Our industry is experiencing unprecedented price increases due to global raw material and supply chain shortages. We are managing through this period as best we can, and will adjust prices accordingly if the situation improves.

Lightweight 2 1/2 inch NH Female by NH Male gate valve is made from 6061-TG extruded aluminum. Offers excellent shutoff control directly off the hydrant or other water source. Unique design gates the water so that the valve body is not pressurized while the valve is closed. Non-rising spindle with full 2 1/2 inch waterway flow. Spindle crank allows for complete range from open to closed in 14 revolutions. Surface finish is a Black Hard Anodized Type Ill Class 2 process that will provide years of protection. Extruded body and design allows for easy rebuild and maintenance of internal parts. Totally machined and manufactured in the USA from domestically sourced materials.

Note - Operating a gate valve in a partially open position can cause excessive gate wear and damage seals. Intended use is to fully open or close water flow, not intended for flow throttling.

Connections

  • 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
  • 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.
  • The female side of a garden hose will only connect to a male garden hose connection.
  • The male side of a garden hose will only connect to a female garden hose connection.

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.

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.

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.
