UPVC Reducer Coupler

The UPVC Reducer Coupler is a pipe fitting designed to connect two UPVC pipes of different diameters in a straight line, enabling smooth transitions in flow systems. With socket ends on both sides for solvent welding, it is ideal for use in plumbing, irrigation, water treatment, and chemical processing applications. Made from high-quality Unplasticized Polyvinyl Chloride (UPVC), this coupler ensures durability, corrosion resistance, and long-term reliability.
