About Brass Fire Hose Adapter Male X Male - 2 1/2" NH To
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. 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. 2" Male Adapter Inside diameter of a male adapter - 2 inch Outside diameter of a male NH / NST adapter - 2.51 inches (8 Threads per inch) Outside diameter a male NPSH or NPT adapter - 2.35 inches (11.5 Threads per inch) Note - 2 inch NH or NST is very rare.
