Product Formation
* Siamese connection is use for fire fighting in water-supply service indoor or outdoor areas both .The connection one size fit with the pipe and one side connected to the hose with couling then fiting with the nozzles. When in use,open the valve and transfer water to the nozzle to extinguish the fire. The siamese connection are made by brass and iron, with smooth appearance and high tensile strength.
* Siamese connection is a water supply facility connected with fire-fighting system network inside the building. It is a instantaneous coupling,it can be efficiently and quickly connected to the valve,thereby providing water.It can be installed on ships,gardens,and ports.
* The Y Siamese water divider is a specific type of Siamese connection that is designed to split the water flow evenly between the two connected hoses. It ensures that the water pressure remains balanced, allowing firefighters to efficiently distribute water to multiple lines or attack points. The Y-shaped design of the water divider helps to minimize pressure loss and maximize the firefighting capabilities of the connected hoses.

Product Features
1.Durable Brass Build: Brass material offers strong corrosion resistance against moisture/impurities, ensuring long service life and leak-free performance in outdoor/harsh environments.
2. Multi-Source Confluence: 2-inlet & 1-outlet design merges water from two sources (e.g., fire trucks, hydrants) to boost pressure/flow, solving low-supply issues for high-rise fires.
3. Universal Compatibility: Fits standard fire interfaces (Storz, BS), enabling tool-free quick connection to most fire trucks/hydrants—no extra adapters needed.
4. Stable Sealing: Precision-machined brass ports ensure tight sealing under 1.0-2.5MPa fire system pressure, avoiding water leakage and pressure loss.
