What Type of Flexible Metallic Conduit is the Best Choice for Use in Wet Areas?

Sep. 14, 2023

When it comes to electrical installations in wet areas, choosing the right conduit is of paramount importance. The conduit you select not only ensures the safety of your electrical system but also determines its longevity and performance. In this comprehensive guide, we will explore the various options available for flexible metallic conduit in wet areas and help you make an informed decision.


 Understanding the Importance of Flexible Metallic Conduit


Flexible metallic conduit, often abbreviated as FMC, is a critical component in electrical installations. Its primary purpose is to protect electrical wires and cables from environmental factors, physical damage, and moisture. In wet areas, such as outdoor spaces, bathrooms, and kitchens, the choice of conduit becomes even more crucial due to the increased risk of exposure to water.

 Types of Flexible Metallic Conduit


There are several types of flexible metallic conduit available in the market, each with its unique characteristics. To determine the best choice for wet areas, it's essential to familiarize yourself with these options:


1. Flexible Metal Conduit (FMC): This conduit is constructed from a helical wound strip of steel. It is highly durable and resistant to corrosion, making it suitable for wet areas where moisture exposure is a concern. FMC is also known for its flexibility, allowing it to navigate tight corners and bends easily.


2. Liquidtight Flexible Metal Conduit (LFMC): LFMC is similar to FMC but comes with an additional PVC coating that provides extra protection against moisture and liquids. This type of conduit is ideal for areas where there is a high probability of water exposure.


3. Flexible Metallic Tubing (FMT): FMT is a lightweight conduit option made of aluminum or steel. While it is less resistant to moisture compared to FMC and LFMC, it can still be used in damp locations if adequately sealed and protected.

 Factors to Consider for Wet Areas


When deciding which type of flexible metallic conduit is the best choice for wet areas, consider the following factors:


 1. Moisture Levels: Assess the specific moisture levels in the area where the conduit will be installed. High humidity and frequent exposure to water require a more robust solution like LFMC.


 2. Environmental Conditions: Consider the overall environment, including temperature fluctuations and the presence of corrosive substances. FMC and LFMC are more suitable for harsh conditions.


 3. Flexibility Requirements: Determine how much flexibility the conduit needs to navigate complex routes. FMC's flexibility makes it a top choice for installations with tight corners and bends.


 4. Local Regulations: Always adhere to local electrical codes and regulations when selecting conduit. Compliance ensures safety and avoids potential legal issues down the road.


 The Best Choice for Wet Areas


After careful consideration of the various factors, it becomes evident that Liquidtight Flexible Metal Conduit (LFMC) is the best choice for wet areas. Its combination of steel strength and PVC moisture protection makes it an ideal candidate for environments where water exposure is a concern. LFMC's flexibility also ensures that it can be easily routed through challenging spaces, maintaining the integrity of your electrical system.


Furthermore, LFMC offers a high level of corrosion resistance, making it suitable for outdoor installations where it may be exposed to the elements. Its durability ensures that your electrical system remains safe and operational for years to come, even in challenging conditions.



The choice of flexible metallic conduit in wet areas should not be taken lightly. To ensure the safety and longevity of your electrical system, opt for Liquidtight Flexible Metal Conduit (LFMC). Its superior moisture protection, flexibility, and durability make it the best choice for environments where exposure to water is a concern.
