UL 1660 Listed Liquid-Tight Flexible Nonmetallic Conduits (LFNC)

Our UL 1660 listed liquid-tight flexible nonmetallic conduits (LFNC) are made from flexible PVC and reinforced with a corrugated core, giving a fully non-metallic, corrosion-free alternative to metal conduit in wet, corrosive, or UV-exposed environments. Because there is no metal core, the conduit will not rust, and it stays flexible in outdoor installations, HVAC equipment hookups, and swimming pool or water-treatment wiring where moisture resistance is critical.

The range includes the base LFNC-B conduit (PLFNCB) and a mechanical-protection tubing variant (PLFNCB2), paired with a full family of matching fittings: straight (P50) and 90-degree elbow (P53) compression-type fittings, quick-connect straight (PP60) and 90-degree (PP63) fittings for tool-free installation, and a screw-in straight fitting (N161) for threaded enclosures.

All conduits and fittings in this series are manufactured to be sealed and liquid-tight when properly assembled, supporting compliance with NEC requirements for wet locations. As the factory, we offer OEM sizing, custom colors, and private labeling for bulk export orders.
