Quick-Connect Corrugated Conduit Fittings

Fast Snap-In Connection. Secure Conduit Retention. Reliable Cable Protection.

Quick-connect corrugated conduit fittings are designed to connect flexible corrugated tubing to electrical enclosures, machinery and equipment housings. The snap-in connection allows the conduit to be installed quickly, while the threaded end provides a mounting interface for equipment cable entries.

Quick Snap-In Design

The integrated retaining mechanism engages with a compatible corrugated conduit profile, providing a secure connection without separate conduit-side fastening accessories.

Key benefits include:

Fast Installation: Push-in connection simplifies conduit assembly.
Secure Retention: Internal locking features help prevent accidental conduit pull-out.
Cable Protection: Creates a protected transition from flexible conduit to equipment entry.
Easy Integration: Threaded mounting options for different equipment interfaces.

Designed for Corrugated Conduit Systems

Available for corrugated conduit sizes from AD10.0 to AD54.5, with multiple mounting thread options. Compatible conduit dimensions and corrugation profiles should be confirmed before installation to ensure proper locking engagement.

Typical Applications

Industrial Machinery: Connecting protective conduits to motors, equipment housings and machine control systems.
Electrical Cabinets: Organized entry of conduit-protected wiring into control panels and junction boxes.
Automation Equipment: Protecting sensor, signal and power cables routed through flexible conduits.
Vehicle Wiring: Conduit connections for protected electrical harnesses in suitable vehicle equipment.
Equipment Maintenance: Replacement and installation of conduit fittings on existing machinery.

Find the Right Conduit Connector

Select according to the corrugated conduit outside diameter and profile, equipment thread size, mounting clearance and required environmental protection.

Different conduit sizes, thread configurations and packaging options are available according to product specifications.

Frequently Asked Questions

1. What is a corrugated conduit connector used for?

It connects flexible corrugated cable protection tubing to electrical enclosures, machinery and equipment housings.

2. How does the quick-connect mechanism work?

The conduit is inserted into the fitting, where internal retaining features engage with a compatible corrugated profile to secure the connection.

3. How do I choose the correct connector size?

Check the conduit AD size, actual outside diameter, corrugation profile and equipment mounting thread.

4. Can this connector join two corrugated conduits?

This threaded fitting is primarily designed for conduit-to-equipment connections. A dedicated conduit-to-conduit coupler is required to join two conduit sections.

5. Is the connector waterproof?

The product page specifies IP68. Actual ingress protection must be verified for the complete conduit-and-fitting assembly, including any required seals and installation conditions.
