Elkhart offers a wide variety of discharge sizes to suit any need. Additionally, Elkhart’s stacked tips allow you to customize the smooth bore to meet your needs in the field.

Thread Types
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 makes both ideal for hose couplings.
