Rain Bird Drip Irrigation Spot Watering Dripper/Emitter with Diffuser Cap, 5.0 Gallon Per Hour, 5-Pack. This robust pressure-compensating emitter provides a high 5.0 gallon-per-hour flow rate. Ideal for watering root zones of large landscape plants, shrubs, bushes, small trees and large-size containers. Rain Bird's pressure-compensating design ensures all plants receive the desired watering rate regardless of their position along the distribution tubing run. Uniform flow is delivered throughout a wide pressure range from 15 to 50 PSI. Barbed ends securely retain 1⁄4" Drip tubing for a leak-proof connection. Self-piercing barb allows for direct insertion into the side of 1/2" or larger drip irrigation tubing, or in-line use with 1/4" tubing for positioning near individual plants. Designed with large water passages to help prevent clogging. Constructed of highly durable UV and chemical-resistant materials to withstand adverse conditions. Rain Bird emitters are color coded to easily identify flow rate. In most applications, this emitter's high flow rate will require installation (easy push-on) of an included diffuser cap. Bag contains (5) light brown-colored emitters with diffuser caps. Rain Bird "The Intelligent Use of Water"
