Raindrip 156005B Adjustable Flow Bubbler — 8-Stream Full-Circle Drip Emitter, 5-Pack, 1/4-Inch Barbed Inlet

Precision irrigation with flexible control

The Raindrip 156005B Adjustable Flow Bubbler puts you in charge of how much water reaches the root zone. The head acts as a dial, allowing a flow range from 0 to 11.7 GPH. Paired with an 8-stream emitter, water is distributed in a full-circle spray, delivering even coverage that suits diverse plantings without flooding surrounding soil.

Built for outdoors, the emitter sits on a 5-inch stake to keep it steady as you position it for best root-zone watering. A built-in 1/4-inch barbed inlet connects to standard 1/4-inch supply tubing, making it easy to slide into existing drip lines. The body is made from UV-inhibited polyethylene, designed to stand up to sun, heat, and routine irrigation cycles.

Ideal for a wide range of plantings

Great for groundcovers, ornamental grasses, flower beds, vegetable plots, and even trees and shrubs. The adjustable flow helps you tailor watering to different plant types and densities, while the fixed stake helps you maintain even moisture at the root zone—where it matters most.
