Anaco NO-HUB couplings have been produced since 1963 originally under license from the Cast Iron Soil Pipe Institute. Upon their introduction, they became the immediate alternative to the older method of joining conventional hub and spigot pipe fittings by caulking with oakum and lead and the later method of compression gaskets.
Today anaco’s coupling is providing the perfect answer for joining hubless cast iron pipe and fittings in drainage, waste and vent systems. The anaco coupling is flexible, not only enabling it to accommodate possible disparities in mating pipe but also providing a permanent seal which is superior to other, more rigid types of couplings.
