your choice of fire dept threads

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 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.

Kochek Finishes

Kochek’s hazmat adapters are furnished in Black Hard Coat Anodized Aluminum. Hard Coat is a high quality durable finish that is most often specified by manufacturing engineers. They exhibit the following qualities.

  • Meets mil spec 8625 Type III class 1
  • 2mil thickness which gives a superb abrasion and corrosion resistance that has a Rockwell C rating of 65-70 and meets ASTM B117 specification of 336+ hours of salt spray resistance.


Laser Engraving
