Rain Bird SW20-30PS Drip Emitter — 2 GPH, 30-Pack

Overview

The Rain Bird SW20-30PS Drip Emitter delivers a steady 2.0 gallons per hour, engineered to compensate for pressure changes along tubing runs. This consistency helps irrigation feel reliable across garden beds, shrubs, containers, and small trees, supporting healthy root zones without overwatering or drying out at the ends of long runs. Built to withstand outdoor conditions, the emitter resists UV exposure and common irrigation chemicals, giving you durable performance season after season.

Designed for straightforward installation, this emitter features a self-piercing barb that fits directly into 1/2" or larger drip tubing or can be paired with 1/4" tubing for plant-level placement. The large water passages and a self-flushing action work together to reduce the chance of clogs, even when water is dusty or mineral-rich. The emitters come in a convenient 30-pack, letting you outfit multiple plants or larger beds with dependable flow.
