Aluminum 1 1/2" Dual Range 20/90 Forestry Nozzle (NH)

If you have lower water pressure or are not sure of the water pressure with which you will be using your nozzle, this is an excellent choice. A Constant Flow nozzle with too high of a GPM rate for the water pressure will not project its stream well.

The 20/90 GPM version will provide a heavier cone vs the 20/60 GPM version at max open. User must have sufficient water pressure for the 90 GPM version to project maximum stream distance. The 20/60 GPM version is better suited for average water pressures.

Crafted from anodized aircraft aluminum with large rubber bumper, this Dual Range nozzle is ultra-lightweight and extremely durable. These nozzles are designed to meet or exceed U.S. Forest Service Performance Specifications (FSS) 5100-239.

This Wildland Fire Equipment nozzle is used by the U.S. Forest Service (USFS), Bureau of Land Management (BLM), Bureau of Indian Affairs (BIA), U.S. Fish & Wildlife Service (USF&WS), National Park Service (NPS), State and Local governments, and other Forest Service–sponsored participants in the government-wide wildland firefighting effort.

This is the same water-handling accessories forestry nozzle found in the Defense Logistics Agency (DLA) Wildland Fire Equipment catalog or Fedmall.mil.

Applications

• Wildland / Forestry Firefighting
• Booster Hoses
• Sports Field Conditioning
• Golf Course Greens and Tees Watering
• Equipment and Stadium Washdowns

NH / NST: The most common thread type in use by fire departments today is NST or National Standard Thread. NST also goes by the initials NH or National Hose. It can even be referred to as NHT or National Hose Thread but NST or NH is more common these days. NH = NST.

• The female side of a NH / NST coupling will only connect to a male NH / NST connection
• The male side of a NH / NST coupling will only connect to a female NH / NST connection

NPSH: National Pipe Straight Hose (NPSH) or Iron Pipe Thread (IPT) has the same threads per inch (TPI) as National Pipe Tapered (NPT) but the thread does not taper. NPSH is a straight thread and seals by a gasket in the female coupling which allows for a swivel, just like NH / NST, which make both ideal for hose couplings.

• The female side of a NPSH coupling will only connect to a male NPT pipe or a male NPSH connection
• The male side of a NPSH coupling will only connect to a female NPSH connection.
  It will NOT thread into a female NPT pipe. For example, a male NPSH coupling will NOT thread into a female metal or pvc pipe.

NPT: National Pipe Tapered is common in plumbing and some industrial uses. Sometimes referred to as pipe thread because PVC pipe and schedule 40 pipe are typically threaded in NPT. As its name implies this is a tapered thread so that the outside diameter of the male (ODM) gets smaller towards the end of the fitting and the inside diameter of the female narrows with depth. As the two fittings are threaded together the opposite tapers force thread friction and makes the seal without the use of a gasket.
