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 Bushings

Threaded

Connection

Threaded internally and externally to connect two different-sized pieces of conduit.

Aluminum—One-third the weight of steel that's the same size. Aluminum is also nonmagnetic to prevent electrical interference in nearby equipment.

Low-Pressure Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications. To prevent cracking, do not tighten more than a _1/4-turn past hand tight.
