Smooth-jacket conduit cutaway
Section through a smooth outer jacket and interlocked metal core. Packing and jacket construction are specified separately.
UNDERSTAND THE RANGE
Selecting flexible metal conduit
Helically formed metal conduit provides a flexible route around electrical cables. Select the construction together with bore, bend radius and compatible termination fittings.
Construction
Compare uncoated and coated designs against the installation environment.
Cable route
Confirm the complete cable bundle, connector clearance and minimum permitted bend radius.
Connections
Match the conduit construction and outside diameter to the fitting, then check the enclosure thread.
Environment
Identify abrasion, moisture, oils, temperature and whether the route moves during operation.
Typical application context
Cabinet-to-machine connections, equipment wiring and protected cable routes around machinery.
Is trade size the same as internal diameter?
Not necessarily. Use the model drawing for the actual bore and outside diameter; check fitting compatibility separately.
Does a metal conduit automatically provide a liquid-tight assembly?
No. Sealing depends on the conduit construction, fittings and installation. Request the performance documentation for the proposed assembly.

BUYER GUIDE
How to Select Flexible Metal Conduit for Industrial Cable Protection
Select flexible metal conduit by cable bundle size, movement, mechanical exposure, environment, and the required fitting system. Confirm actual internal diameter, bend radius, material, jacket, and connection details. Treat ingress protection and electrical continuity as properties requiring documented system verification.

BUYER GUIDE
Coated vs Uncoated Flexible Metal Conduit: What Changes?
Choose coated metal conduit when the specified jacket and matching fittings address the installation's liquid or surface exposure. Consider uncoated conduit when its documented mechanical, temperature, and environmental properties fit the job. A coating alone does not establish liquidtight performance.

BUYER GUIDE
Cable Gland Diameter and IP Ratings: Selecting the Complete Seal
Choose a cable gland whose declared clamping range includes the cable's actual outside diameter, then verify enclosure mounting and installation conditions. An IP marking describes tested ingress protection; it does not compensate for an incorrect cable fit or incomplete assembly.

Behind the conduit construction.
See forming and processing views, then discuss the finished bore, core construction, coating and fittings for your cable route.
Metal conduit forming
Formed metal conduit provides a flexible routing structure. Profile, strip material and finished bore need to match the approved product construction.
Conduit processing
Conduit dimensions and jacket construction are defined for the intended cable route. Confirm the core, outside diameter, coating and matching fittings when ordering.
