NH Couplings (National Hose Thread) are threaded fire hose fittings commonly used in the U.S. firefighting systems, also referred to as NST (National Standard Thread). These couplings feature standardized thread patterns for fast, secure, and leak-proof connections to hoses, nozzles, hydrants, or fire protection devices. Creative offers NH couplings in various materials such as aluminum, brass, and stainless steel, in multiple sizes, ideal for municipal, industrial, and agricultural applications.
