How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

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.

Low-Pressure Clamp-On Connectors for Drain, Waste, and Vent
To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.
Saddle-tap adapters allow you to tap into an existing pipeline. They have wraparound clamps that provide nearly 360° contact with pipe; as the clamps are tightened, pressure is uniformly distributed around the pipe for maximum support. To install, shut down your line and drill a hole in the pipe where you want to create a connection. Position the saddle over the hole and tighten the clamps.

Vacuum Fittings for Steel Tubing
- For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
- Temperature Range: -10° to 180° F
- Tubing: Galvanized Steel: Use with steel, galvanized steel
Steel: Use with steel
Use these fittings to create an air vacuum system without the hassle of brazing and welding. Insert two fittings into a clamp (sold separately) and tighten to form a secure seal.
Galvanized steel fittings have fair corrosion resistance. Fittings without a finish should only be used in noncorrosive environments.
