About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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.

Inline tee reducing adapters are also known as branch tees.

The 270° bend connectors are also known as P-traps.

Drain, Waste, and Vent Iron Pipe

Use this pipe in gravity-flow applications both above and below ground. It is also known as no-hub pipe and soil pipe. To connect, butt the end of a fitting up against 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. Pipe is seamless, so it has a smooth interior for unrestricted flow. It is for use in noncorrosive environments.
