Our QB2® Bubbler is available in four color-coded models, with flow ranges of 2, 6, 10, and 20 GPH per outlet and uses a 1/2” FPT inlet
thread base. The QB2® diaphragm is injection molded from liquid silicone rubber, which provides pressure compensation and uniform
water application. The QB2® Bubbler has 4 horizontal outlets for
easy installation of distrubution tubing. The QB2® is ideal for converting existing sprinkler systems to efficient low flow systems. It is designed to apply the desired amount of water directly to the
plants during the time the sprinkler zone operates.

Primary Application: Designed for tree, shrub, flower and ground cover planting beds. This bubbler can be placed on spray-head zones and matches sprinkler zone timing.
