About Conduit

Flexible Plastic Conduit

Make tight bends in machine and equipment wiring.

Adapters for Flexible Plastic Conduit

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

Connectors for Flexible Plastic Conduit

Join pieces of conduit.

Grommets for Flexible Plastic Conduit

Preventing wear and cracks, these grommets shield the sections of your conduit that rub and bang against nearby components.

Reducers for Flexible Plastic Conduit

Connect different sizes of conduit.

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.

Adapters for Choose-a-Color
Flexible Plastic Conduit

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

Connectors for Choose-a-Color
Flexible Plastic Conduit

Join pieces of conduit.

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.

Connectors for Flexible Metal Conduit

Join pieces of conduit.

Flexible Metal Conduit for Fiber Optic Cable

Protect fiber optic cable with this small-diameter conduit.

Adapters for Flexible Metal
Conduit and Armored Cable

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

Grommets for Flexible Metal
Conduit and Armored Cable

Also known as antishort bushings, these grommets slide into the ends of conduit and armored cable to protect wire and cable from sharp edges.

Liquid-Tight Flexible Plastic Conduit

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

Adapters for Liquid-Tight Flexible Plastic Conduit

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

Connectors for Liquid-Tight Flexible Plastic Conduit

Join pieces of conduit.

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.

Fittings for Shielded Flexible Plastic Conduit

These adapters provide electromagnetic interference (EMI) protection when connecting shielded flexible plastic conduit to a knockout in an outlet box or enclosure.

Clips for Flexible Plastic Conduit

Hold flexible plastic conduit in place along walls and machines.

Continuous-Flex Plastic Conduit

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

Fittings for Continuous-Flex Plastic Conduit

One end twists into a piece of conduit for a quick connection; the other end attaches to a knockout in an outlet box or enclosure.

Conduit Reducing Adapters

Transition between conduit sizes and types.

Locknuts for Plastic Conduit Fittings
