Raindrip 157050B Adjustable Flow Bubbler — Full-Circle 8-Stream, 1/4-Inch Inlet, 50-Pack

Raindrip 157050B Adjustable Flow Bubbler: versatile, easy-to-tune irrigation

Designed for drip irrigation enthusiasts and backyard gardeners, the Raindrip 157050B combines a compact bubbler with a dial to control water output. It delivers a steady, full-circle spray that gently wets soil around carefully chosen plantings, making it ideal for groundcovers, decorative grasses, flower beds, vegetables, and young trees or shrubs.

How it works

The emitter is a non-pressure compensating device, so flow can vary along the line. As water travels through tubing, elevation and length influence how much spray reaches each area. The dial lets you increase or decrease flow to match your landscape's needs.

• Full-circle, 8-stream spray pattern for uniform coverage
• Adjustable discharge from 0 to 11.7 GPH
• Radius reaches up to 16 inches at 40 PSI
• 1/4-inch barbed inlet fits punched holes in standard 1/4-inch tubing

Practical use ideas

Place these bubblers along garden edges to softly water perimeters, around shrubs to keep root zones moist, or near groundcovers to encourage even growth without overspray. For vegetable beds, space emitters to match plant spacing, adjusting flow to avoid soggy spots. With a 50-pack, you can outfit multiple zones in a single project.

Durability and compatibility

Aircraft-grade construction with a low-visibility black finish blends into landscape features. The 1/4-inch barbed inlet is designed for seamless integration with standard irrigation tubing, supporting flexible layouts in complete drip systems.
