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. Show more
