PRODUCT OVERVIEW
Protection around complex routes.
Complete the connection
Conduit and termination fittings work as a system. Match construction, size and enclosure entry rather than relying on trade size alone.
Choose the environment
Bare metal, coated metal and polymer corrugated tubing address different installation requirements. Confirm moisture, abrasion, oil and outdoor exposure.
Can this conduit carry pressurized fluid?
This range is presented for cable protection. Pressure or fluid service requires a separately qualified hose specification.
How do I request a custom specification?
Send the drawing or sample, required material, dimensions, quantity and installation conditions. We confirm the quotation, sample and applicable documentation before production.
APPLICATIONS
Where it fits
Machine wiring, control equipment, instrumentation and electrical cable protection.
SELECTION
Specify the complete product
Select trade size, clear internal diameter and minimum bend radius. Confirm material, end fittings and installation environment together. Coated and polymer corrugated constructions are also available.
