Fire Hoses is a high-pressure hose that carries water or other fire retardant (such as foam) to a fire to extinguish it. Outdoors, it attaches either to a fire engine or a fire hydrant. Indoors, it can permanently attach to a building’s standpipe or plumbing system. By materials, there are PVC fire hoses, rubber fire hoses, PU firehoses. By layers, there are single lined fire hoses, double lined fre hoses. 

Hose Couplins is a connector on the end of a hose to connect (or couple) it with another hose or with a tap or a hose appliance, such as an irrigation sprinkler. By materials, there are brass or copper hose couplings, aluminum hose couplings. By styles, there are Storz hose couplings, Nakajima hose couplings, Machino hose couplings, American hose couplings, etc

Fire Nozzles is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) fire hoses. By functions, there are straight stream nozzles, jet / fog dual use nozzles. By materials, there are brass/copper nozzles and aluminum nozzles. 

Fire Hydrant is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection.
