Product description


Brass Hydrant Adapter with Pin Lug 2-1/2" NST (NH) Female x2" NPT Male. Female to male adapters are used to bridge male tofemale hoses, pipes or valve fittings.

NH / NST: The most common thread type in use by fire departmentstoday is NST or National Standard Thread. NST also goes by the initials NH orNational Hose. It can even be referred to as NHT or National Hose Thread butNST or NH is more common these days. NH = NST.

NPSH:National Pipe Straight Hose (NPSH) or Iron Pipe Thread (IPT) has the samethreads per inch (TPI) as National Pipe Tapered (NPT) but the thread does nottaper. NPSH is a straight thread and seals by a gasket in the female couplingwhich allows for a swivel, just like NH / NST, which make both ideal for hosecouplings. Warning - It will NOT thread into a female NPT pipe. For example, amale NPSH coupling will NOT thread into a female metal or pvc pipe.
