Mazzei - ISO 384 Series - 15mm BSPT Inlet/Outlet Connections (0.25" Barbed Suction Port Cap)
ISO 384 Series 15mm BSPT Venturi Injector
Differential pressure injector with internal mixing vanes for precise chemical dosing and air injection in water treatment systems. PVDF construction rated for demanding commercial applications.
Patented venturi design creates vacuum for chemical injection without pumps or electricity
Differential Pressure Injection
Pressurized water constricts through the injection chamber, creating a high-velocity jet stream that generates vacuum at the suction port. Draws liquid or gas additives into the flow without external power.
Internal Mixing Vanes
Patented vanes create thousands of microbubbles, dramatically increasing surface area for gas-liquid contact. Multiple small bubbles dissolve faster than one large bubble of equal volume.
PVDF Construction
Advanced thermoplastic superior to PVC and polypropylene. Resistant to ozone, sulfuric and nitric acids, chlorine, UV light, and abrasion. Higher pressure and temperature handling than standard materials.
Zero Moving Parts
Simplified maintenance with no mechanical components to wear or replace. Lower operating costs than pump-driven systems. Operates over a wide pressure range with minimal differential required.
Mazzei ISO 384 Series Connection Details
| Model Series | ISO 384 |
| Inlet Connection | 15mm BSPT Male |
| Outlet Connection | 15mm BSPT Male |
| Suction Port | 0.25" Barbed with Cap |
| Material | PVDF (Polyvinylidene Fluoride) |
| Thread Standard | British Standard Pipe Thread |
| Certifications | NSF 61 and FDA approved (Natural PVDF) |
Applications and chemical resistance
The Mazzei ISO 384 Series injector works with commercial reverse osmosis systems, irrigation water treatment, aquaculture oxygenation, ozone injection, and chemical dosing applications. PVDF material is compatible with most acids and alkalis, chlorine solutions, ozone, peroxide, and aggressive oxidizers. Not recommended for strong bases above pH 10 without testing. 15mm BSPT threads are equivalent to 0.5" Male NPT PVDF injectors in thread pitch. Actual thread diameter measures 0.825" on a ruler, not 0.5" as the nominal size suggests.
Mazzei injector construction materials
Polypropylene (PP - Green)
Versatile and cost-effective. Highly resistant to most acids and alkalis. High tensile strength, lightweight, and rigid. Best for general chemical dosing in non-ozone environments.
PVDF (Blue or Natural)
Superior pressure and temperature handling. Resistant to ozone, sulfuric and nitric acids, chlorine, and UV light. Better abrasion resistance. NSF 61 and FDA approved in natural color.
ECTFE (Clear)
Excellent alkaline resistance above pH 10. Extreme chemical resistance, low flammability, physiologically safe. Insensitive to UV-A and UV-B. For demanding tank and apparatus construction.
Wide Pressure Range
Operates efficiently across variable inlet pressures with minimal differential required to generate suction
No Maintenance
Zero moving parts means no seals, bearings, or pumps to service or replace over time
Microbubble Mixing
Internal vanes create superior gas dissolution for ozone, oxygen, and air injection applications
UV Resistant
PVDF material withstands direct sunlight and outdoor installation without degradation
