siamese connection
A firefighter attaches a hose to the siamese connection on the building's exterior.
Noun: A siamese connection is a specialized firefighting inlet fitting. It has two or more couplings where hoses from multiple fire engines can be connected simultaneously. Its primary purpose is to allow a high volume of water to be pumped into a building's internal fire sprinkler or standpipe system.
The term is used specifically in the context of fire protection systems and firefighting operations. * Firefighters used the building's siamese connection to supply water to the upper floors. * The building code requires a siamese connection on the exterior for the fire department's use. * The siamese connection is typically painted red and marked clearly.
- The design allows multiple hoses to feed into a single inlet, increasing water pressure and volume to the building's internal fire suppression system.
- It is a critical access point for firefighters when a building's internal water supply is insufficient or needs augmentation.
- Siamese (adj): Used attributively to describe the connection. (e.g., siamese fitting, siamese inlet).
- Fire department connection (FDC): This is a more modern and commonly used technical term synonymous with "siamese connection."
- Standpipe: The internal piping system the siamese connection supplies.
- Sprinkler system: The automatic fire suppression system the siamese connection may supply.

- The name "siamese" originates from the conjoined twins Chang and Eng Bunker (1811–1874), who were from Siam (now Thailand). It is used metaphorically to describe the two (or more) inlets joined into one common outlet. In modern professional terminology, "Fire Department Connection (FDC)" is often preferred.
