These cylindrical reducing couplings connect two pipes of different diameters, making it easy to add height or length to table legs, bar stools, clothing racks, and more. Made from durable, industrial-grade malleable iron, these fittings are 100% authentic and built to last. PIPE DECOR parts are recognized for their combination of strength and style—real industrial fittings for your designs. Extra pieces and accessories are available for custom projects, allowing plug-and-play as desired. Perfect for any DIY project, these iron fittings suit a variety of aesthetics, including steampunk lighting, industrial, factory, French country farmhouse, vintage, retro, reclamation, DIY customized, and modern designs. We recommend cleaning and sealing each fitting before use. IPS threads ensure compatibility with other project materials, such as lamp parts and valves, and they work seamlessly with any pipes, fittings, or PIPE DECOR furniture kits.
