The Toro 89-1806 SB-90 Stream Bubbler Nozzle delivers targeted, low-radius watering for non-turf areas. Designed for shrub beds, groundcover and tree rings, this low-profile bubbler soaks soil at ground level without overspray, giving plants the deep, efficient irrigation they need in tight spaces.

  • Coverage: 2' radius with a 90° arc for precise watering of small planting areas.
  • Design: Stream bubbler pattern provides a steady, low-profile flow that soaks soil rather than spraying across surfaces.
  • Pressure & Flow: Operates at 10–60 PSI; typical flow range is approximately 0.49–2.02 GPM depending on system pressure and conditions.
  • Compatibility: Fits Toro spray bodies, shrub adapters, risers and riser extenders for straightforward replacement and installation.
  • Durability: Constructed for irrigation use with corrosion-resistant materials and a clog-resistant stream profile for consistent performance.
  • Best Use: Ideal for planting beds, tree rings, ornamental landscapes and other non-turf settings where low-radius, deep soaking is required.

Routine flushing and occasional inspection will help maintain consistent stream shape and flow. Sold individually — confirm part number 89-1806 when ordering replacements. For installation, press-fit into compatible Toro bodies or attach to approved risers; always follow local codes for backflow prevention and system commissioning. See product literature and the Stream Spray Nozzles catalog page for full specifications and accessory recommendations.
