Since 1963, Anaco has been the leader in no-hub coupling technology. From our complete line of Standard No-Hub couplings, to Husky 4000 and 2000 series, to both shielded and unshielded transition couplings, Anaco produces the broadest line of couplings for connecting cast iron in DWV systems, as well as connecting cast iron to virtually all types of DWV pipe and fittings.
