The QuadraBubbler® is our original four-outlet, pressure compensating, low-flow irrigation device. Available in four colorcoded models, with GPH flow ranging between 2, 6, 10 and 20, per outlet. It uses a 3/4” MPT inlet thread base. The diaphragm is injection-molded from liquid silicone rubber, which provides pressure compensation and uniform water application. The QuadraBubbler® is ideal for converting sprinkler systems to low flow because it is designed to apply the amount of water the plants need during the time the sprinkler zone operates.

Primary Application: Designed for tree, shrub, flower and ground
cover planting beds. Also, this bubbler is designed to replace sprayhead zones.
Water is applied in the right quantity where you need it without waste.
The pressure compensating diaphragm will deliver controlled distribution of water across a wide pressure range from 20 PSI to 60 PSI.
Four color-coded models available to identify outlet flow rates.
Blue: 2 GPH; Black: 4 GPH; Red: 10 GPH; Green: 20 GPH. Flow
rates are per outlet.
Each bubbler has 4 outlet ports; each outlet will deliver the flow rate as stated; total flow equals the stated flow times 4 outlets.
Uses .170 I.D. tubing. PE QuadraBubbler® tubing is recommended. Clamp plates included.
Requires a 150-mesh screen filter.
The QuadraBubbler® has a 3/4” MPT inlet base for connection to the lateral line.
QuadraBubblers® can be added to a turf spray zone for planting beds without affecting the zone timing.
Constructed of UV sunlight-resistant, chemical-resistant, non-corrosive material.
