Types of Flexible Conduit Pipes

  • Flexible Metal Conduit (FMC)

Flexible metal conduit (FMC, commonly called greenfield or flex) is produced by helically coiling a self-interlocked ribbed strip of aluminum or steel, creating a hollow tube through which electrical wires can be routed. FMC is mainly used in dry locations where installing EMT or other rigid conduit would be impractical, yet metallic strength is still needed to protect conductors. The flexible tubing does not retain a permanent bend and can move freely.

Flexible metal conduit (FMC) features a spiral construction that allows it to navigate through walls and other structures. FMC safeguards electrical wiring in both commercial and industrial buildings.

FMC can serve as an equipment grounding conductor if certain requirements are met regarding the trade size and length of FMC used, depending on the amperage of the circuits inside the conduit. Generally, an equipment grounding conductor must be installed through the FMC with sufficient ampacity to carry the fault current potentially imposed by the largest circuit contained within the conduit.

Key Points to take away

  • Spiral metal construction
  • Suitable for dry indoor locations
  • Ideal for short runs and tight bends
  • Liquid-tight Flexible Metal Conduit (LFMC)

As the name suggests, this is a type of flexible electrical conduit that performs exceptionally well in wet environments. It consists of a metal core with an extruded thermoplastic jacket, forming a liquid-tight conduit. Galvanized steel is commonly used for the stripwound core, which includes an integral bonding wire. However, in 2023, NEC approved stainless steel stripwound cores when installed with a separate grounding conductor or bonding jumper.

Various thermoplastic materials are UL-approved for conduit jackets. These jackets provide resistance to heat, cold, corrosion, prolonged UV exposure, and static electricity.

Some typical applications for LFMC conduit include:

  • Outdoor and underground installations: Liquid-tight conduit is ideal for locations exposed to moisture or water, such as irrigation systems, air conditioners, or outdoor lighting. UL-listed conduit suitable for burial in the ground or in concrete is marked with DIR BURIAL or DIRECT BURIAL. (For more details, see What is Direct Burial?)
  • Hazardous locations: UL-listed liquid-tight conduit offers protection against moisture and corrosion, making it approved for use in Class I Div. 2 Hazardous Locations where exposed wiring may pose a risk.

Key Points to take away

  • Plastic-coated metal for watertight protection
  • Used outdoors or in wet environments
  • Compatible with air conditioners, pumps, and outdoor equipment

Flexible Non-Metallic Conduit (FNC / ENT)

Non-metallic conduits are typically manufactured from PVC (polyvinyl chloride), one of the most widely used synthetic plastic polymers worldwide.

For installations located above ground, these conduits must exhibit properties such as flame resistance, strength, and protection against environmental conditions including heat, sunlight, and low temperatures.

In contrast to metallic conduits, which are often applied to protect sensitive circuits, non-metallic conduits are valued for their versatility, as they can be installed both above and below ground, supporting multiple or parallel run arrangements.

Key Points to take away

  • Made of corrugated plastic
  • Lightweight and easy to handle
  • Used for indoor wiring and metal/wooden structures

Applications of Flexible Conduit Pipes

  • Indoor electrical wiring for residential and commercial buildings
  • Connecting equipment that may require movement or adjustment
  • Outdoor electrical installations requiring watertight protection
  • Industrial machinery and robotics wiring
  • Temporary setups and renovations where rigid conduit is impractical

Advantages of Flexible Conduits

  • Easy to install in tight or curved spaces
  • Reduces need for precise measurements and bends
  • Can absorb vibrations and minor movements
  • Available in different materials for specific environmental requirements
  • Provides protection to electrical wires from mechanical stress
