Fire Department Connections (FDC's) + 4-Way Connections + Inlet Connections + Outlet Connections

Exposed Siamese Fire Department Connections

Exposed Siamese Fire Department Connections (FDC's) are generally mounted on the outside wall of a building. They are used to supply water to both standpipes and automatic sprinkler systems.

Exposed Siamese FDC's are available with either two or three inlets. The two inlet versions are available with either single or double clappers (aka check valves). The three inlet versions (triple clappers) have individual drop clappers on each inlet.Read more

Free Standing (90 Degree) Siamese Fire Department Connections

Free Standing Siamese Fire Department Connections (FDC's) serve the same purpose as exposed wall type siamese FDC's; they are used to supply water to both standpipes and automatic sprinkler systems. However, the free standing type is generally mounted to a vertical pipe protruding from the ground.

Free Standing Siamese FDC's are available with either two or three inlets. The two inlet versions are available with either single or double clappers (aka check valves). The three inlet versions (triple clappers) have individual drop clappers on each inlet.Read more

Flush Siamese Fire Department Connections

Flush Siamese Fire Department Connections (FDC's) perform the same function as both the exposed and free standing types; they allow fire departments to supply water to a building's standpipe and/or fire sprinkler system. However, because they are mounted flush with the building's wall, the body remains concealed with only the escutcheon plate and swivel connections (snoots) visible.Read more

Exposed Hydrant / Pump Test / Roof Manifold Connections

The exposed type hydrant (or pump test, or roof manifold) connection is designed as an outlet. Generally, it is mounted to the wall of a building, similar to an exposed siamese FDC. But, unlike a siamese FDC, water is expelled from the hydrant, rather than pumped into it.Read more

Free Standing (90 Degree) Hydrant / Pump Test / Roof Manifold Connections

The free standing, or 90 degree hydrant (or pump test, or roof manifold) connection is designed as an outlet. Generally, it is mounted to a pipe extending vertically from the ground, similar to a free standing siamese FDC. But, unlike a siamese FDC, water is expelled from the hydrant, rather than pumped into it.Read more

Flush Hydrant / Pump Test Connections

Flush mounted hydrants and pump test connections are designed to work as outlets, just like the exposed and free standing type. But, the body of the flush type is concealed behind a wall, with only the escutcheon plate and male connections with caps or valves left visible.Read more

Single Fire Department Connections

Single Fire Department Connections (FDC's) are generally mounted on the outside wall of a building. They are primarily designed as inlet connections to allow fire fighters to supplement the building's automatic sprinkler system. Read more

Single Wall Hydrant Connections

Single Wall Hydrant Connections are usually mounted to the outside wall of a building. Unlike the single FDC, single wall hydrant connections are designed as an outlet connection with male threads. They are usually furnished complete with Escutcheon Plate, Male Adapter, and Read more

4-Way Siamese Fire Department Connections

4-Way Siamese Fire Department Connections (FDC's) come in a variety of configurations including Flush Mount Horizontal, Flush Mount Square, Flush Mount Vertical, and Free Standing. Their design and purpose is the same as a small FDC - as an inlet connection to provide supplemental water to a standpipe or automatic sprinkler system. 4-Way FDC's are typically furnished complete with Escutcheon Plate, Clappered Snoots, and Read more

4-Way Hydrant / Pump Test Connection

4-Way Hydrants and Pump Test Connections come in a variety of configurations including Flush Mount Horizontal, Flush Mount Square, and Flush Mount Vertical, and Free Standing. They are designed as outlet connections, identical to the smaller hydrant and pump test connections. However, unlike the smaller connections, the larger 4-Ways are typically furnished complete with Escutcheon Plate, Read more
