8 and 9 outlet emitters can be used as drip emitters or as manifolds; simply connect additional tubing to the 1/4 inch barb outlets to run lines in new directions. Our multi-outlet emitters thread onto any 1/2 inch risers, allowing you to retrofit existing sprinkler systems. Our Rain Bird 8 Outlet drip emitter can be fitted with both Xeri-Bug emitters or PC modules, making this emitter highly adaptable to any drip irrigation application.
