2019年6月12日 · Different types of fire equipment have different thread genders Male or female threads on fire hose fittings and adapters connect to corresponding inlets or outlets on firefighting equipment. In most cases, equipment that discharges water has a male-threaded outlet—much like a garden hose—and orifices that receive water have fixed female ...

2018年6月12日 · National Hose/National Standard Thread (NH/NST) and National Pipe Straight Hose (NPSH) thread are two of the oldest and most widely-adopted thread types for fire department connections and hoses. Each connects the male end of a hose — where threads are located on the outside of the coupling — with a female FDC coupling, which has a threaded ...

The most common hose connection standard on FDC inlets is 2.5″ National Standard Thread (NST), which is sometimes also called “fire hose thread” or National Hose Thread (NH or NHT). Nevertheless, certain local jurisdictions use other sizes and connection types, including National Pipe Straight Thread (NPS) or unique regional standards.

2013年3月19日 · Storz solves a common problem faced by firefighters: mismatches between couplings. The thread types or coupling standards firefighters use to connect their hose to the standpipe, sprinkler system, or fire hydrant may vary from city to city—or, in rare cases, even from building to building. Storz connections, however, are the same everywhere.

2019年3月26日 · One of the most widely-used thread standards on a fire department connection is the 2.5″ National Standard Thread.

2019年4月5日 · Their outlets typically connect to female swivels on fire hoses, which means that they typically use either male National Standard Thread (NST) or National Pipe Straight Hose Thread (NPSH). Fire hose angle valves belong to one of two types: standard valves or pressure-restricting valves. Standard fire hose angle valves allow for complete ...
