend on the installation and operating conditions.

Fixed 90° spray pattern for corners and lawn edges

The Rain Bird U-8Q features a fixed quarter-circle spray angle of 90°, making it particularly suitable for garden corners and lawn areas bordered by paths, patios or flower beds. The defined spray pattern helps direct water onto the intended area rather than surrounding surfaces.

The spray radius ranges from 1.7 to 2.4 m depending on operating pressure. At the recommended pressure of 2.1 bar, the nozzle achieves a radius of approximately 2.4 m. Its 10° trajectory produces a relatively low spray pattern. An integrated stainless steel adjustment screw allows the radius to be reduced when necessary.

Easy installation on Rain Bird spray bodies

The U-8Q is designed for use with Rain Bird spray bodies and compatible spray adapters. It is particularly suitable for pop-up spray heads from the Rain Bird 1800 Series. For installations with higher water pressure, Rain Bird recommends pressure-regulated spray bodies to maintain more consistent nozzle performance.

When planning your irrigation system, select the appropriate nozzle radius and spray pattern for each section of lawn. Allow sufficient overlap between adjacent sprinklers to achieve even water distribution. This helps provide reliable coverage while avoiding unnecessary water consumption.

Frequently asked questions about the Rain Bird U-8Q

What is the spray radius of the Rain Bird U-8Q?

The spray radius ranges from 1.7 to 2.4 m depending on water pressure. At 2.1 bar, the nozzle achieves approximately 2.4 m.

Can the spray angle be adjusted?

No. The U-8Q has a fixed 90° quarter-circle spray pattern. Half-circle and full-circle models are available separately in the Rain Bird U-Series.

What is the benefit of a dual-orifice nozzle?

The additional spray opening distributes water close to the sprinkler head, helping provide more uniform coverage and reducing dry patches near the spray body.

How much water does the U-8Q use?

The flow rate is approximately 0.7 to 1.0 l/min, equivalent to about 42 to 60 litres per hour, depending on operating pressure.

Which sprinkler bodies are compatible?

The Rain Bird U-8Q is compatible with Rain Bird spray bodies and suitable adapters, including models from the Rain Bird 1800 Series.

Can the spray radius be reduced?

Yes. The integrated stainless steel adjustment screw allows the spray radius to be reduced. Actual performance also depends on the water pressure at the nozzle.
