About Conduit

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

Thin-Wall (EMT) Conduit and Fittings

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.

Adapters for Thin-Wall (EMT) Steel Conduit

Attach conduit to a knockout in an outlet box or enclosure.

Connectors for Thin-Wall (EMT) Steel Conduit

Join pieces of conduit.

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

Attach conduit to a knockout in an outlet box or enclosure.

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

Join pieces of conduit.

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.

Medium-Wall (IMC) and Thick-Wall (Rigid) Conduit and Fittings

Connectors for Medium-Wall (IMC)
and Thick-Wall (Rigid) Steel Conduit

Join pieces of conduit.

Adapters for Medium-Wall (IMC)
and Thick-Wall (Rigid) Steel Conduit

Attach conduit to a knockout in an outlet box or enclosure.

Reducing Washers for Medium-Wall (IMC)
and Thick-Wall (Rigid) Steel Conduit

Reduce the knockout size in an outlet box or enclosure so you can attach a different size of conduit to it.

Bushings for Medium-Wall (IMC)
and Thick-Wall (Rigid) Steel Conduit

Join different sizes of conduit.

Raintight Reducing Washers for Medium-Wall
(IMC) and Thick-Wall (Rigid) Steel Conduit

Seal out moisture while reducing the knockout size in an outlet box or enclosure so you can attach a different size of conduit to it.

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.

Hazardous Location Conduit Access Ports

Also known as conduit bodies, these ports provide access to wire and cable inside thick-wall (rigid) metal conduit for pulling, splicing, and maintenance. They are also used to change the direction of a run.

Hazardous Location Conduit Bushings

Connect different sizes of conduit.

Hazardous Location Conduit Connectors

Join pieces of conduit.

Hazardous Location Conduit Adapters

Attach conduit to a knockout in an outlet box or enclosure.

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.

Adapters for Flexible Metal Conduit

Attach conduit to a knockout in an outlet box or enclosure.

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.

Fittings for Liquid-Tight Flexible Metal Conduit

These fittings seal out liquids when connecting liquid-tight flexible metal conduit to a knockout in an outlet box or enclosure.

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.

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.

Harsh Environment Liquid-Tight
Flexible Metal Conduit

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

Oil-Resistant Liquid-Tight Flexible Metal Conduit

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

Conduit Adapters

Transition between types of conduit.

Locknuts for Metal Conduit Fittings

Secure threaded metal conduit fittings to a knockout in an outlet box or enclosure.

Fittings for Continuous-Flex Liquid-Tight Plastic Conduit

Fittings for Continuous-Flex
Liquid-Tight Plastic Conduit

These fittings seal out liquid when used with continuous-flex liquid-tight plastic conduit.

Raceway

Low-Profile Raceway

Route power, data, and control cable rated up to 600 volts AC/DC.

Oil-Tight Enclosed Trough Raceway

Protect wire and cable from dust, dirt, and oil/coolant dripping—this raceway is rated NEMA 12.

Dust-Resistant Raceway

Gaskets on the covers and at connection points protect against dust as well as seeping oil and coolant.

Raceway

This raceway system is also known as wireway and wire trough.

Corrosion-Resistant Washdown Raceway

In areas exposed to washdowns, chemicals, and corrosion, install this stainless steel raceway system that has gaskets at the connection points.

Weather-Resistant Enclosed Trough Raceway

With a top that overhangs the cover, this raceway keeps out rain. It is rated NEMA 3R for protection from liquids and light splashing.

Wall-Mount Outlet Strips

Create a permanent outlet system without opening walls. These outlet strips mount to a wall with clips and hardwire to an existing electrical system.
