Flexible Metal Conduit & Fitting (UL1)

Kaiflex's UL1 Series covers UL 1 Listed flexible metal conduit (FMC) and matching fittings engineered for dry-location electrical wiring in the United States and Canada. Manufactured from helically wound galvanized steel or aluminum strip, this series is recognized under UL File Number E238089, giving specifiers and importers a verifiable safety record for use in commercial, industrial, and residential raceway systems.

The range includes the PRWG Series (galvanized steel, reduced-wall/Greenfield construction) for general-purpose branch circuit wiring, the XP3 Series square-lock steel conduit for higher crush resistance, the PRWA Series aluminum conduit for lightweight, corrosion-resistant applications, and the XPO Series flexible oval steel conduit designed for office furniture and partition wiring. Each conduit type is paired with a full line of Bx-Flex fittings — set screw, set-in, two-screw, 90-degree squeeze, straight squeeze, and screw-in coupling types — covering trade sizes from 3/8" to 4" for compatible connection to steel and non-metallic boxes.

All products in this series are produced at Kaiflex's own certified factory in Guangde City, Anhui Province, China, with full traceability and consistent quality control for OEM and bulk export orders.
