The 6-Outlet emitter is a Drip irrigation manifold that threads onto a 1/2 inch riser. This 6 Outlet Manifold provides a centralized water distribution connection for up to six emission devices. Use ¼ inch distribution tubing to attach to each of the outlets and direct the flow. Unused outlets may remain capped. The EMT-6XERI does not regulate water flow and therefore should be used with an emitter such as a button emitter, stake emitter or adjustable emitter.
