The Hunter HEB-40 is a pressure-compensating point-source drip emitter designed to deliver a steady 4 GPH flow directly to the plant root zone. Built for reliable, low-profile irrigation, this emitter minimizes waste by releasing water slowly and consistently so each plant receives uniform moisture whether laid out in a garden bed, container, or landscaped area.

  • Pressure-compensating design maintains consistent flow despite pressure fluctuations, improving uniformity across long runs.
  • Three inlet variations — 1/4 in. barb, 10-32 thread, and 1/2 in. FPT — allow secure connections for a wide range of tubing and systems.
  • Durable construction resists routine outdoor wear and handling for season-after-season performance.
  • Coined edges on the body provide a positive grip for quick installation and removal without slipping.
  • Self-piercing barb option simplifies installation into soft tubing where a barbed connection is preferred.

Ideal for targeted root-zone irrigation, the HEB-40 helps reduce runoff and evaporation by putting water exactly where plants need it. Use it for individual shrubs, trees, container groupings, or specialty plantings. For best results, flush supply lines before installation and follow local guidelines for winterizing to extend emitter life.
