The Rain Bird 1402 is a pressure-compensating, full-circle bubbler engineered for dependable low-flow irrigation of trees, flower beds and shrub areas. It delivers a steady 0.50 GPM output and maintains uniform flow across a wide pressure range so water is applied gently and consistently where plants need it most.

  • Flow rate: 0.50 GPM (0.11 m³/h).
  • Pattern: Full-circle, trickle pattern for gentle umbrella coverage.
  • Pressure range: Maintains consistent flow between 20–90 psi (1.4–6.2 bar).
  • Coverage: Effective radius of 1 to 3 ft (0.3–0.9 m) when mounted on a ½" male riser.
  • Connection & filter: ½" (15/21) female threaded inlet; shipped with SR‑050 ½" bubbler filter screen to resist debris.
  • Construction: Corrosion-resistant plastic with stainless steel components for long service life.
  • Dimensions & warranty: Height 1" (2.5 cm), top diameter 1" (2.5 cm); backed by Rain Bird trade warranty.

Designers will appreciate the compact footprint and reliable pressure compensation that reduce runoff and improve irrigation uniformity in landscaped beds and around individual specimens. For complete performance tables, installation drawings and CAD files, see the Rain Bird 1300A‑F and 1400 Series technical specification literature available from the manufacturer.

Maintenance is straightforward: periodically inspect the SR‑050 inlet screen and flush debris as needed; use recommended filtration upstream to extend service life. Compatible with 1800/RD1800 PRS spray bodies and adapters when a different mounting option is required.
