Complete Venturi Fertigation Kits for Drip Irrigation Systems
The 1/2″ Mazzei Injector Kit is a ready-to-install fertigation solution for gardens, farms, and commercial irrigation systems. Each kit pairs a commercial-grade Mazzei venturi injector with an F-30 L liquid flowmeter (rated 5–40 GPH) and a complete K-184 suction line assembly — so everything you need to start injecting liquid fertilizer or chemicals into your drip irrigation system arrives in one package.
Mazzei venturi injectors work purely on differential pressure — no moving parts, no motor, no electricity. Water flowing through the injector body creates a pressure drop that draws liquid concentrate from a separate container directly into your mainline. Once dialed in, they deliver consistent, reliable fertigation cycle after cycle. Rebuild kits are available if service is ever needed. Important: Select the kit that matches your system’s flow rate (GPH). An oversized injector will not draw solution; an undersized one will restrict flow.
Choose the flow-rate option that matches your irrigation system. All three kits include the same suction line assembly and flowmeter — only the injector model differs.
