Threads

fire department thread connections

We offer many different types of thread choices to accommodate our customers throughout the USA. We maintain a card file in our office with thread types used by various cities throughout the USA.

Our standard threads are NST (NH). They will normally drop ship quicker from Kochek’s large inventory.  NSPH and NPT can also be supplied for no additional charge. If your thread type is not shown below please give us 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.
  • New York City Fire Dept (NYFD), also known as as (FDNY) is a special thread type utilized by the New York City Fire Department.
  • New York Corporation (NYCORP), also known as (NYC), (New York Corp),  is a special thread type used by a few fire departments.
