NAFFCO Fire Hydrants are designed to comply with ANSI/AWWA C502.
Dry barrel design eliminates damage to the hydrant caused by freezing of the upper part.
NAFFCO Fire Hydrants are designed for high performance and easy to install, maintain and repair.
Excellent and proven flow characteristics.
2 x 2½” NH thread connectors for soft hose connection.
1 x 4½” NH thread pumper connection for fire trucks.
6” inlet connection complying to mechanical joint ANSI/AWWA C111/A21.11 or flange connection ASME B16.5 Class 150.
Operation threads are corrosion protected and for easy operation.
NAFFCO fire hydrants are high pressure rated to 250 psi compatible with today’s trends.
Internal epoxy paint system gives high corrosion protection to hydrants.
Advanced safety couplings and flange design reduces traffic damage to hydrant.
Main valve is easily removed from either the bonnet flange or ground line flange.

Body Material: Ductile Iron.
Nominal Pressure 250 psi., Test Pressure: 500 psi.
O-ring sealed flanges at the bonnet ground line and shoe simplify maintenance by eliminating gasket adhesion at these points, making disassembly easier. The O-rings are easier than flat gaskets to position during reassembly, and provide superior pressure handling.
Hold-down nut - features integral weather seal. Prevents unauthorized removal of hold-down nut or operating nut. Resilient wiper seal prevents water entry and protects from freezing; material resistant to sunlight deterioration. O-ring provides second level seal.
Safety flange - breaks cleanly to help prevent barrel damage, but strong enough to withstand normal handling. Allows economical repair, adding of extension section, rotation or changing of upper barrel without excavation.
Full flow openings - large, smooth radius hose and pumper openings reduce friction loss.
