Fire Hydrant Hose Connection (Siamese)

The Siamese Fire Department Connection is a dual-inlet hose fitting installed on the exterior of a building, allowing fire department pumper trucks to simultaneously supply water into the building's standpipe or sprinkler system through two hose lines significantly increasing the water flow rate available to the building's internal fire suppression infrastructure during a fire event. Kennedy Valve Siamese connections feature two 2½-inch swivel female inlets combining into a single outlet connection to the building's fire water main, with automatic clapper check valves in each inlet to prevent backflow when only one inlet is in use. The chrome-plated brass body and storz or threaded coupling options ensure compatibility with local fire department hose fittings. Compliant with NFPA 13, NFPA 14, and local BFP requirements, they are a mandatory component in all high-rise and commercial building fire protection installations.
