Liquid Tight Flexible Metal Conduit (UL Listed)

The liquid tight flexible metal conduit (Type LFMC) is similar in appearance to its close relative, the liquidtight flexible non-metallic conduit (LFNC). Both have a smooth grey jacket and do not leak, the LFMC type has an internal steel armour which makes it stronger and less likely to kink. Either of these raceways can be formed into gentle curves to change direction and avoid obstacles. In addition, the flexibility is very useful for terminating motors where there may be severe vibrations.

Product Description

Liquid Tight Conduit is defined as a raceway of circular cross-section having a watertight, non-metallic, sunlight resistant outer jacket over an internal flexible metal jacket with associated couplings, connectors and fittings for mounting electrical conductors. Liquid Tight Conduit is a type of conduit designed to protect electrical cables from moisture, dust, and other environmental factors. It is commonly used in both indoor and outdoor applications where exposure to harsh conditions is a concern.

Liquid tight flexible conduit is a type of electrical conduit used to protect wiring from moisture and other environmental factors. It is commonly made from a flexible material such as PVC, and is typically used in applications where a high degree of flexibility is required, such as in outdoor or underground installations.

The liquid tight nature of this type of conduit is achieved through the use of a special coating or jacketing material that is resistant to moisture and other types of liquids. This helps to ensure that the wiring remains protected even in wet or humid environments.

Liquid tight flexible conduit is often used in applications such as outdoor lighting, industrial machinery, and other situations where flexibility and protection from the elements are essential. It is also commonly used in areas where there is a risk of exposure to chemicals or other hazardous substances.

Application of Liquid Tight Flexible Metal Conduit

Purpose and Usage of Liquid Tight Conduit:

Outdoor and Industrial Environments: Liquid tight conduit is commonly employed in outdoor and industrial settings.

Protection Against Liquids: It is chosen in places like agricultural and manufacturing facilities where traditional conduit might be susceptible to damage from water or other liquids.

Underground and Underwater Installations: This type of conduit finds application in underground and underwater electrical installations.

Marine Environments: Liquid tight conduit is also utilized in marine environments, demonstrating its resistance to water-related challenges.

Electrical Circuit Protection:

Voltage Compatibility:

Liquid tight conduit is suitable for safeguarding circuits with 600 volts or lower.

UL Certification Requirement: Its use is recommended in locations where UL (Underwriters Laboratories) certification is mandated.

Diverse Applications

This includes a range of settings such as commercial buildings, industrial/power plants, shipyards, marine or boat installations, computer rooms, and similar environments.

In summary, liquid tight conduit is a versatile solution primarily chosen for its ability to protect electrical circuits in challenging environments, including those with exposure to water or liquids. It serves a diverse range of applications, meeting the requirements for both voltage compatibility and certification standards set by organizations like UL.

liquidtight flexible metal conduit (LFMC).

liquidtight flexible metal conduit allows for use in exposed or concealed locations where flexibility or protection against liquids, vapours or solids is required. It is permitted for use in designated hazardous (classified) locations and may be used for direct burial where listed and marked for this purpose.

liquidtight flexible metal conduit must not be used in areas subject to physical damage.

If liquidtight flexible metal conduit is used to minimize vibration or to provide flexibility for mobile equipment, an equipment earthing conductor must be provided. Otherwise, an internal metal sheath is sufficient.

The waterproof liquidtight flexible metal conduit is a durable alternative wiring method. Where appropriate, it contributes to an attractive appearance in commercial and industrial work, and powers pumps and fixtures in residential environments where moisture and vibration are present.
