Kuriyama of America, Inc.

Shop Kuriyama fire hose, suction hose, and Viper VTE nozzles for wildland firefighting, emergency response, fire departments, contractors, forestry operations, and property-defense water systems.

This collection includes lightweight forestry hose in 3/4-inch, 1-inch, 1.5-inch, and 2.5-inch diameters, Maxiflex suction hose, and Viper VTE nozzles with NPSH and NH/NST inlet options.

Choosing Kuriyama Fire Hose

Select fire hose by intended use, inside diameter, length, coupling size, thread standard, pressure requirements, pump connection, and nozzle compatibility.

Available options include 3/4-inch GHT hose, 1-inch NPSH hose, and larger 1.5- and 2.5-inch NH hose. Length options include compact 25- and 50-foot sections as well as 100-foot hose for longer water-delivery layouts.

Review each product’s working pressure, test pressure, construction, weight, coupling material, and intended application before ordering. Hose diameter and length can affect water flow, friction loss, handling, and pump requirements.

NH, NST, and NPSH Thread Compatibility

NH and NST are commonly used names for the same fire-hose thread standard. NPSH is a different thread standard. Products with the same nominal diameter may still have incompatible threads.

Match both the hose diameter and thread designation when selecting nozzles, fittings, valves, pumps, and adapters. Never force mismatched threads together.

Suction Hose and Viper VTE Nozzles

Maxiflex suction hose is designed for pump-intake and drafting applications from appropriate non-pressurized water sources. It is different from standard discharge or attack hose. Confirm the hose diameter, coupling thread, vacuum rating, pressure rating, and pump-inlet requirements.

Viper VTE nozzles use a twisting adjustment to change the spray pattern from a straight stream to fog. WD Fire Supply offers a 1-inch NPSH model and a 1.5-inch NH/NST model. Match the nozzle inlet to the hose coupling or use a properly selected adapter.

Kuriyama Hose and Nozzle Questions

What Kuriyama products does WD Fire Supply carry?

The collection includes forestry hose, suction hose, and Viper VTE nozzles in several diameters, lengths, and thread configurations.

Are NH and NPSH hose threads interchangeable?

No. NH/NST and NPSH use different thread configurations. Match both the nominal diameter and thread designation, or use an appropriate adapter designed for the exact connection.

What is Maxiflex suction hose used for?

Maxiflex suction hose is designed for pump-intake and drafting applications. It should not be treated as ordinary discharge or attack hose. Confirm the exact product rating and pump requirements before use.

Which Viper VTE nozzle should I choose?

Choose the 1-inch NPSH nozzle for a matching 1-inch NPSH connection. Choose the 1.5-inch NH/NST nozzle for a matching 1.5-inch NH/NST connection. Confirm the exact coupling, required flow, and pump capacity before ordering.

How should I choose a fire-hose diameter and length?

Consider the pump outlet, nozzle inlet, required water flow, operating pressure, friction loss, deployment distance, hose weight, and crew handling requirements. WD Fire Supply can help confirm component compatibility.
