Is flexible conduit waterproof?

Waterproof Flexible Conduit

Flexible conduit is a vital component in electrical installations, providing protection and routing for cables. However, when it comes to wet outdoor wiring applications or areas prone to moisture, the question arises: is flexible conduit waterproof? In this post, we explore the different types of waterproof flexible conduit that Tricksall offers, exploring their features, applications, and advantages.

Introduction to Waterproof Flexible Conduit

Waterproof flexible conduit, also known as watertight flexible conduit, water-resistant flexible conduit, or waterproof flexible cable conduit, is specially designed to withstand exposure to moisture, water, and harsh environmental conditions. Unlike standard flexible conduit, which may offer some degree of protection but isn't entirely resistant to water, waterproof flexible conduit ensures reliable performance even in the most demanding settings. Within our range, we have three options for you to consider: Liquid-tight metallic IP67, Nylon polyamide IP68, and PVC spiral reinforced IP65, each with its own applications.

Applications of Waterproof Flexible Conduit

1. Outdoor Installations: Whether it's outdoor lighting, security cameras, or landscaping systems, waterproof flexible conduit is indispensable for safeguarding electrical connections against the elements. It ensures reliable performance and longevity, even in exposed outdoor settings.

Nylon PA6 Flexible Conduit, with an ingress rating of IP68, is a great choice for all external outdoor wiring systems, while our PVC spiral reinforced flexible conduit is ideal for wiring setups where wiring needs to be buried underground, particularly for garden and landscaping applications.

2. Marine Environments: In marine applications, where equipment is subjected to constant exposure to saltwater and humidity, waterproof flexible conduit provides essential protection for electrical wiring on boats, ships, docks, and marine structures.

Our Liquid-tight metallic flexible conduit and nylon PA6 conduit are very popular within the marine industry due to the protection against corrosion they offer, along with their waterproof properties.

3. Commercial & Industrial Applications: Industrial and commercial environments often present challenges such as high humidity, corrosive substances, and frequent washdowns. Waterproof flexible conduit is ideal for such settings, offering robust protection for cables in factories, warehouses, and processing plants.

You will find all three types of these flexible conduits—nylon PA6, PVC spiral reinforced, and liquid-tight metallic—in commercial and industrial applications due to the high level of protection they provide and their waterproof properties.

Advantages of Waterproof Flexible Conduit

1. Enhanced Protection: The primary advantage of waterproof flexible conduit is its ability to provide superior protection against moisture and water infiltration. Whether it's rain, snow, or humidity, this conduit effectively seals out water, safeguarding your enclosed cables from damage and ensuring uninterrupted electrical functionality.


2. Durability: Waterproof flexible conduit is engineered using high-quality materials that are resistant to corrosion and degradation caused by water exposure. This durability prolongs the lifespan of the conduit and the cables within, reducing the need for frequent replacements and maintenance.


3. Flexibility: Despite its robust construction, waterproof flexible conduit remains highly flexible, allowing for easy installation even in complex or confined spaces. Its bendability enables smooth routing of cables while maintaining the necessary level of protection against water ingress.



In conclusion, waterproof flexible conduit offers a reliable solution for protecting electrical cables in environments where moisture is a concern. Its enhanced durability, flexibility, and water-resistant properties make it a preferred choice for outdoor, marine, and industrial applications. Whether you're planning an outdoor lighting project, upgrading your marine electronics, or securing electrical wiring in an industrial facility, waterproof flexible conduit provides the peace of mind knowing that your cables are safe from water damage.
