Merchant couplings are machined from rolled steel, making them the only fittings we offer that are crafted from the same industrial steel as our pipes. Built to the same specifications as all our other fittings, they offer the added strength and durability of steel. Hydrostatically tested, these galvanized merchant couplings are ideal for both decorative and plumbing applications that meet local codes. Each coupling joins two pipes of the same diameter, providing a strong, sturdy extension. Their silver, shiny finish adds a clean, polished look to your pipe furniture. Fittings are 100% authentic and built to last—beauty and strength combined. Extra pieces and accessories are available for custom projects and expansions, allowing you to plug and play as needed. Galvanized pipe fittings are corrosion-resistant, perfect for creating DIY furniture without worrying about rust. They are project-ready, requiring no cleaning or sealing before use. These fittings complement a variety of styles, including steampunk lighting, industrial, factory, French country farmhouse, vintage, retro, reclamation, DIY customized, modern, and more. 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 of the same diameter.
