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

12 products

IMC

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

24 products

Conduit Type

RMC

The choice for maximum impact and crush resistance

33 products

PVC Schedule 40

Lighter than Schedule 80 but may dent or crush from heavy impact

12 products

Conduit Bodies

Installed between runs of conduit, bodies have a removable cover for access inside the system. This makes it possible to pull, splice, and change the direction of wire without dismantling the run.

90° Elbow (LB)

Change the direction of your run.

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

316 Stainless Steel—Our most corrosion-resistant fittings won't degrade when exposed to salt water and harsh chemicals.

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

PVC—Lightweight and chemical resistant, these fittings won't corrode. PVC cement (not included) is required when joining conduit to fittings with push-in connections.
