The UL FM Fireriser Wet Barrel Fire Hydrant 250PSI is designed for above-ground fire protection systems in warm or non-freezing climates. As a wet barrel hydrant, the body and outlets remain pressurized with water, allowing each nozzle valve to be operated independently for quick connection of fire hoses and monitors.
The hydrant complies with AWWA C503 and offers one pumper nozzle (4.5–4NH or 4–4NH threaded) plus two hose nozzles (2.5–7.5NH threaded). The quantities and types of pumper and hose nozzles can be selected to match local fire department requirements. Internal and external polyester coating in RAL3002 provides long-term corrosion protection and a durable red finish.
The inlet flange is drilled to ANSI B16.1 Class 125 and EN1092-2 PN16, making it compatible with common international flange standards. A monitor flange style is also available for mounting fire water monitors directly on top of the hydrant.
With a working pressure of 250 psi and temperature range from –10°C to 120°C, this UL Listed and FM Approved wet barrel fire hydrant is a dependable choice for city mains, industrial plants, terminals and tank farms supplied by a professional China manufacturer.
