Hunter emitters apply water slowly and directly at the plant to ensure every drop is put to efficient use. They are available in three convenient styles including self-piercing barb, 10⁄32 threaded, and ½" female thread. The barb and 10⁄32 thread models are available in 0.5, 1, 2, 4, and 6 GPH models and the ½" female threaded models are available in 1 and 2 GPH. This wide range of flow rates offers you the flexibility to give individual plants and trees the right amount of water from a single emitter. They are also color-coded for fast flow identification and feature coined edges for easy gripping during installation. An optional diffuser cap is available to help gently distribute water at high GPH flow and to protect the emitter outlet from clogging. Manufactured by Hunter in the USA, these emitters offer the ability to enhance both water and operational efficiency in any micro-irrigation zone.
