About Conduit

Compare rigid and flexible conduit materials and identify the trade size for compatible fittings.

Medium-Wall (IMC) and Thick-Wall (RMC) Metal Conduit and Fittings

The industry standards, IMC and RMC conduit systems offer the most durable protection indoors, outdoors, and underground. Both types have the same outside diameter, so they use many of the same fittings. This interchangeability makes retrofits easier and reduces the parts you need to keep on hand.

Conduit Unions

Threaded Connection

When working in tight spaces, use unions to connect conduit so you only have to twist the fittings, not the conduit itself.

Zinc-Plated Iron—Resist occasional exposure to moisture but not as strong as zinc‑plated steel.
