Fire-Fighting Hose Fittings
Connect these fittings to fire hydrants and washdown equipment. Made of brass, they have good corrosion resistance. Some have a hex in the middle so you can tighten them with a wrench.
NH/NST (National Hose/National Standard) threads are only compatible with other NH/NST threads. BIT (British Instantaneous Thread) threads are commonly used in the United Kingdom, Ireland, India, Hong Kong, and parts of Canada. They’re also known as John Morris couplings.

Rocker-Lug Fire-Fighting Hose Fittings
The rocker lugs on these fittings allow for easy gripping, so you can quickly connect to fire hydrants and washdown equipment. Tighten with a hook-style spanner wrench (sold separately).
Fittings that swivel until tightened rotate to help prevent kinking during installation.
NH/NST (National Hose/National Standard) threads are only compatible with other NH/NST threads. Male NPSH (National Pipe Straight Hose) threads are compatible with female NPSH threads. Female NPSH threads are compatible with male NPSH, NPT, NPTF, and NPSM threads.
Aluminum fittings are more lightweight than brass fittings. They have good abrasion and corrosion resistance. Brass fittings are softer than aluminum fittings, so they’re easier to thread together. They have good corrosion resistance.

Pin-Lug Fire-Fighting Hose Fittings
The pin lugs on these fittings allow for easy gripping, so you can quickly connect to fire hydrants and washdown equipment. Tighten with a hook-style spanner wrench (sold separately). All are brass for good corrosion resistance.
Fittings that swivel until tightened rotate to help prevent kinking during installation.
NH/NST (National Hose/National Standard) threads are only compatible with other NH/NST threads.

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.
