The dimensional flexibility of Fernco couplings ensures leak-proof pipe seals on virtually any pipe material: plastic, cast iron, asbestos cement, clay, concrete, steel, copper and ductile iron. All flexible couplings are clearly marked with part number, size, and pipe material that the coupling will connect to.
Intended for use with DWV systems, no-hub couplings are used to join cast iron soil pipe that does not have the traditional Hub and Spigot. No-Hub couplings have an inner gasket made of a synthetic rubber compound most often neoprene. The inner gasket is surrounded by an outer stainless steel shield or band that are normally installed using a torque wrench. Medium and heavy-duty couplings generally, they have more clamps and provide a greater band load than standard no-hub couplings.
VMS stocks Fernco connectors, caps and no-hub couplings for a wide variety of pipe materials and diameters.
