Rain Bird 1800-EXT spray head extension tube - 16.5 cm

Rain Bird 1800-EXT for raised spray nozzles

The Rain Bird 1800-EXT spray head extension allows you to raise the position of a compatible spray nozzle by an additional 16.5 cm. This practical accessory is designed for Rain Bird spray bodies and suitable nozzles. It is particularly useful in planting beds, groundcover areas and locations with taller vegetation, where a higher nozzle position can help distribute water above surrounding plants.

The extension is installed between the spray head and its nozzle, allowing you to increase the spray height without replacing the complete sprinkler body. This provides a convenient way to adapt an existing irrigation system to changing plant heights or new garden requirements.

16.5 cm additional height per extension

Each Rain Bird 1800-EXT raises the spray nozzle by 16.5 cm. If one extension is insufficient, Rain Bird recommends using no more than two extensions per sprinkler. This provides up to 33 cm of additional nozzle height. The extensions can be connected together to adjust the spray position to the required level.

Raising a spray nozzle can help overcome obstacles such as foliage, low shrubs and groundcover. During installation, ensure that the nozzle has a clear spray path and that the extension is securely fitted. Spray distance and water consumption continue to depend on the selected nozzle and available operating pressure.

Compatible with Rain Bird spray bodies and nozzles

The Rain Bird 1800-EXT is designed for Rain Bird spray bodies and compatible spray nozzles, including popular models from the Rain Bird 1800 Series. It can be used with various suitable nozzle types, including fixed-pattern and adjustable-arc spray nozzles. This makes the extension a versatile accessory for different automatic garden irrigation applications.

An important exception is bubbler nozzles, which Rain Bird specifically excludes from compatibility. The extension does not provide pressure regulation or spray distance adjustment. Its purpose is to increase the installation height of a compatible spray nozzle.

Tool-free installation and UV-resistant construction

The Rain Bird 1800-EXT is manufactured from durable, UV-resistant thermoplastic for outdoor use. Installation requires no special tools. The extension is fitted to the designated spray head connection and then equipped with a compatible nozzle. This allows the spray height to be changed quickly and conveniently.

The design also allows the extension to be reinstalled if it is accidentally knocked off the sprinkler without damaging the threads. Whether you are installing a new irrigation system or adapting an existing one, the 1800-EXT is a practical solution for raising spray nozzles in planting beds and landscaped areas.
