The Fernco 1051-1212 flexible pvc coupling connects asbestos cement or ductile iron pipe to cast iron or plastic pipe. Installation is as easy as sliding the coupling on and torquing the stainless steel bands down for a leak-proof connection. 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. Our couplings are built to last using 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.
