The Hunter PCB pressure-compensating bubbler delivers reliable, constant flow for deep-root watering of trees, shrubs, and planted beds. Available in four color-coded flow models, each PCB maintains its rated output across varying system pressures so you can apply water precisely where it’s needed.

  • Consistent output: Pressure-compensating design maintains rated flow across 15–70 PSI for uniform watering and reduced runoff.
  • Model options: PCB-25 (0.25 GPM, trickle), PCB-50 (0.50 GPM, trickle), PCB-10 (1.0 GPM, umbrella), PCB-20 (2.0 GPM, umbrella).
  • Easy installation: 1/2" female thread for direct attachment to 1/2" risers; simple retrofit for existing systems.
  • Durable construction: Designed for long-term landscape use; made in the USA and backed by a two-year limited warranty (see manufacturer specs).
  • Ideal applications: Best for tree and large shrub establishment and other deep-root watering needs; typical spacing 0.3–0.9 m (1–3 ft).

Choose the PCB model that matches each plant’s water requirements and rely on pressure-compensating performance to deliver even, efficient irrigation. For pop-up installations consider Hunter PCN or MSBN bubbler nozzles; for threaded riser installations use PCB models.

Frequently Asked Questions

What pressure range do these PCB bubblers operate in?
PCB bubblers maintain rated flow across approximately 15–70 PSI (100–480 kPa), ensuring consistent output under varying pressures.
Which PCB model should I choose for trees or shrubs?
Use higher flow PCB models for larger root zones: PCB-25/50 for small shrubs, PCB-10/20 for larger trees and deep-root watering.
How do I install a PCB bubbler on my system?
Screw the PCB onto a 1/2" riser or adapter. Hand-tighten and test for leaks; typical spacing is 0.3–0.9 m (1–3 ft).
Is there a warranty and where are these made?
Hunter PCB bubblers are made in the USA and are covered by a two-year limited manufacturer warranty; see spec sheet for details.
