With 3/4" ribbed barb inlets/outlets and a 1/4" ozone port, it offers quick, tool-free installation. Its automatic shutoff enhances safety by stopping ozone flow when water circulation ceases. Constructed from durable fiber-reinforced PVC, this injector is built for long-lasting, chemical-resistant underwater use. ## Description Keep your cold plunge, ice bath, spa, or pool water clear and fresh with this high-performance Ozone Venturi Injector. Designed with a Mazzei-style venturi system, it uses water flow and pressure to efficiently draw and mix ozone from a generator or pump into the passing water. The result is consistent water treatment that helps maintain crystal clarity, reduce contaminants, and improve overall system hygiene. Built for versatility, this injector features 3/4" ribbed barb inlets/outlets to fit flexible PVC hose and a 1/4" smooth barb connection for your ozone line. Installation is quick and tool-free, making it easy to add to existing circulation systems or integrate into a new cold plunge or ice bath filter setup. An automatic shutoff feature stops ozone injection whenever water flow stops, preventing chemical release during downtime for enhanced safety and cost efficiency. Constructed from fiber-reinforced PVC, this durable venturi injector withstands thousands of hours of continuous use and is equally effective in cold plunge filtration, spa or pool circulation, and irrigation or fertigation applications. Whether you’re upgrading a home cold plunge system or optimizing a commercial spa or pool, this ozone venturi injector delivers proven performance and long-lasting reliability.

Review: Easy to install ozone venturi - I bought this venturi with the Plunge Crafter ozone unit and water filter for my cold plunge setup, and it's worked out great.
