Mazzei - 384 Series - 0.50" Male NPT Inlet/Outlet Connections (0.25" Barbed Suction Port Cap)

The Mazzei 384 Series venturi injector uses differential pressure and precision engineering to create vacuum suction for chemical or gas injection without moving parts. This 0.50" NPT model with PVDF construction delivers reliable mixing performance across a wide pressure range with minimal maintenance requirements.
SPECIFICATIONS

Mazzei 384 Series Technical Details

Model Series Mazzei 384
Inlet/Outlet Connection 0.50" Male NPT (both sides)
Suction Port 0.25" Barbed with Cap
Material PVDF (Polyvinylidene Fluoride)
Operating Principle Venturi differential pressure with internal mixing vanes
Moving Parts None
Compliance NSF 61 and FDA approved (Natural PVDF)
UV Resistance Yes, suitable for outdoor installation
INSTALLATION & USE

Setup and Operation

  1. Thread the 0.50" male NPT inlet connection into your pressurized water supply line using appropriate thread sealant rated for your application
  2. Connect the outlet side to your downstream piping, ensuring a minimal pressure differential exists between inlet and outlet to initiate vacuum at the suction port
  3. Attach chemical or gas supply tubing to the 0.25" barbed suction port, removing the cap and confirming a secure fit to prevent air leaks
  4. Verify that inlet pressure is sufficient to create the venturi effect—the internal mixing vanes will generate microbubbles and thoroughly mix the additive into the water stream
  5. Monitor suction rates during initial operation and adjust upstream pressure if needed to optimize injector performance
COMPATIBILITY

Material and Application Range

The PVDF construction of the Mazzei 384 series offers superior chemical resistance compared to polypropylene or PVC, including tolerance for ozone, sulfuric and nitric acids, chlorine, and elevated temperatures. This injector works with liquid or gaseous additives including fertilizers, acids, chlorine, ozone, oxygen, and other chemicals used in water treatment, agriculture, aquaculture, and industrial processes. PVDF's UV resistance and durability make it suitable for both indoor and outdoor installations where exposure to sunlight is a concern. The 0.50" NPT threading integrates with standard pipe fittings and the 0.25" barbed suction port accepts common chemical feed tubing.

🔧 Pro Tip: Use Teflon tape or paste rated for chemical service on the NPT threads rather than standard plumber's tape—PVDF connections can leak under high differential pressure if thread sealant isn't compatible with your injected chemicals.
