Reliable, low-volume irrigation from a pressure-compensating flood bubbler designed for uniform distribution across a broad pressure range. Available in two flow options (0.50 and 0.25 GPM) and sized for a 1/2 in. NPT inlet, this Toro bubbler helps deliver consistent output between 20 and 75 PSI. Ideal where gentle, even water application is needed for bed, border, shrub and tree irrigation.

  • Pressure-compensating performance: Maintains consistent flow from 20–75 PSI to reduce dry/wet spots and deliver even coverage across the wetted area.
  • Selectable flow rates: Choose 0.50 GPM (TFB50PC) or 0.25 GPM (TFB25PC) to match plant water needs and system design.
  • Standard 1/2 in. NPT connection: Installs directly into standard 1/2 in. female fittings or adaptors for quick integration with common irrigation piping.
  • Application flexibility: Suitable for shallow flooding, root-zone watering, shrub and tree rings, and other low-profile irrigation applications where uniform application is required.
  • Simple maintenance: Periodically flush the line and inspect for debris; easy access and straightforward replacement when needed.
  • Compact design: Low-profile nozzle reduces spray drift and focuses distribution for efficient water use and reduced runoff.

For detailed specifications and installation guidance, refer to the manufacturer catalog page linked on the product listing. Choose the flow variant that matches your irrigation plan and consult system pressure at the point of installation to ensure optimal performance.
