No-Hub Couplings. Engineered to connect no-hub cast iron pipe. The No-Hub Coupling has a patented shield design that provides maximum transfer of pressure from the clamps to the gasket and pipe.
Before no-hub couplings were invented, hub and spigot cast iron piping would be connected into fittings with hubs or bells by using lead, oakum, melting pots, burners, special clamps, cast iron ladles, joint runners and caulking irons.
