Below are five top picks for 2-inch rigid conduit applications, each with practical considerations for installation, durability, and compatibility with common conduit systems.
Sealproof LB Conduit Body With Threaded Hubs

Sealproof’s LB conduit body combines a durable die-cast aluminum body with a powder-coated finish, delivering rust and corrosion resistance for outdoor or harsh environments. The LB design enables a 90-degree turn, simplifying pulling, splicing, and maintenance of wiring in tight spaces. A stamped aluminum cover plus a synthetic rubber gasket ensure a watertight seal, supporting reliable operation across weather conditions. This unit is suitable for rigid or IMC conduit systems and provides straightforward access to the interior raceway for routine inspections.
COREX 2″ LB Format Threaded Rigid Conduit Body

This COREX LB-format conduit body is crafted from malleable iron, offering robust mechanical protection for high-demand installations. It includes a cover and gasket setup designed for a secure, durable seal in outdoor or corrosive environments. The LB body’s 90-degree access improves ease of wiring work within the raceway, and the sturdy construction helps endure vibration and physical impact in industrial settings.
Leviton Watertight Conduit Hub, 2-Inch

Leviton’s 2-inch watertight conduit hub is designed for IMC or rigid conduit systems with a threaded connection. Die-cast zinc hubs provide reliable grounding with insulated throats to prevent wire abrasion. An embedded O-ring seals the junction, protecting against moisture intrusion in outdoor or damp locations. This hub supports secure, long-term connections in exposed installations and helps maintain electrical integrity in challenging environments.
SIGMA ProConnex 02-55646LB Rigid Type LB Body

The Sigma ProConnex LB body is designed for 2-inch rigid conduit or IMC, featuring a removable aluminum cover and a rubber gasket for interior access. This unit pre-assembles with a stamped cover, enabling straightforward serviceability. The LB body design supports clean changes in conduit direction while maintaining a sturdy enclosure for splices and terminations within the raceway.
SIGMA ProConnex 2-Inch Locknut (2-Pack)

These 2-inch ProConnex locknuts provide secure threaded connections for 2″ rigid conduit, IMC, and other threaded fittings. The two-pack offers a practical option for ensuring consistent grip and dependable performance across multiple joints in a system. Easy installation and reliable locking contribute to stable electrical assemblies in both residential and commercial projects.
Buying Guide: Key Purchase Considerations For 2-Inch Rigid Conduit Fittings
- Material and durability: Choose materials suited to the environment (die-cast aluminum, malleable iron, or zinc) to balance corrosion resistance, strength, and weight. Outdoor installations benefit from gasketed seals and weatherproof designs.
- Conduit compatibility: Confirm compatibility with rigid and IMC conduits. For LB bodies, ensure smooth interior access for pulling and splicing in tight spaces.
- Sealing and water resistance: Look for integrated gaskets, O-rings, and gasketed covers to maintain a watertight seal in wet or outdoor conditions.
- Ease of installation: Consider products with pre-assembled covers or easy access designs. Locknuts and hubs should provide straightforward tightening without specialized tools.
- Maintenance and serviceability: Removable covers and accessible interiors simplify inspections, repairs, and upgrades over the life of the system.
- Regulatory compliance: UL-listed or equivalent listings indicate adherence to safety standards, which is important for electrical code compliance.
- Cost and availability: For ongoing projects, balance initial price against durability and warranty coverage. Availability in multiple pack sizes can reduce downtime.
- Installation environment: For coastal or corrosive environments, prioritize corrosion-resistant finishes and protective coatings to extend service life.
- Seal integrity: Ensure gaskets and grommets maintain integrity under temperature fluctuations and UV exposure when installed outdoors.
Technical Considerations At A Glance
LB conduit bodies provide convenient access points when routing through 90-degree turns, minimizing complex pull work. Hubs and locknuts offer reliable, threaded connections that resist loosening under vibration. For wet locations, enclosures with integral gaskets and watertight seals help prevent moisture ingress and corrosion. In some scenarios, metal versus non-metallic options present trade-offs in weight, ease of handling, and resilience to environmental factors.
When selecting 2″ fittings, assess the specific project needs: type of conduit (rigid vs IMC), exposure to weather, desired ease of maintenance, and the level of mechanical protection required. The right combination of LB bodies, hubs, and locknuts will provide a durable, code-compliant pathway for power distribution in commercial, industrial, or residential installations.
