Choosing the right conduit can make all the difference to the safety, lifespan, and performance of your electrical installation. That’s where flexible conduit shines due to its strength, flexibility, and ease of us, making it perfect for everything from small domestic jobs to large commercial and industrial projects.
Unlike rigid conduit, it can bend around corners, fit into tight spaces, and handle complex layouts with ease. This flexibility saves time on site and helps protect cables from damage, ensuring a safer, cleaner, and more reliable finish. Whether you’re working indoors, outdoors, or in demanding environments, this offers versatile protection against impact, moisture, chemicals, and dust. From galvanised steel for heavy duty to PVC-coated options for added weather resistance. Also choose from multiple contractor packs that include everything you need in one pack, theres a solution for every setup.
In this guide, we’ll break down the key types of flexible conduit, highlight a few popular examples, and explore the accessories that make installation quick, secure, and compliant.
Types of Flexible Conduit
Galvanised Steel
Galvanised steel flexible conduit is designed for tough environments where wiring needs mechanical protection against crushing, impacts, or abrasion. Its steel construction ensures lasting durability and makes it ideal for industrial applications and commercial settings.
- Durable Construction: Strong galvanised steel provides excellent resistance to wear.
- Increased Safety: Protects cables against accidental damage.
- Versatile Applications: Suitable for commercial and industrial projects.
A great example of this that we offer is the Termtech PREM20GALV-50M | Flexible Conduit Galvanised Steel 20mmx50m.
Galvanised PVC-Coated
For projects exposed to moisture, chemicals, or outdoor conditions, galvanised conduit with a PVC coating is the go-to choice. The steel provides core strength, while the PVC coating adds an extra layer of weather resistance and corrosion protection.
- Weather Protection – PVC coating shields against rain and environmental elements.
- Long Lifespan – Combines the toughness of steel with the resilience of PVC.
- Cost-Effective – Reduces the need for frequent replacements.
An example of what we can offer is the Termtech PREM25GALVPVC-10 | Flexible Conduit Galvanised Steel PVC Coated 25mmx10m.
Contractor Packs
For electricians and contractors looking for a quick and convenient solution, contractor packs offer everything you need in one box. These packs typically include a length of flexible conduit and a set of compatible glands, simplifying procurement and installation.
- All-in-one Kit – Conduit and glands included.
- Time Efficient – Perfect for fast, tidy installations.
- Easy Installation – Split glands make retrofitting cables simple.
We would recommend the Termtech M25CONN-PK | Black Conduit 10m & 10 Split Glands M25.
Essential Accessories for Flexible Conduit
To get the most from your flexible conduit installations, using the right accessories is key. We stock a range of high-quality glands that ensure secure, reliable, and compliant connections.
Glands
We have already mentioned glands in terms of the contractor packs but for galvanised/PVC-galvanised you will need different glands. We offer a mixture of fixed and swival glands in various sizes (M20/25/32) to provide robust protection for your job.
The difference between the two glands is in their name so you can decide which one you need whether you want a fixed straight line connection or to connect on a bend. Both of these glands are IP54 rated when fitted with the conduit, just remember to tightly secure them to ensure this.
They are suitable for industrial and commercial projects, also if you want added cable protection for outdoor projects. The flexibility allows you to route the cable to your needs.
Choosing the Right Flexible Conduit
When selecting a flexible conduit, consider the following:
- Environment – Is it indoors, outdoors, or in a corrosive area?
- Levels of Protection – Does it need to resist mechanical impact, water, or chemicals?
- Ease of Use – Would a contractor pack save you time and effort?
By matching the conduit type to your projects specific needs, you’ll ensure increased safety, lasting durability, and efficient installation.
Final Thoughts
Flexible conduit provides a reliable solution for protecting wiring across a wide range of applications. From heavy-duty galvanised steel to PVC-coated options for harsh environments, and contractor packs for quick jobs, there’s a solution for every project. Combined with swivel and fixed glands, these accessories complete the system, ensuring professional, compliant installations every time.
