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

Our 3 inch single jacket lay-flat mill hose is excellent for light industrial and construction applications where medium water pressure is used. This hose is constructed of an SBR synthetic rubber tube and a single layer of 100% polyester woven jackets.

Not intended for structural firefighting. Single jacket hoses are never used in the fire service.

How To Purchase Fire Hose

  • Adding color impregnation improves durability compared to untreated white hose
  • 50 foot lengths are easier to handle and offer more layout flexibility vs. 100 foot lengths
  • The most common hose, thread and couplings in use by fire departments today is double jacket hose with aluminum NH / NST
  • Double jacket hose with any color is the most durable hose available

Applications

  • Construction Sites
  • Residential Use
  • Light Industrial Use

Test Ratings (Water Only With Expansion Ring Couplings)

  • Service Pressure (A 3-minute hydrostatic test conducted by users on in-service hose to determine suitability for continued service)
  • Proof Test Pressure (A pressure equal to a least two times the service test pressure)
