Take your industrial style to the next level with Noir by PIPE DECOR. These prefinished matte black iron fittings truly stand out, lending a sophisticated vibe to any PIPE DECOR piece. A union is a three-piece, octagonal-shaped fitting used to join two pipes together, similar to a coupling. The union enables sophisticated pipe designs, such as creating a perfect loop, as seen in our Loop coffee table—without it, fully connecting a loop of pipe would be impossible. Combine any of our fitting finishes for a one-of-a-kind project that’s unique to you. The beauty of Noir goes below the surface—unlike electroplated or painted items, our finishing process causes the matte black color to permeate each fitting for a deep, lasting tone, so you never have to worry about chips or scratches. While standard black pipes and fittings are coated in protective oil during transit, Noir comes completely ready to use with no cleaning or sealing required. It’s laid-back and low maintenance for the DIYer on the go. Matte black fittings are project-ready and made from 100% authentic iron, tinted jet black for a modern look. They can be used for plumbing applications in air, natural gas, non-drinking water, oil, and steam, in addition to home decor. For outdoor projects, cleaning and sealing before use provides additional protection from the elements. Noir offers a smoother, more refined appearance than standard black iron.
