1. Product Overview
The HAGO 3.75 GPH 45 Degree P Solid Nozzle is engineered for applications requiring a precise, solid cone spray pattern. This durable nozzle is designed for consistent performance and efficient fluid delivery.

This image displays the HAGO 3.75 GPH 45 Degree P Solid Nozzle. The main component is a metallic nozzle with '3.75' and '45' etched on its side, indicating its flow rate and spray angle. A fine mesh filter is visible at the threaded end. Alongside the nozzle, there is a clear, rectangular plastic protective case. Also present is a green hexagonal piece, likely an identification tag, with 'Hago', '3.75', and '45°P' printed in white.
Components:
- Solid Nozzle: The primary component responsible for fluid atomization and spray pattern formation.
- Protective Case: A clear plastic case designed to protect the nozzle during storage and transport.
- Identification Tag: A green hexagonal tag indicating the brand (Hago), flow rate (3.75), and spray angle (45°P).
2. Setup and Installation
Proper installation is crucial for optimal performance and safety. Always ensure the system is depressurized before beginning installation.
- System Preparation: Ensure the fluid system is clean and free of debris that could clog the nozzle. Flush the lines if necessary.
- Nozzle Placement: Identify the correct location for the nozzle within your system.
- Thread Engagement: Carefully thread the nozzle into the receiving port. Ensure it is aligned correctly to prevent cross-threading.
- Tightening: Hand-tighten the nozzle until snug. Use an appropriate wrench for a final quarter to half turn, ensuring a secure, leak-free seal. Do not overtighten, as this can damage the nozzle or the port.
- Leak Check: After installation, slowly pressurize the system and check for any leaks around the nozzle connection. Tighten slightly if necessary.
3. Operating Instructions
The HAGO 3.75 GPH 45 Degree P Solid Nozzle is designed to produce a consistent solid cone spray pattern at its rated flow and pressure.
- Fluid Compatibility: Ensure the fluid being sprayed is compatible with the nozzle's materials to prevent corrosion or degradation.
- Operating Pressure: Operate the nozzle within the recommended pressure range for your system to achieve the specified flow rate (3.75 GPH) and 45-degree solid spray pattern. Consult your system's specifications for optimal pressure settings.
- Monitoring: Periodically observe the spray pattern during operation to ensure it remains consistent and free of irregularities, which may indicate a partial clog or wear.
4. Maintenance
Regular maintenance extends the life of your nozzle and ensures continued optimal performance.
- Cleaning: If the nozzle becomes clogged or the spray pattern is irregular, remove it from the system. Clean the nozzle orifice and internal passages using a soft brush and a suitable cleaning solution. Avoid using metal objects or abrasive materials that could damage the orifice.
- Inspection: Periodically inspect the nozzle for signs of wear, corrosion, or damage. Pay close attention to the orifice and the threaded connections.
- Storage: When not in use, store the nozzle in its protective case in a clean, dry environment to prevent damage and contamination.
5. Troubleshooting
If you encounter issues with your nozzle, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced flow or no spray | Clogged orifice or internal passages. | Remove and clean the nozzle. Check for debris in the fluid system. |
| Irregular or distorted spray pattern | Partially clogged orifice, damaged orifice, or incorrect operating pressure. | Clean the nozzle. Inspect the orifice for damage; replace if necessary. Verify system pressure. |
| Leakage at connection point | Loose connection, damaged threads, or missing/damaged seal. | Ensure the nozzle is properly tightened. Inspect threads for damage. Check for presence and condition of any required seals or gaskets. |
