PVC Non-metallic Mechanical Protection Tubing (NMPT)
The PLFNCB2 series is a high-performance PVC Flexible Corrugated Tubing designed for superior Mechanical Protection (NMPT) in demanding environments. Engineered from premium thermoplastic polyvinyl chloride (PVC), this tubing features a smooth inner surface for easy wire pulling and a corrugated exterior for maximum structural integrity.
What sets the PLFNCB2 series apart is its integrated reinforcement member, which enables extraordinarily high flexibility while maintaining exceptional self-support and crush resistance. Its lightweight construction and "easy-to-cut" nature make it the ideal choice for quick on-site assembly, significantly reducing labor time and costs.
Technical Excellence & System Compatibility:
1. Rugged Durability: Fully RoHS compliant, with specialized additives to resist UV radiation, aging, and industrial oils.
2. Optimized Protection: The reinforced design ensures long-term protection against mechanical stress without compromising bend radius.
3. Watertight System Integration: To achieve maximum waterproof efficiency, the PLFNCB2 series is designed to work seamlessly with our Liquid Tight Fitting series (P50, P51, P52, P53, PP60, PP63, and N161).
Core Applications:
Highly recommended for electrical protection in Machine Tools, Renewable Energy (Solar/Wind), Telecommunications infrastructure, and complex industrial automation systems.

Frequently Asked Questions (FAQ) - UL 1660 Non-metallic Conduit
Q1: What does "LFNC-B" stand for in UL 1660 standards?
A: LFNC-B stands for Liquid-tight Flexible Non-metallic Conduit (Type B). It features a smooth inner surface with integrated reinforcement within the conduit wall, providing excellent watertight and airtight performance for electrical wiring.
Q2: Is this PVC tubing suitable for outdoor HVAC installations?
A: Yes, absolutely. Our UL 1660 conduit is sunlight resistant and UV-stabilized, making it the industry standard for outdoor HVAC units (A/C whips), heat pumps, and refrigeration systems.
Q3: Can I use this conduit in corrosive or wet environments?
A: Yes. Being non-metallic, it is inherently corrosion-resistant and will not rust. It is perfect for wet locations, chemical plants, and marine applications where metal conduits might fail.
Q4: What temperature range can the UL 1660 conduit withstand?
A: This series is designed to handle standard industrial and outdoor temperatures. It remains flexible in cold weather and maintains its structural integrity in high-heat environments typically found in rooftop electrical runs.
Q5: Do I need special tools to cut and install this tubing?
A: No special tools are required. It can be easily cut with a standard PVC cutter. For a 100% liquid-tight seal, we recommend using Kaiflex UL-listed non-metallic fittings (straight or 90-degree connectors).
