Hunter HE-40-B point-source drip emitter delivers consistent, low-volume irrigation where precise water placement matters. Engineered for reliable performance, this emitter maintains steady flow across typical landscape pressures and reduces waste by applying water directly to the root zone.

  • Consistent flow: 4.0 GPH (15 l/hr) pressure-compensating design maintains uniform output over varying pressures.
  • Anti-clogging: self-flushing diaphragm helps prevent debris buildup for continuous operation.
  • Easy installation: self-piercing 1/4 in barb installs into tubing without complex tools.
  • Field-friendly: coined, easy-grip edges and earth-tone tan color make handling and flow identification simple.
  • Optional diffuser cap: available to diffuse output where needed to reduce erosion or concentrate water distribution.
  • Applications: ideal for micro-irrigation zones, trees, shrubs, and targeted landscape plant watering.

This compact Hunter emitter is a practical choice for designers and homeowners seeking dependable, low-maintenance drip components that provide accurate delivery and long-term reliability when used with compatible drip tubing and filtration.
