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.

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

Connector (Shown with Clamp)

For Use With: Water
Temperature Range: -10° to 140° F
For Pipe Material: Steel, PVC Plastic

Connect two pipes that are up to 100 feet apart—cut the connector to the length you need and attach a clamp (sold separately) to each end. Connectors fit standard-wall (Schedule 40) and thick-wall (Schedule 80) pipe. They are made of flexible PVC, which is weatherproof and ozone resistant.

Clamps are corrosion-resistant galvanized steel. You'll need one clamp for each connecting point.

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.
