About Conduit

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

Conduit Type

EMT

The most common choice for indoor walls and ceilings

9 products

IMC

Thinner walls than RMC for less weight and more room for wiring

Conduit Type

RMC

The choice for maximum impact and crush resistance

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 Grommets

Threaded

Connection

Protect wire from sharp edges as you pull it through by adding these grommets to the ends of conduit.

Polypropylene—Lightweight and chemical resistant, these fittings won't corrode.

Thin-Wall (EMT) Metal Conduit and Fittings

With a thinner wall, this conduit is a lighter alternative to IMC and RMC. The most common choice for indoor walls and ceilings, it shields wiring from scrapes and bumps. EMT can dent or crush from impact, however, so it should be routed away from high‑traffic areas where carts and vehicles pass through.

Conduit Grommets

Push-In

Connection

Protect wire from sharp edges as you pull it through by adding these grommets to the ends of conduit.

Flexible Metal (FMC) Conduit and Fittings

Make tight bends and protect wiring from being crushed. This corrugated conduit snakes around corners where rigid metal conduit won’t fit. For use indoors, it’s ideal for short connections or runs through walls in spaces that require both flexibility and durability.

Conduit Grommets

Push-In

Connection

Protect wire from sharp edges as you pull it through by adding these grommets to the ends of conduit.
