Electriduct 1/4 Inch PVC Coated FMC
Size and construction: Inside diameter 0.23″, outside diameter 0.35″, 10 feet long. The conduit uses a galvanized steel core with a single-buckle structure that enhances tensile strength and is liquid PVC coated. This combination provides durability, flexibility, and a smooth inner surface to ease cable passage. Key specs include waterproofing, corrosion resistance, flame retardancy, UV resistance, UL94-V2 rating, and an operating temperature range from 14°F to 176°F (-10°C to 80°C). RoHS compliant for safer materials handling.
Electriduct 1 Inch PVC Coated FMC
Size and construction: Inside diameter 0.98″, outside diameter 1.16″, 10 feet long. Features a galvanized steel conduit core with a single-buckle structure for added tensile strength and a liquid PVC coating to improve durability and leak-proof performance. The inner bore remains smooth for easy wire routing. Specifications mirror the 1/4″ model: waterproof, corrosion resistant, flame retardant, UV resistant, UL94-V2, 14°F to 176°F (-10°C to 80°C) operating range, RoHS compliant.
Electriduct 1/2 Inch PVC Coated FMC
Size and construction: Inside diameter 0.47″, outside diameter 0.61″, 10 feet long. It uses a galvanized steel conduit core with a single-buckle structure to boost tensile strength, coated in liquid PVC for enhanced durability, flexibility, and leak resistance. Inner bore remains smooth for easy cabling. Specs align with waterproof, corrosion resistant, flame retardant, UV resistant, UL94-V2, operating range 14°F to 176°F, RoHS compliant.
NIDAYE 1/2 Inch PVC Coated FMC
Size and construction: Inside diameter not specified; 50 feet length. The conduit uses a galvanized steel core with a single-buckle structure for tensile strength, coated in liquid PVC to provide durability and leak-proof performance with a smooth inner bore for ease of wire passage. It is water-proof, corrosion resistant, flame retardant, UV resistant, with operation temperature from 14°F to 176°F. Intended for low voltage applications and flexible, high-mechanical-protection needs in static and dynamic scenarios.
Qlvily 3/4 Inch PVC Coated FMC
Size and construction: 3/4″ nominal size, 25 feet length. Built with a high-strength galvanized steel core and a single-buckle design to improve tensile strength. The exterior is coated with liquid PVC to increase durability and flexibility while maintaining a smooth inner surface for easy cable routing. The product is RoHS compliant, suitable for low- to medium-voltage applications, and designed to protect wires from physical damage and environmental exposure.
Buying Guide
Key considerations when choosing PVC coated FMC include size compatibility, voltage rating, and environmental exposure. For residential electrical runs, smaller diameters like 1/4″ and 1/2″ offer tight bends and flexible routing, while 3/4″ and 1″ options serve higher cable counts or larger conductors. Look for the following:
- Conduit core: Galvanized steel cores with a single-buckle design provide tensile strength and fatigue resistance for dynamic or long runs.
- PVC coating integrity: A liquid PVC outer wrap adds water resistance, chemical resistance, and leak-proof performance, while preserving a smooth inner bore for easier installation.
- Environmental tolerance: Check temperature range and UV exposure ratings to ensure the conduit handles outdoor or garage environments without cracking or degradation.
- Waterproof and flame resistance: UL94-V2 rating and moisture resistance are important for damp spaces and outdoor installations.
- Voltage suitability: Most FMCs in this category are intended for low-voltage or general-purpose wiring; verify compatibility with your circuit specifications before use.
- RoHS compliance: Ensures the product avoids certain hazardous substances, supporting safer handling and disposal.
- Length and flexibility: Longer runs reduce the need for fittings but require careful routing. Shorter lengths can simplify installations in tight spaces.
- Compatibility with fittings: Confirm compatible connectors, clamps, and boxes that match the conduit size.
In choosing between brands, consider long-term durability, availability of replacement parts, and the suitability of coatings for your environment. For low-voltage applications or flexible, damaged-prone areas, a well-coated FMC offers significant protection against moisture and oils. Always follow local electrical codes and manufacturer guidelines when planning wiring projects.
