A left-right black malleable iron coupling is designed to join two sections of pipe with threads running in opposite directions. This allows the pipes to be screwed together tightly without turning the entire pipe section, making it ideal for applications in gas, water, steam, and air lines due to its strength and durability. Made from durable, industrial-grade malleable iron, our fittings are 100% authentic and built to stand the test of time. PIPE DECOR® parts and accessories are instantly recognizable, combining beauty and strength—real industrial fittings for your decorations and designs. Extra pieces and accessories are available for custom projects and expansions, allowing for easy plug-and-play use. Please note: Pipe needed to thread into the left side of the coupling is not available on pipe-decor.com. All nipples and pipes sold on our website are right-threaded only. These iron fittings complement a wide range of aesthetics, including steampunk lighting, industrial, factory, French country farmhouse, vintage, retro, reclamation, DIY customized, modern, and more. We recommend cleaning and sealing each fitting before use to ensure quality and longevity. IPS threads provide compatibility with other project materials such as lamp parts, valves, and more, offering a versatile solution for many applications.
