Mazzei maz684k Ozone Injector 0.75 in Hose Barb 3.6G

Product Description

The MAZZEI maz684k is a venturi-style ozone injector designed for pool and water treatment systems where dissolved ozone must be introduced into a water line. Fitted with a 0.75 inch hose barb connection and rated at 3.6G ozone output, this injector draws ozone-rich gas into the water stream using differential pressure created by the flow of water through the venturi body. The red color-coding helps technicians quickly identify injector sizing in multi-injector installations. It is installed and serviced by pool service professionals and water treatment technicians.

This injector is suited for residential and light commercial pool systems and water treatment applications where ozone is used as a primary or supplemental sanitizer. The 0.75 inch hose barb fitting makes it compatible with standard flexible tubing used in pool equipment plumbing. Typical installations place the injector on the return line downstream of the pump and filter, allowing ozone to be drawn into pressurized flow before reaching the pool or treatment vessel.

Key Features

• Venturi design creates suction to draw ozone gas into the water stream without a separate pump
• 0.75 inch hose barb inlet and outlet for direct connection to flexible pool tubing
• 3.6G ozone rating indicates injector sizing for appropriate flow and vacuum performance
• Red body color-coding simplifies identification by size in multi-injector setups
• Compact form factor fits standard pool equipment pad installations

Compatibility

Designed as an OEM-style replacement or new-installation component for residential and light commercial pool ozone systems using 0.75 inch hose barb plumbing connections.

Installation Notes

Installation is typically performed by a licensed pool service technician or qualified water treatment professional. Shut off the circulation pump and relieve line pressure before cutting into the plumbing to install the injector. Ensure flow direction through the injector matches the arrow or port labeling on the body, as reverse flow will prevent ozone uptake. Verify that the ozone generator output is correctly plumbed to the suction port before returning the system to service.
