We offer many different 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. If your thread type is not shown below, please call us to discuss your requirements. We want to be your adapter supplier and stand ready to meet your custom 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 Thread Taper (NPT) is a U.S. standard for tapered threads used on threaded pipes and fittings.

  • 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.

  • Garden Hose Thread" (GHT) is a U.S. standard for 3/4" diameter straight (non-tapered) thread with a pitch of 11.5 TPI (male part has an outer diameter of 1 116 inches.
