Product details

The no-hub coupling has a patented shield design that provides maximum transfer of pressure from the clamps to the gasket and pipe. Engineered to connect no-hub cast iron pipe in applications, replacing the less-efficient hub and spigot.
No-hub couplings come in handy when your pipes are in hard-to-reach places, cannot be moved for repairs or when replacing just a section of piping when hubs are not available. 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 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.
