What types of pipe couplings are there?
Pipe couplings come in metal and plastic. Plastic pipe coupling types include ABS, CPVC, and PVC. Metal couples can be made of copper, galvanized steel, or black iron.
What size coupling do I need?
The size of coupling you need depends on your project, the pipe diameter and material your plumbing is made of. The most common diameters for water lines range from 1/2-in to 1-1/4-in. Couplings for drains are typically wider and can have a diameter up to 4 inches.
