In essence, it’s a mechanical device designed to connect, secure, and seal flexible conduits. Flexible conduits are widely used for protecting electrical wires and cables from environmental factors, physical damage, and to facilitate easy routing.

A flexible conduit connector, as the name suggests, bridges the gap between flexible conduits, providing a junction that offers flexibility while maintaining the integrity of the conduit system. These connectors come in various designs, materials, and sizes, each catering to specific needs and requirements.

02. Types of Flexible Conduit Connectors

Flexible conduit connectors come in several types, each tailored to serve distinct purposes. Let’s explore some of the most common varieties:

1. Straight Connector: This type of connector is a simple, straight tube that connects two flexible conduits in a straight line. It’s a basic connector used when the conduit path is simple and direct.

2. 90-Degree Connector: When a conduit needs to make a sharp turn or take a right-angle bend, the 90-degree connector is employed. It ensures a smooth transition without kinking the conduit.

3. 45-Degree Connector: Similar to the 90-degree connector, the 45-degree connector allows for a gentler bend in the conduit, ideal for applications where a less severe angle is required.

4. Liquid-Tight Connector: These connectors are designed to create a seal, preventing moisture or liquid from entering the conduit. They are commonly used in outdoor or wet environments.

5. Compression Connector: Compression connectors feature a threaded design that securely fastens the conduit to the connector. They are known for their durability and resistance to vibrations.

6. NPT Connector: NPT connectors follow the National Pipe Thread standards and are widely used in conduit systems for easy installation and compatibility.

Now that we’ve covered the basics and explored the different types of flexible conduit connectors, it’s time to delve into their various applications.
