Rain Bird UNI-spray US-415 irrigation spray head

The Rain Bird Uni-Spray US-415 (ref. 14420) is a 4″ pop-up sprinkler body designed for residential and landscaped areas requiring uniform, quiet, low-maintenance irrigation. This version comes with a 15 ft VAN nozzle (variable arc), making it versatile for flower beds and lawns with regular or irregular shapes, with quick irrigation-sector adjustments according to the actual geometry of the area. ½" female-thread hydraulic connection.

The Uni-Spray series stands out for its pressure-activated wiper seal, which minimizes “flow-by,” prevents unnecessary water loss, and helps keep dirt from entering as the stem retracts. The stem ratchet makes it easy to align the nozzle, while the “top-serviceable” design allows internal components to be removed from the top for quick servicing. The exposed cap is small for discreet integration into the landscape, and the robust body provides durability against pressure spikes.

The US-415 operates within a typical range of 15–70 psi (optimal at around 30 psi) and, with the VAN nozzle, supports an adjustable arc from 0° to 360°. In addition, the Uni-Spray family accepts all Rain Bird nozzles (MPR, VAN, U-Series, HE-VAN…), simplifying stock management and making it easy to adapt flow rates and precipitation rates to your installation. For optimal performance, install filtration appropriate to the water quality, observe the recommended pressures, and verify adequate overlap between sprinklers to prevent dry spots or waterlogging.
