These connectors are available in different sizes to suit various conduit diameters, ensuring compatibility across different setups.
2. Elbow Connectors
Elbow connectors are used when the conduit needs to change direction, typically in angles of 45°, 90°, or 180°. These fittings are ideal for navigating around corners or obstacles, allowing for smooth transitions without compromising the integrity of the conduit. They are frequently used in tight spaces or where conduits must bend to fit a specific layout.
3. End Connectors
End connectors are used to terminate the conduit at an electrical device, junction box, or panel. These fittings are designed to secure the conduit’s end and provide a reliable connection to the electrical equipment. The internal threading of the connector ensures that the conduit stays tightly fixed, preventing accidental disconnections or damage.
4. Reducer Connectors
Reducer connectors are essential when joining conduits of different sizes. These fittings provide a smooth transition between two conduit sections of varying diameters, allowing for an efficient and secure connection. They are commonly used in applications where space constraints or design requirements dictate the use of different conduit sizes.
5. Locknut Connectors
Locknut connectors are designed to secure flexible conduit fittings to an electrical box or panel. The locknut provides a firm and secure hold on the conduit, preventing any loosening or accidental disconnection. These fittings are often used in applications where the conduit needs to be firmly anchored in place for safety and reliability.
6. Waterproof and Weatherproof Fittings
In outdoor or harsh environments, waterproof and weatherproof conduit fittings are necessary to protect cables from moisture, corrosion, and extreme weather conditions. These fittings are designed with seals and gaskets to prevent the ingress of water, ensuring that the electrical system remains protected even in the most demanding conditions.
Benefits of Using Flexible Conduit Fittings
Flexible conduit fittings offer numerous advantages, making them an excellent choice for a variety of electrical installations. Some of the most significant benefits include:
