Conduit Collars, Ferrules and Sealing Components for Industrial Cable Protection Systems
Collars, ferrules, seals, and sleeves are important components used to secure, seal, and adapt flexible conduit systems in industrial cable protection installations.
These accessories support conduit-to-fitting connections, sealing interfaces, and mechanical transitions between conduits, cables, and fittings. Collars and ferrules are designed to ensure reliable connections while maintaining cable protection and system integrity in demanding industrial environments.
Different collar and ferrule types are used depending on the conduit system, fitting type, and installation requirements.
FLEXAquick® quick-connect fittings and ROHRflex® flexible corrugated conduits are flagship product lines from IBIS Electro-Products Corp., specializing in high-performance electrical conduit systems for industrial automation, AI infrastructure, wind nacelle wiring, and public transit vehicle applications.

How Conduit Ferrules and Collars Work
Ferrules and collars reinforce the connection between flexible conduits and conduit fittings.
Ferrules are installed over the end of the conduit before the fitting is assembled. They strengthen the conduit wall and help ensure a secure mechanical connection between the conduit and the fitting body.
Thrust collars are used with specific conduit fittings to provide proper compression and support during installation, ensuring reliable conduit retention and sealing performance.
Typical Applications
• Industrial automation systems
• Machine wiring and equipment installations
• Robot and cobot wiring systems
• Electrical control panels
• Data infrastructure cable routing
• Wind turbine nacelle wiring systems
Frequently Asked Questions About Conduit Ferrules and Collars
When should a conduit ferrule be used?
Ferrules are used when the conduit end must be reinforced to ensure a secure connection between the conduit and the fitting.
What is the purpose of a thrust collar?
Thrust collars help maintain proper compression during installation and provide additional mechanical support for conduit fittings.
Are ferrules required for all conduit fittings?
Not all conduit fittings require ferrules. Their use depends on the conduit system and fitting design.
Do ferrules improve conduit retention in fittings?
Yes. Ferrules help improve conduit retention by reinforcing the end of the flexible conduit where it enters the fitting.
Flexible conduits can compress or deform when a fitting is tightened. Installing a ferrule over the conduit end strengthens the conduit wall, helping maintain its shape and allowing the fitting to grip the conduit more securely.
This reinforcement helps ensure a reliable mechanical connection between the conduit and the fitting while also reducing the risk of conduit damage during installation.
