Threaded Bushing
Our threaded bushings (reducing bushings) enable connection between pipes of different diameters. Featuring male external threads on the outside and female internal threads on the inside, they serve as compact adapters that save space compared to coupling-and-nipple combinations. Ideal for changing pipe sizes at equipment connections and branch lines.
