Electrical conduit is the tubing that houses and protects your electrical wiring from damage, moisture, and interference. Using the right conduit not only keeps wires safe—it also helps you meet local building and electrical codes. From residential wiring to commercial installations, conduit keeps your system organized and secure.

Whether you’re a professional contractor or a DIY enthusiast, we make it easy to find and choose the right conduit for your situation.

• Rigid Metal Conduit (RMC) offers the highest level of physical protection for wiring. Made from heavy-duty galvanized steel, it is commonly used in industrial settings, exposed locations, and outdoor installations where strength and durability are critical.
• Intermediate Metal Conduit (IMC) provides similar protection to RMC but with a lighter weight. It is easier to install while still offering excellent resistance to impact and corrosion. This makes IMC a popular choice for commercial and professional electrical projects.
• Electrical Metallic Tubing (EMT), often called “thin-wall” conduit, is lightweight and easy to bend and cut. It is widely used for indoor wiring in residential and commercial buildings. EMT is ideal for projects that require flexibility, speed, and clean installation.
• Rigid PVC Conduit - Rigid PVC conduit is non-metallic, corrosion-resistant, and well-suited for underground, outdoor, and wet environments. It is commonly used for landscape lighting, buried wiring, and applications where moisture protection is essential.
• Flexible Metal Conduit (FMC) allows wiring to bend around obstacles and tight spaces. It is often used for short runs, equipment connections, and areas where rigid conduit is impractical. FMC provides durability with added flexibility.
• Liquid-Tight Flexible Conduit (LFMC/LFNC) is designed for locations exposed to water, oils, or chemicals. It features a protective coating that seals out moisture, making it ideal for outdoor equipment, HVAC systems, and industrial machinery.
• Electrical Nonmetallic Tubing (ENT), sometimes called “smurf tube,” is a flexible plastic conduit commonly used in residential construction. It is lightweight, easy to install, and well-suited for running wires through walls, ceilings, and framing in new builds.
