Rain Bird US400 Spray Head
Meet your landscaping needs with the reliable and versatile Rain Bird US400 4" UNI-Spray Series Pop-Up Spray Head Sprinkler. This compact and durable 4-inch pop-up spray head body is the ideal choice for watering smaller grassy areas, flowerbeds, and shrubs, especially around sidewalks and driveways. The US400 is built for flexibility and convenience, shipping with no nozzle pre-installed (flush plug only), so you can pair it with any Rain Bird nozzle—including MPR, VAN, and U-Series—to perfectly match the specific watering needs of your landscape.
Constructed from rugged, corrosion-resistant plastic and stainless steel, the UNI-Spray is built to last. It features a pressure-activated, multi-functional wiper seal that prevents excessive flow-by, stops debris from entering the unit upon retraction, and ensures a positive pop-up every time. The durable stem ratchet allows for quick and easy nozzle pattern alignment without tools, and the internal parts are removable from the top for simple servicing.
