The BSP Nakajima Adaptor Fire Hydrant Valve Adaptor is a corrosion-resistant brass fitting designed for high-pressure firefighting applications. Its hexagonal flange design and internal threading ensure secure connections in critical scenarios, while its brass material guarantees durability in harsh environments.
| Feature | Specification | Benefit |
|---|---|---|
| Material | Brass (CuZn12Z) | Corrosion resistance, heat resistance |
| Pressure Rating | 1.6MPa | Meets ISO 10157 firefighting standards |
| Thread Type | BSP (British Standard Pipe) | Universal compatibility with fire hoses |
| Design | Hexagonal flanged | Easy gripping and torque application |
Adjustable parameters include thread type (e.g., NPT, metric) and gasket material (e.g., EPDM, nitrile) to meet specific sealing requirements. Custom sizes or surface treatments (e.g., passivation) are available for specialized applications.
With brass’s inherent corrosion resistance, this adaptor ensures reliable performance in marine or chemical environments. Its hexagonal design simplifies installation under pressure, while the 1.6MPa rating guarantees safety in high-stress firefighting scenarios.
