Sealproof Weatherproof LB Conduit Body
The Sealproof LB conduit body is cast from durable aluminum with a powder-coated finish for rust and corrosion resistance. Its LB design enables a 90-degree turn in conduit runs, which helps reduce pulling strain and simplifies routing. A stamped aluminum cover and a gasket provide a watertight seal suitable for outdoor conditions. This product is best for outdoor builders and installers who need reliable weatherproof performance and a straightforward pull point. Caution: check seal integrity after long outdoor exposure to ensure gasket remains effective.
SIGMA ENGINEERED SOLUTIONS ProConnex 02-55841LB
The ProConnex 02-55841LB is a set screw Type LB for 3/4-in EMT conduit. It features a removable aluminum cover that allows access to the interior of the raceway. This design helps users perform pulling and splicing with ease. It is best for installers who prioritize straightforward interior access and a tool-secured connection. Choose this if you want a reusable access point that can be opened without disassembling the entire run. Limitation: set-screw type requires periodic tightness checks to maintain gasket pressure.
TayMac RLB075 LB Conduit Body
The TayMac RLB075 LB Conduit Body features durable die-cast aluminum construction with a premium powder coat finish and an NBR rubber gasket for a sealed, weather-resistant connection. It supports 3/4-inch conduit runs and is well-suited for outdoor or exposed installations where corrosion resistance is a priority. Best for projects needing a robust enclosure with a 90-degree pull point. Caution: ensure gasket seating is intact after exposure to extreme temperatures to prevent leaks.
Sigma Engineered Solutions ProConnex 02-55642LB
The ProConnex 02-55642LB is a rigid Type LB conduit body designed for 3/4-in conduit and IMC. It includes a removable aluminum cover for interior access and uses aluminum die-cast construction for durability. This option is best for installations requiring compatibility with rigid or IMC conduit. Choose this if you need a reliable pull point that works across different conduit types. Limitation: compatibility note—verify your conduit type before selecting if IMC is not part of your system.
Morris 14151 EMT LB Conduit Body
The Morris 14151 is an EMT set screw conduit body in Type LB with a 3/4-inch thread size, bundled as a 5-pack. It includes a cover and gasket, making it convenient for larger projects that require multiple access points along a run. Best for maintenance-heavy installations or when budgeting for multiple pull points. Caution: the set screw design requires routine checks to maintain a weather-tight seal over time.
Buying Guide
What is an LB conduit body and why choose it?
LB conduit bodies provide a 90-degree turn in conduit runs with access ports for pulling, splicing, and maintenance. They are common in both indoor and outdoor electrical installations where space constraints or configuration demands a sharp turn.
Material and finish considerations
Aluminum LB conduit bodies offer lightweight durability and corrosion resistance, making them suitable for outdoor use. Powder-coated finishes add an extra layer of protection against rust. When selecting, consider the environment and exposure to moisture, chemicals, or salt air.
Access method: set screws vs. removable covers
Set screw types are easy to secure and reuse but require regular tightening checks. Removable covers provide straightforward interior access for pulling and maintenance, but ensure the cover seals properly to prevent leaks.
Conduit compatibility
Most 3/4-inch LB conduit bodies support EMT, with some models also compatible with IMC or rigid conduit. Verify your conduit type before purchasing to ensure compatibility and a proper fit with your system.
Weather sealing and gasket considerations
Gaskets made from NBR rubber help create a watertight seal. Outdoor installations demand a reliable gasket to prevent moisture ingress, which can affect electrical performance and safety.
Installation and maintenance notes
Proper torque on set screws and correct gasket seating are essential for long-term performance. Periodically inspect seals and hardware, especially after temperature fluctuations or exposure to harsh weather.
Frequently Asked Questions
- What is the difference between LB and other conduit body types?
LB conduit bodies provide a 90-degree turn with access ports, while other types offer different access points or orientations for pulling conductors.
- Can I use 3/4-inch LB conduit bodies with IMC conduit?
Yes, some models are designed for IMC, but verify product specifications to ensure compatibility.
- Which material is best for outdoor use?
Aluminum with a powder-coated finish is typically best for outdoor exposure due to corrosion resistance.
- Do all LB conduit bodies include a gasket?
Most do, but always check the product details to confirm gasket presence and type.
- When should I choose a removable cover over a set screw design?
Removable covers are advantageous when interior access is frequent, while set screws are fine for fewer access points but require maintenance checks.
- What maintenance is required for these conduit bodies?
Regularly inspect seals, ensure screws are tight, and replace gaskets if signs of wear or cracking appear.
