GI bushing reducer is a galvanized iron pipe fitting used to connect pipes of different diameters, creating a secure, leak-free transition in a pipe system. Its durable, corrosion-resistant galvanized material and threaded design make it suitable for high-pressure, long-lasting applications in plumbing, water systems, and industrial uses. The reducer works by fitting into a larger pipe socket and providing an opening for a smaller pipe to be connected.
