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

Type "F" aluminum 4 inch male camlock (Cam & Groove) coupler to 3 inch male NPT threads.

Under no circumstances should cam and groove couplings be used for compressed air or steam service!

Connections

  • The male side of this adapter will only connect to 4 inch female camlock
  • The male threaded side of this adapter will only connect to a 3 inch female National Pipe Straight Hose (NPSH) or National Pipe Tapered (NPT), for example, PVC or metal pipe fitting

How it works

  • To make a connection, simply slide the camlock adapter into the camlock coupling and with normal hand pressure, press the cam levers down.
  • Uncoupling is as quick and simple as coupling. Just lift the cam arms and remove the adapter.

Cam and groove couplings, also called camlock fittings or quick connect fittings, are used in most industries as a hose connection to avoid leakage. The cam lock type of coupling is popular because it is considered to be a simple and economical way to reconnect and disconnect.
