Brand: Hunter Industries SKU: PCB25 Product Overview The Hunter PCB-25 is a pressure-compensating flood bubbler that delivers a fixed flow of approximately 0.25 GPM through a 1/2-inch threaded connection. It is designed for controlled, close-in irrigation around trees, shrubs, large containers, and planting basins where a low-volume flood pattern is more useful than a spray nozzle. Pressure-compensating operation helps the bubbler maintain a more consistent discharge across normal system pressure changes and elevation differences. Its fixed quarter-gallon-per-minute flow makes zone calculations and plant-by-plant water budgeting easier than an unregulated adjustable bubbler. Key Features Fixed 0.25 GPM flow rate Pressure-compensating design Flood-style bubbler pattern 1/2-inch threaded connection Compact component for close-in watering Suitable for individual plant basins and low-volume zones Common Uses Trees and established shrubs Planting basins and large containers Low-volume irrigation near foundations or hardscape edges Replacing a matching Hunter PCB-25 bubbler Compatibility and Installation Notes Install on a compatible 1/2-inch threaded riser or fitting. Confirm that the soil and planting basin can absorb the applied flow without runoff. Use filtration appropriate for the water source and flush the lateral line before installation. This is a fixed-flow bubbler rather than an adjustable spray nozzle. Frequently Asked Questions Can the PCB25 flow be adjusted? No. It is designed to deliver a fixed pressure-compensated flow of approximately 0.25 GPM. Does it install on a spray body? The PCB-25 uses a 1/2-inch threaded connection for a compatible riser or fitting. For a female-threaded spray-body nozzle, use the appropriate Hunter PCN configuration. Why Buy the Hunter PCB25 from Big Frog Supply? The PCB25 is the lower-flow choice in this bubbler group, making it easier to water plants that need a gentler quarter-gallon-per-minute application. Big Frog Supply clearly distinguishes it from the higher-flow PCB50 and spray-body PCN nozzle.
