Choose the couplings that the pros use for your next drain, waste or vent project. The Fernco 1056-442RC extra long, shielded, flexible PVC coupling quickly connects plastic (PVC, cpvc, abs, smooth wall hdpe), cast iron, copper, steel or lead pipes. Installation is as easy as sliding the coupling on and torquing the stainless-steel bands down for a leak-proof connection. Whether you're adding a new laundry sink, replacing rusted cast iron pipe, or adding a new bathroom, Fernco couplers make plumbing projects a breeze. Before you grab the primer and glue - be sure and look for the right Fernco coupling. Fernco couplings have been proudly manufactured in the USA since 1964 and are made of the highest quality elastomeric polyvinyl chloride and corrosion-resistant, rust-proof clamps. With a reputation for quality, innovation, and reliable performance, you can trust Fernco as the global leader in flexible plumbing couplings.
Unmatched quality and performance. Built to last the life of the plumbing system, Fernco couplings are made from elastomeric polyvinyl chloride for a strong, leak-proof fitting that’s resistant to chemicals and sewer gases.
No-mess installation. Fernco couplings are easy to install without the hassle of messy primers, glues and their unwanted odors.
