EZ-FLO Injection Couplers

EZ-FLO mainline systems are installed in a main line irrigation system using one of two different connection options (which are sold separately of the mainline systems as they must be matched to each specific pipe size and also to ensure proper flow control). These connection options are described below.

EZ Standard Coupling Connectors:

Standard Slip Coupling Connectors are available in sizes ranging from 3/4" to 2" with socket x socket connections for gluing into PVC pipe. Standard Coupling Connectors are manufactured from Schedule 40 PVC with 1/4" nylon barbed tubing connections. Standard Coupling Connections are used to connect the EZ-FLO system to the irrigation flow line before or after the valve with the 1/4" flexible tubing which is included with every EZ-FLO system.

EZ Ball Valve Coupling Connectors:

Ball Valve Coupling Connectors are available in sizes ranging from 3/4" to 4" with socket x socket connections for gluing into PVC pipe. They are manufactured from Schedule 40 PVC with 1/4" nylon barbed tubing connections. They are used to connect the EZ-FLO system to the irrigation flow line before or after the valve with the 1/4" flexible tubing provided with every EZ-FLO system. They are required for complex system designs or when the elevation of zone valves downstream from the EZ-FLO installation point are at an elevation of 10 feet (3 meters) or more above the installation point or where the user needs more control over the operation of the fertigation unit. Ball Valve Connectors provide the ability to adjust the differential pressure between the inlet and outlet connections to the irrigation flow line and can ensure that even the heaviest organic fertilizers and supplements can be pulled from the tank.
