Electriduct 1/2″ PVC Coated Liquid-Tight Conduit – 10 Feet
The Electriduct 1/2″ PVC-coated liquid-tight galvanized steel flexible conduit combines a galvanized steel core with a durable liquid PVC coating. The interior is smooth to ease wire pulling, while the coating adds durability and leak resistance. Its outside diameter and inner dimensions are designed to balance rigidity and flexibility for routing through confined spaces. Specifications include waterproofing, corrosion resistance, flame retardancy, UV resistance, and RoHS compliance, with an operating range from 14°F to 176°F (-10°C to 80°C). This option is suitable for outdoor or indoor use where moisture exposure is a concern.
Electriduct 1/4″ PVC Coated Liquid-Tight Conduit – 10 Feet
This 1/4″ PVC-coated version mirrors the 1/2″ model, offering a smaller footprint for tight spaces. Its galvanized steel core retains strength, while the PVC coating supplies additional protection against water ingress and abrasion. The conduit remains flexible enough for routing in complex installations and maintains a smooth inner surface to support wire pulling. With waterproof, corrosion-resistant, flame-retardant properties, and RoHS compliance, it performs reliably in varied environments, from garages to outdoor conduits.
Southwire Alflex Aluminum RWA Metal Conduit
Southwire’s Alflex Aluminum RWA metal conduit is crafted from a lightweight aluminum alloy, with a helically formed metal strip that provides continuous interlocking flexibility. This conduit is UL-listed for various installation scenarios—concealed or exposed—and designed to withstand impact and crushing while remaining corrosion-resistant. The aluminum construction offers advantages in weight reduction and ease of handling, particularly in long runs or outdoor installations where weather exposure is a consideration. It is suitable for many residential and commercial applications where flexibility and durability are priority.
Sealproof Weatherproof Aluminum LB Conduit Body – 2″
Sealproof’s weatherproof aluminum LB conduit body features a stamped aluminum cover and an NBR gasket, delivering a reliable watertight seal for outdoor conduit runs. The LB design enables a 90-degree change in direction, enhancing ease of installation where space constraints exist. The die-cast aluminum construction provides rust and corrosion resistance, supported by a premium powder-coated finish. It’s suitable for use with rigid or IMC conduit, and the removable cover aids in splicing, pulling, or maintenance activities, all while maintaining outdoor-grade protection.
Wocloer PVC Liquid-Tight Conduit – 2 Inch, 25 Feet
Wocloer’s 2-inch PVC liquid-tight conduit is a non-metallic option designed for tough outdoor environments. Made from high-quality virgin PVC, it resists corrosion, oil, and water while maintaining a smooth interior for easy wire pulling. The conduit features a UV-resistant jacket, ensuring longevity under sun exposure. This 25-foot length is suitable for longer outdoor runs, direct burial, or installations in harsh environments where metal conduits may pose corrosion concerns. It is notably lighter than metallic conduits, potentially reducing installation costs.
Buying Guide
Key considerations when selecting PVC-coated or aluminum conduit include: material and environmental suitability, flexibility and length, diameter and inner pulling space, weather resistance, and compliance with relevant standards. PVC-coated metal conduits are favored where moisture exposure and physical abrasion are concerns, offering leak resistance and smoother interiors. Aluminum conduits and conduit bodies provide lightweight strength and corrosion resistance, often aiding in long runs or outdoor installations. For non-metallic needs, PVC liquid-tight conduit offers moisture resistance and UV protection, with varying diameters to fit your wiring requirements. Ensure compatibility with your local electrical code and project specifications, including temperature range and outdoor exposure.
Diameter and length determine how many conductors you can pull and how easily you can route the cable. A larger diameter inside allows easier pulling, but may require larger fittings and more space in conduits. For outdoor or wet locations, look for water-proof seals, corrosion resistance, and corrosion-resistant finishes like powder coatings. If weight and ease of handling are important, aluminum conduits provide advantages over steel in long runs. Finally, consider whether you need a conduit body with access for splicing and maintenance; LB-type bodies offer convenient 90-degree transitions essential in tight spaces.
