Cold Plunge 3/4" Barbed Ozone Venturi Injector

• Efficient Ozone Injection: This PVC ozone venturi injector utilizes water flow and pressure to efficiently draw and mix ozone from ozone generator or pump into passing water through a patented venturi design.
• Proven Performance: Featuring a Mazzei-style venturi system, this injector has been delivering uniform chemical injection and years of reliable service in spa and pool circulation systems. This venturi works great at keeping your cold plunge tub, spa or pool crystal clear.
• Easy to Install: With 3/4" ribbed barb inlets and outlets and a 1/4" smooth barb for ozone line attachment, installation takes just minutes without tools on low or high-speed pumps. Works great with 3/4" flexible PVC hose. Can also be built into a cold plunge or ice bath filter assembly.
• Durable: Constructed of rigid yet flexible PVC plastic reinforced with fiber, this injector is built to last through thousands of hours of continuous chemical injection underwater.
• NOT COMPATIBLE with 1/2" plumbing reductions. Please see our InlineO3 Injector.
