Drain, Waste, and Vent Iron Pipe Fittings

Use these fittings in gravity-flow applications both above and below ground. They are also known as no-hub pipe fittings and soil pipe fittings. To connect, place the end of the fitting against your pipe or another fitting and connect with a low-pressure clamp-on connector (sold separately). The clamp-on connector is also known as a no-hub coupling. Fittings are for use in noncorrosive environments.
