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.

Low-Pressure Clamp-On Connectors
for Drain, Waste, and Vent

Tighten the bands on these connectors to form a strong seal on pipe or fittings.

Socket end-to-socket end connectors allow you to connect two socket-end (female) fittings without using a pipe; the connectors attach over the end of the fitting. Pipe end-to-socket end connectors connect a pipe to a socket-end (female) fitting. Pipe end-to-corrugated pipe connectors connect a rigid plastic pipe to a corrugated polyethylene pipe; a groove in the coupling matches the groove in the corrugated pipe. They are great for storm and drainage systems.

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.

Cast Iron-to-PVC Pipe Adapters
for Drain, Waste, and Vent

These adapters connect PVC waste pipe to cast iron pipe without adding bulk. Instead of securing pipes together from the outside like clamp-on couplings, these flexible adapters fit into cast iron pipe to create a tight compression seal. Adapters should fit tightly—tap with a mallet to install. Made of PVC, these fittings won't corrode when exposed to water.
