About Conduit

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

Conduit and Fittings

Rigid PVC Conduit

This is also known as PVC Schedule 40 conduit.

Rigid Aluminum Conduit

This nonmagnetic aluminum conduit withstands damp and corrosive environments.

Rigid Stainless Steel Conduit

Use in food-processing and chemical plants—this is the most corrosion resistant thick-wall conduit we offer.

Thick-Wall (Rigid) Steel Conduit

This impact- and crush-resistant conduit is also known as galvanized rigid conduit (GRC).

Medium-Wall (IMC) Steel Conduit

Also known as intermediate metallic conduit (IMC), this is lighter in weight than thick-wall (rigid) steel conduit, yet it has the same strength.

Thin-Wall (EMT) Steel Conduit

Also known as electrical metallic tubing (EMT), this conduit has thin walls that easily bend with a conduit bender and can be cut with a hacksaw.

Thin-Wall (EMT) Stainless Steel Conduit

The most corrosion-resistant thin-wall conduit we offer, use this along walls and ceilings in food-processing and chemical plants.

Choose-a-Color Thin-Wall (EMT) Steel Conduit

Visually identify different runs of wire and cable along walls and ceilings with this conduit that has a painted exterior.

Liquid-Tight Flexible Conduit and Fittings

Abrasion-Resistant Liquid-Tight
Flexible Plastic Conduit

Also known as Type B, this conduit is more crush and abrasion resistant than liquid-tight flexible plastic conduit.

Liquid-Tight Flexible Plastic Conduit

The spiral design makes this conduit more flexible than abrasion-resistant liquid-tight flexible plastic conduit.

Liquid-Tight Flexible Metal Conduit

When used with liquid-tight fittings, this conduit seals out liquid. The steel core provides crush resistance, and the cover is UV light resistant.

Oil-Resistant Liquid-Tight Flexible Metal Conduit

In addition to resisting oil, this conduit resists lubricants and grease.

Food Industry Liquid-Tight Flexible Metal Conduit

Run conduit in food areas—the cover can be cleaned and sterilized without weakening or splitting. This conduit meets NSF/ANSI standard 169 for special-purpose food equipment.

Harsh Environment Liquid-Tight
Flexible Metal Conduit

The toughest liquid-tight flexible metal conduit we offer, this resists oil, chemicals, and extreme temperature fluctuations.

Extreme-Temperature Liquid-Tight
Flexible Metal Conduit

Even in temperatures as low as -50° F and as high as 220° F, this conduit stays flexible.

Flexible Conduit and Fittings

Flexible Metal Conduit

Also known as FMC, this conduit offers the crush resistance of metal combined with flexibility to handle bends in tight spaces.

Flexible Metal Conduit for Fiber Optic Cable

Protect fiber optic cable with this small-diameter conduit.

Flexible Plastic Conduit

Make tight bends in machine and equipment wiring.

Crush-Resistant Flexible Plastic Conduit

Thicker corrugations make this conduit more crush resistant than standard flexible plastic conduit.

Choose-a-Color Flexible Plastic Conduit

Visually identify different runs of wire and cable in machine and equipment wiring.

Shielded Flexible Plastic Conduit

Covered with a copper braid, this conduit protects wire and cable from electromagnetic interference (EMI) caused by motors and other equipment.

Continuous-Flex Conduit and Fittings

Continuous-Flex Liquid-Tight Plastic Conduit

Also known as Type A, this conduit meets the demands of continuous motion while sealing out liquid when used with liquid-tight fittings.

Continuous-Flex Plastic Conduit

In addition to continuous-motion applications such as robotics, this conduit is suitable for high-vibration applications.
