About Fire-Fighting Hose Threads

How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Fire-Fighting Hose Fittings

Connect these fittings to fire hydrants and washdown equipment. They have a hex in the middle so you can tighten with a wrench. Fittings are brass for good corrosion resistance.

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.

Pin-Lug Fire Hydrant Caps

These caps are the fastest way to access fire hydrants and washdown equipment. They have a bracket that snaps into any type of 2 1/2 size female fire hose threads. Tap on one of the pin lugs to remove quickly in an emergency—the bracket will release the hold on the threads and the cap will fall off without breaking. Tighten with a hook-style spanner wrench (sold separately). Caps are aluminum, which is lightweight with good corrosion resistance.

Diverting Valves with Fire-Fighting Hose Fittings

Valve Type: Ball
For Use With: Water
Seal Material: Buna-N Rubber

Control the flow of water in two directions from a single source—these diverting valves have two balls and handles for independent operation of each outlet. They can direct flow to one side outlet at full capacity while shutting off flow to the second side outlet, direct flow to both side outlets at reduced capacity, or shut off flow to both side outlets. Valves have a brass body for good corrosion resistance. They are for use with fire-fighting hose.

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.

Racks for Fire-Fighting Hose

(Hose Not Included)

Use these racks with foldable lightweight fire-fighting hose (also known as pin-rack hose). A pivoting mounting bracket allows racks to swing as the hose is released to prevent kinking.
