Our standard threads are NST (NH). They will typically drop ship quicker from Kochek’s vast inventory.  NSPH can also be supplied for no additional charge. FDNY (New York City FD ) and NYCORP (New York Corporation) is available for an additional fee. If your thread type is not shown below, please give us a call to discuss your requirements. 

  • National Standard Thread (NST), also known as National Hose thread (NH). It is the most common type of fire hose coupling used in the United States.
  • National Pipe Straight Hose (NPSH), also known as Iron Pipe Thread (IPT).  It has the same TPI as 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.
