A filler neck is a precision-engineered component that provides a controlled access point for adding coolant or other fluids to industrial reservoirs and tanks.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Port Size | Commonly 1/2", 3/4", 1" NPT or metric equivalents (e.g., M22x1.5) | |
| Seal Type | O-ring, Gasket, Thread sealant | |
| Neck Length | Varies based on tank wall thickness and installation depth | |
| Connection Type | Threaded (e.g., NPT, BSP), Flanged, Quick-connect | |
| Pressure Rating | Typically 0-50 psi (0-3.5 bar) for vented systems | |
| Temperature Range | -40°C to +120°C (material dependent) |

Its primary purpose is to provide a secure, sealed, and controlled access point for adding or replenishing coolant fluid to the system while preventing leaks, contamination, and spillage during operation and maintenance.
Selection is based on chemical compatibility with your specific coolant type (check manufacturer charts), required temperature and pressure ratings, mechanical strength needs, and environmental exposure (e.g., UV, chemicals). Common choices are plastics like PP for general use or stainless steel for harsh environments.
Yes. A cracked neck, stripped threads, or failed seal can lead to coolant leaks, resulting in system overheating, loss of lubrication, environmental contamination, and potentially catastrophic machinery failure due to insufficient cooling.
