TPR400-10-1/2 | Turbo Nozzle, 5800 PSI, 1/2″ FNPT Inlet

TPR400-10-1/2 | Turbo Nozzle, 5800 PSI, 1/2″ FNPT Inlet

The Annovi Reverberi TPR400-10-1/2 Rotary Turbo Nozzle takes the high-flow performance of the TPR400-10 and packages it with a larger 1/2″ F NPT inlet, making it ideal for direct plumbing into hydro-excavation booms, lances, and industrial spray manifolds. With a 10.0 nozzle size and maximum working pressure of 5,800 PSI, this nozzle produces a powerful rotating 0° jet with a 20° cone, perfectly suited for hydro-excavation, potholing, and heavy-duty washdown where volume and impact are both critical.

Built on the same rugged TPR400 platform, the TPR400-10-1/2 features a brass body, ceramic tip, and balanced rotor engineered to withstand continuous, high-duty cycles. Rated to 212°F (100°C), it performs reliably with hot or cold water on powerful hydrovac trucks, high-flow skids, and industrial cleaning rigs.

Key Specifications

• Model: TPR400-10-1/2 Rotary Turbo Nozzle
• Nozzle Size: 10.0
• Maximum Pressure: 5,800 PSI (400 bar)
• Maximum Temperature: 212°F (100°C)
• Spray Angle: 20° rotary cone
• Inlet Connection: 1/2″ F NPT

Performance & Design Highlights

• High-flow 10.0 orifice: Optimized for big pumps and hydrovac trucks that can supply substantial GPM at elevated pressures.
• Rotating zero-degree jet: Concentrated stream spins at high RPM, delivering intense cutting energy for soil removal, scale breakup, and heavy surface cleaning.
• 1/2″ F NPT inlet: Larger thread size simplifies integration into excavation lances, boom plumbing, or high-flow manifolds without extra adapters.
• Hot-water compatible: 212°F rating supports hot-water hydro-excavation and degreasing where temperature improves efficiency.
• Heavy-duty construction: Brass housing and ceramic internals are built for long-term service in harsh, wet, and abrasive environments.

Typical Applications

• Hydro-excavation & potholing: Used on hydrovac and jet-vac trucks to fluidize soils and road base around buried utilities, poles, valve boxes, and fiber ducts while minimizing risk of mechanical damage.
• Utility daylighting: Safely exposing gas, water, sewer, and telecom infrastructure for inspection, tie-ins, and repairs.
• Slot trenching: Creating narrow trenches for pipe and cable runs where precise, non-mechanical excavation is needed.
• Industrial surface and equipment cleaning: Removing thick product buildup, scale, and residue from pads, pits, and steel structures.
• Heavy washdown: High-volume cleaning of large, contaminated surfaces in plants, yards, and transfer stations.

Sizing & Compatibility Recommendations

• Pair the 10.0 orifice only with high-GPM, high-pressure units sized to handle the load; confirm GPM and PSI against nozzle charts.
• Do not exceed 5,800 PSI or 212°F.
• The 1/2″ F NPT inlet threads directly into many hydro-excavation lances and boom heads, reducing the need for multiple adapters.
• Not suitable for delicate surfaces, residential siding, or soft landscaping.

Maintenance & Best Practices

• Flush lines frequently: Hydrovac and excavation work often carries grit—keep filters and plumbing clean to protect the ceramic orifice and rotor.
• Use controlled passes: Maintain steady movement and standoff distance when potholing to avoid over-cutting or undermining surrounding material.
• Monitor for wear: Inspect rotation, sound, and pattern regularly; replace or service at the first sign of degradation to keep digging performance predictable.
