Rain Bird FE40-25S 4 GPH Flag Dripper | 25-Pack Emitter

Efficient root-zone watering for landscape and garden

The Rain Bird FE40-25S Drip Emitter delivers a steady 4.0 GPH flow, designed to water the root zones of garden beds, shrubs, trees, and large containers. Its non-pressure-compensating design provides predictable output within typical drip runs, while offering a quiet, steady drip around plant bases.

Key design features

• High-flow 4.0 GPH flag-style emitter with shutoff
• Non-pressure compensating construction for straightforward setup
• Dual barbed ends fit 1/2" and 1/4" drip tubing for flexible layouts
• Twist-off flag top enables fast, thorough flushing and maintenance
• Large water passages reduce clogging risk and support long life
• Durable UV- and chemical-resistant body built to withstand outdoor use

Simple installation and flexible uses

Each emitter is ready for direct insertion into mainline and lateral tubing. The barbs accept standard 1/2" and 1/4" drip tubes, allowing you to position emitters close to individual plants. For faster installation on bigger projects, pair with Rain Bird HPUN1-1S hole punch tool (sold separately).

Packaging includes 25 emitters in a convenient plastic bag, making it easy to stock up for ongoing irrigation needs. This model is available alongside other flow rates—FE10-25S (1.0 GPH) and FE20-25SX (2.0 GPH)—to tailor watering across diverse plant types and sizes.

Real-world scenarios

Imagine a row of shrubs with consistent root-zone moisture, or a collection of large planters near a walkway. The 4 GPH flow provides adequate watering for medium-sized root zones without overwatering in typical outdoor runs. The twist-off flag top supports quick clearing of debris after dusty or windy days.

• Container gardens with close plant spacing
• Shrub borders and small trees
• Mixed landscapes where near-base watering matters

Maintenance tips

Flush emitters periodically to keep passages clear and maintain steady performance. The twist-off top makes it easy to inspect and clean while the durable body withstands outdoor exposure over time.

What’s in the pack and availability

Each pack contains 25 emitters, ready for use in 1/2" main lines and 1/4" lateral tubing. The FE40-25S is part of a family that includes FE10-25S and FE20-25SX for customized irrigation plans.
