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.

Additional Details

This break apart attack nozzle is a combination of a pistol grip shut-off valve and a removable anodized aluminum dual range nozzle. This pairing of products offers simple versatility. Proven to be cost-effective and user friendly for first responders in either wildland or structure fire applications.

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.

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.

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.
