- Application: Ideal for service panels, branch circuits, and flexible installations
Southwire Aluminum Flexible Metal Conduit, 3/4″, 25Ft
This 3/4-inch aluminum flexible metal conduit offers high-strength alloy protection for conductors and cables. Engineered to work with NEC Type FMC connectors, it provides a balance of flexibility and rigidity for routing through tight spaces and around obstacles. The alloy reduces weight compared with steel, aiding installation and handling on job sites. It cuts faster than steel and minimizes labor time without sacrificing protection.
Highlights include:
- High-strength aluminum alloy construction for mechanical protection
- Compatible with NEC Type FMC connectors
- Significantly lighter and quicker to cut than steel
- Suitable for indoor and outdoor runs where FMC is specified
OHLECTRIC Heavy Duty Aluminum Rigid Threaded Conduit Body (LB-Type)
LB-Type conduit bodies provide a robust solution for accessing interiors of rigid and IMC systems. Crafted from copper-free aluminum alloy, this unit measures 10.05 inches in length with a 2.06-inch hub length, designed for longevity in demanding environments. The threaded hubs enable secure connections to conduit runs, while the raitntight design helps protect e wiring from water intrusion when paired with gasketed covers. This product is well-suited for outdoor service entrances and wet locations requiring durable, corrosion-resistant fittings.
Key points:
- Durable aluminum alloy construction
- LB-Type with threaded connections for rigid/IMC systems
- Raintight design with gasketed cover compatibility
- Suitable for outdoor and wet environments
OHLECTRIC Heavy Duty Aluminum Rigid Threaded Conduit Body (LR-Type)
The LR-Type LR 3/4-inch conduit body provides a rugged solution for pulling and maintenance in rigid and IMC systems. Crafted from copper-free aluminum alloy, it emphasizes durability and resistance to corrosion. Its tapered hubs (NPT) enable secure, leak-resistant connections, making it reliable for long-term installations. Raintight design with gasketed covers protects the interior in outdoor settings. The compact dimensions support installations in constrained spaces while maintaining serviceability.
Highlights include:
- Copper-free aluminum alloy for corrosion resistance
- Tapered NPT hubs for versatile conduit compatibility
- Raintight with gasketed cover protection
- Suitable for outdoor and wet environments
OHLECTRIC Heavy Duty Aluminum Rigid Threaded Conduit Body (C-Type)
This C-Type conduit body is built from copper-free aluminum alloy and designed to withstand demanding environments. Its tapered NPT hubs ensure compatibility with various conduit systems and provide secure connections for pulling and splicing tasks. The raintight design with gasketed covers helps protect interior wiring from moisture in outdoor installations. This option is ideal for installations that require flexible routing with reliable access to the interior of the raceway.
Notable aspects:
- Corrosion-resistant aluminum alloy
- Tapered NPT hubs for varied conduit compatibility
- Raintight with gasketed cover protection
- Suitable for outdoor installations
Buying Guide: Red Brass and Rigid Metal Conduit Options
When selecting rigid metal conduit components, consider the environment, conduit type, and installation requirements. Key purchase considerations include:
- Material choice: Aluminum bodies are lightweight and corrosion resistant; brass and other alloys may offer different mechanical protections and thermal properties. For outdoor or wet locations, look for parts with raintight sealing and gasketed covers.
- Conduit compatibility: Verify hub sizes and threading (NPT) compatibility with rigid, IMC, and FMC systems to ensure a secure, code-compliant connection.
- Access requirements: Conduit bodies with removable covers or easy interior access reduce labor during pulling and maintenance.
- Weather resistance: For outdoor installations, raintight and gasketed designs improve longevity in rain, humidity, and temperature fluctuations.
- Ease of installation: Die-cast and lightweight aluminum options enable faster installation, especially in tight spaces.
- Code compliance: Ensure products meet local electrical codes and NEC standards for conduit fittings and access components.
In practice, combining rigid/IMC conduits with appropriately rated conduit bodies and access fittings provides a robust, maintainable electrical raceway. Compare the five highlighted options to match the specific project needs—outdoor service entrances, indoor runs, or tight spaces—while prioritizing corrosion resistance, ease of installation, and reliable access for pulls and maintenance.
