Above Ground Fire Hydrants
An above ground fire hydrant is an outdoor outlet connected to the buried fire water network, where firefighters and site teams connect hoses to draw water. The body stands above grade and the valve is operated from the top bonnet.
The store range has DN100 PN16 flanged hydrants in 130, 170, 215 and 245 cm lengths, plus a DN100 PN16 hydrant elbow for the network connection. The length is chosen by the burial depth of the network pipe.
Main Applications
- Industrial site hydrant networks
- Housing estate and campus fire mains
- Around warehouses and logistics areas
- Car parks and open storage yards
- Municipal and industrial zone connections

Which material? The hydrant length is chosen by the burial depth between the top of the network pipe and grade; in areas with freezing risk a self-draining body is recommended.
