Flexible Conduit Accessories
The Flex‑It Range of Flexible Conduit Accessories
The Flex‑It range of flexible conduit accessories continues to grow, now including specialist R-Series plastic conduit clips designed specifically for our two most popular sizes of polypropylene corrugated conduit, 20 mm and 25 mm. These clips are part of our wider cable accessories selection and offer a simple, cost-effective solution for securing conduit to fixed surfaces. Each clip can be easily installed with a standard screw, not included.
Our selection of metal locknuts has also been expanded, with options in both galvanised steel and nickel-plated brass, allowing you to choose the right finish for your application or environment.
In addition, our metal conduit couplers are now available in nickel-plated brass in sizes from 16 mm to 50 mm, providing durable and reliable connections for your conduit runs.

FAQ's
At Flex‑It, we offer a wide range of flexible conduit accessories, including couplers, clips, lock nuts and split cable insert tools, all designed to complement our full range of metal and plastic conduits.
Different types of conduits require specific fittings, so it’s important to choose accessories that match your conduit type.
For instance, if you need to join separate metallic or plastic conduit segments in the same circuit, a conduit coupler is essential. We stock metallic threaded couplers in galvanised steel or nickel-plated brass, as well as plastic couplers suitable for our R-series polypropylene corrugated conduits.
If your goal is to secure conduits to panels without extra fasteners, our selection of metallic and plastic conduit clips is ideal. These accessories are perfect for both commercial and domestic wire management projects.
For guidance on which flexible conduit accessories are right for your installation, or for expert advice, the Flex‑It team is always happy to help.
Not all flexible conduit accessories are necessary, and the majority of fittings are simply to make trickier installations a bit easier.
However, you will need to purchase a compatible coupler to go along with your flexible conduits and ensure a seamless circuit.
Our metallic and plastic conduit couplers are available in a variety of lengths – from 16mm to 50mm – so you’re bound to find something that meets your project requirements.
