Description

Dual Range Nozzles perform over a wider range of water pressures than constant flow nozzles and give the operator more GPM control with both a low flow and a high flow rate. This aluminum twist nozzle initially opens to the lower GPM range straight stream pattern, then the low range fog pattern, then high GPM straight stream and finally high GPM fog pattern. Simply twist the barrel to adjust the patterns and to turn on/off.

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.

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.

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.
