A 1/2-inch stainless steel (SS) bush nut—commonly referred to as a reducing bush or hex bush—is a threaded pipe fitting used to connect pipes or fittings of different sizes, specifically reducing a larger female opening to a 1/2-inch female opening. It features external (male) threads on the outside and internal (female) threads on the inside, often with a hexagonal head for tightening with a wrench.
