UL Listed Flexible Metal Conduit & Fittings

Kaiflex manufactures a complete range of flexible metal conduit and fittings engineered to protect electrical wiring in demanding industrial, commercial, and infrastructure environments. As a UL-listed manufacturer, we supply dry-location flexible metal conduit (UL1), liquid-tight flexible metal conduit (UL360), non-UL liquid-tight conduit, and explosion-proof flexible couplings certified to UL/IECEx/TS standards — alongside liquid-tight nonmetallic conduit (UL1660), nonmetallic corrugated tubing (UL1696), electrical nonmetallic tubing (UL1653), Chicago plenum flexible metal tubing, and cable glands.

Every flexible metal conduit series is built from galvanized steel or aluminum strip, wound to resist crushing, corrosion, and repeated flexing, making it a reliable choice for lighting circuits, machinery wiring, HVAC systems, data centers, and OA power distribution. Matching fittings — including set screw, set-in, two-screw, and 90-degree squeeze types — are manufactured to the same UL specifications, ensuring a fully compliant conduit-and-fitting system from a single source.

Whether you need standard Greenfield/reduced-wall conduit, square-lock designs for tighter bend radii, or explosion-proof solutions for hazardous locations, Kaiflex's UL flexible metal conduit product line is engineered for consistent quality and fast turnaround on OEM and bulk orders.
