Fire Hydrants

Fight fires in areas around your facility that city-installed hydrants don’t reach. These hydrants are dry-barrel, the most common type of hydrant, which means they drain water when not in use. Not only does this prevent freezing, but it keeps water from spurting out if a vehicle hits these hydrants. And if they get hit, they won’t need much repair—their safety flange and safety stem coupling break without shattering. That means the hydrant comes off cleanly, minimizing damage to the main body and stem. To repair, just replace the flange and coupling using the repair kit (sold separately).

These hydrants must be installed and maintained according to National Fire Protection Association (NFPA) Standards. If your main line is below 5 ft., attach a stem extension (sold separately). An extension can also raise your hydrant above the ground.

These hydrants are FM approved and meet AWWA C-502 standards for the durability, reliability, and safety of dry-barrel fire hydrants. Connect them to the plain end of a water main line with their mechanical joint connection. The fitting will maintain a tight seal through normal underground movement and temperature changes.

Threaded Flow-Adjustment Valves with Fire-Fighting Hose Fittings

Connect these valves to fire hydrants, fire pumps, and fire hoses to adjust the flow of water. Ideal for fighting fires, their internal gate allows unrestricted flow when fully open, unlike globe valves. However, you should only use these valves in emergencies when full flow is needed—they get damaged by throttling over time. They have a nonrising stem that stays in the same spot whether they’re open or closed.

Wheel Handle—377 Brass Body with Brass Gate

Valves with a wheel handle take up less space than valves with a speed handle. The included hose cap protects them from dirt and debris. It’s connected to the valve with a chain, so you won’t lose it.

Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Speed Handle—Red Brass Body with Bronze Gate

Valves with a speed handle can be turned with one hand, unlike valves with a wheel handle. Quickly connect the fittings to hydrants, pumps, and hoses with the easy-to-grip pin lugs on the sides. Tighten them with a hook-style spanner wrench. To prevent kinking when you’re connecting a hose, the fittings swivel until tightened. These valves are red so people know they’re fire valves.

Plastic Threaded Flow-Adjustment Valves with Garden Hose Outlet

For a lightweight and corrosion-resistant alternative to metal, these valves are plastic. With an NPT inlet and a GHT outlet, they are often attached to garden hose. All gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. Their nonrising stem stays in the same position whether the valve is open or closed.
