Rain Bird US400 UNI-Spray 4 in. Pop-Up Spray Body (No Nozzle)
Rain Bird US400 UNI‑Spray is a compact, durable 4 in. pop-up spray body engineered for reliable turf and shrub irrigation. Its low-profile cover and corrosion-resistant components make it ideal for tight landscapes, walkways, and bed edges.
- Pop-up height: 4 in. (10.2 cm) for low-visibility installation.
- Overall body height: 5 7/8 in. (14.9 cm) for flush install and service access.
- Exposed diameter: 1 1/4 in. (3.2 cm) keeps the head small and unobtrusive.
- Inlet: 1/2" (15/21) NPT female threaded inlet compatible with standard fittings.
- Pressure range: 15–70 psi (1.0–4.8 bar); optimum at 30 psi (2.1 bar).
- Nozzle compatibility: Accepts all Rain Bird nozzles including MPR, VAN and U-Series.
- Durability & maintenance: Pressure-activated wiper seal, removable internals from the top, and plastic plus stainless-steel components for corrosion resistance.
The UNI‑Spray design simplifies inventory and installation by accepting a wide range of Rain Bird nozzles and accessories. Optional pre-installed Variable Arc Nozzles (VAN) and high-efficiency VAN variants are available on select models to speed installation and optimize coverage. Internals service easily from the top without digging, and the pressure-activated wiper seal reduces flow‑by and debris intrusion when retracted.
Typical uses: small turf areas, lawn edges, sidewalk buffers, flower beds and shrub zones where precise, low-profile spray coverage is needed. A three-year trade warranty covers defects in materials and workmanship per manufacturer terms.
