For maximum reach, smooth bore tips create concentrated water flow for use with either handlines or monitors while using lower pressures of 50 or 80 psi. 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 allowsfor a swivel, just like NH/NST, which makes both ideal for hose couplings.
