What is Flexible Conduit?

Flexible conduit has become a popular method of cable protection within many electrical installations. They are heavy-duty galvanized steel or plastic tubing with various threaded connections. One of the main advantages of flexible conduit is that it retains flexibility. This makes it the ideal solution for environments that require cables to be secured at specific angles, tight bends or irregular shapes.


What types of Flexible Conduits are available?

At Express Electrical our selection of flexible conduits can be split into two material types – Flexible Plastic Conduits and Flexible Metal Conduits. Both types are designed to provide the same level of protection as rigid conduits and are typically used in environments that require flexibility in installation. Each material has different advantages and disadvantages and the type that is right for you will depend on your specific application. To help you understand the features and benefits of each type, we’ve summarised some of our most popular flexible conduits below;


Flexible Plastic Conduits

Flexible plastic conduits are made from thermoplastic materials, including PE (Polyethylene) and Nylon. They are the most popular type of flexible conduit and they are frequently used to insulate and protect wires in a variety of harsh environments. One of its main advantages is that is it lightweight and easy to install. More importantly, the flexible feature of plastic conduits makes it the perfect solution for any installation that requires it to bend around unusual shapes and objects. Our new flexible plastic conduit range has been specifically designed to ensure cable protection for a wide range of applications, read below for information on some of our featured products;


  • Polypropylene Flexible Conduit - Polypropylene is a non-corrosive flexible conduit that is commonly used for cable assemblies, underfloor wiring and general cable tidying. It is very lightweight, easy-to-use and can withstand impacts and toxic materials that may pass through the cable. In comparison to other types of flexible conduit, it is one of the most economical solutions, providing a high level of protection, flexibility and usability at an affordable price. Although it does provide resistance in harsh environments, it is less durable than metal flexible conduits and may not be suitable in areas with extreme conditions that are exposed to more physical stress.

  • Nylon PA6 Flexible Conduit - Nylon PA6 Flexible Conduit is a specific type of Nylon conduit that is flame retardant, UV resistant and free of halogens. This makes this type of conduit perfect for any application that is needing less smoke and toxic gas emissions, such as train and bus installations, airports and other infrastructure projects. We stock both Lightweight and Standard nylon PA6 flexible conduits, available in a variety of different sizes. We also stock our own range of Split Nylon PA6 Conduits . The split element of these conduits make them the perfect solution to protect cables that can’t be easily threaded. The split is simply pulled apart then closed again, allowing retrofitting and maintenance to be carried out easily.

Flexible Metal Conduits

Also known as Greenfield, flexible metal conduits are made from galvanized steel tubing that is installed with threaded fittings. They are more durable that plastic conduits and can withstand harsher weather conditions. However, they are more difficult to install than other types of conduit as the material is harder to bend and cut when you compare it to plastic. It is most suitable for applications in electrical power, communication cables and wire fixtures. Below is a summary of our most popular flexible metal conduits;


  • Liquid Tight IP67 Rated Steel Flexible Conduit - This is a type of metallic conduit that has been covered with a waterproof plastic coating. It allows the conduit to keep out any moisture from the cable, ensuring safety within installation. It’s flexibility means it can be used in places that has tight bends, such as bridges, paper mills and water treatment plants. The IP67 represents one of the highest levels of protection offered by an IP rating, ensuring complete protection against any dust and protection against water and liquids up to the immersion of one meter. Therefore, this type of conduit is the ideal solution for any installations in wet conditions or any environment that is damp or humid.

  • PVC Coated Steel Flexible Conduit - PVC Coated Steel Flexible Conduit is designed to provide a high level of mechanical resistance in a highly-flexible format. The PVC coating within this conduit means that it is utilised for applications that require weather protection, such as commercial buildings and underground car parks. They are ideal for both dynamic and static applications in commercial and industrial environments. This is because the PVC jacket can stop water, oil and dirt from entering the wire, which is particularly important as steel can corrode quickly in wet conditions.

  • Bare Steel Flexible Conduit - These are great for any projects that require tight bends and edges. This type of conduit is more durable that plastic flexible conduits and can withstand harsher weather conditions. It’s ideal for applications such as underfloor wiring in public buildings such as hospitals, factories and offices.

Can I use Flexible Conduit outside?

Yes, you can! However, not every type of flexible conduit meets the regulations of electrical safety when applied outdoors and not every material is appropriate for outdoor usage. For example, flexible metal conduit, such as Bare Steel Flexible Conduit are not suitable to be used outdoors as there is a lack of water and pressure resistance.

Can I use Flexible Conduit underground?

Yes! Due to their flexibility and mechanical resistance, flexible conduits can be installed underground to protect wires against damages. However, not all types of flexible conduit is appropriate for underground applications. They can only be used underground if it fits the environment properly. More importantly, flexible conduits are only able to be used underground if they are water-tight. This means products like our Liquid Tight IP67 Rated Steel Flexible Conduit is ideal to use underground as it has protection from moisture and wet conditions.
