SEPCO LB47 4-Inch Type LB Sand-Cast Copper-Free Aluminum Conduit Body

The SEPCO LB47 is a Type LB conduit outlet body built from sand-cast, copper-free aluminum for 4-inch trade size conduit systems. Its LB-style body creates a 90° access point along the conduit run, giving electricians room to pull, splice, and redirect conductors without disturbing the surrounding raceway. A removable cover on the body allows access to conductors for maintenance or future wiring changes while keeping the enclosure protected when closed. Sand-cast, copper-free aluminum construction keeps the SEPCO LB47 corrosion-resistant and job-site durable while remaining lighter than comparable cast-iron conduit bodies, making it a practical choice for large-diameter 4-inch conduit installations.

Key Features

  • Trade Size: Sized for 4-inch trade size conduit, suitable for large-diameter conduit runs.
  • Durable Construction: Sand-cast, copper-free aluminum body resists corrosion and holds up to demanding job-site conditions.
  • Type LB Configuration: LB-style outlet body provides a 90° access point for pulling and splicing conductors without breaking down the conduit run.
  • Copper-Free Alloy: Copper-free aluminum composition helps reduce the risk of galvanic corrosion where the fitting contacts dissimilar metals.
  • Sand-Cast Body: Sand-cast manufacturing produces a thick-walled, rugged body designed for a long service life.
  • Removable Access Cover: Removable cover plate provides straightforward access to conductors for pulling, splicing, or future modifications.
  • Lightweight Aluminum Body: Aluminum construction reduces overall fitting weight compared to iron bodies, easing installation of large 4-inch conduit runs.

SEPCO LB7A – Frequently Asked Questions

1) What trade size conduit does the SEPCO LB47 LB conduit body fit?
The LB47 is built for 4 inch trade size conduit, which is the top end of standard rigid and IMC runs. If your run is smaller, you need the matching smaller trade size body, not this one, since the hubs are fixed at 4 inch.
2) What is the difference between the SEPCO LB47 LB conduit body and an Ocal Form 7 PVC-coated LB body?
They differ in material and coating. The SEPCO LB47 is a sand-cast, copper-free aluminum Type LB conduit body with a 90 degree access point, sized for 4-inch trade size conduit. The Ocal Form 7 LB conduit body is iron with a PVC coating. The copper-free aluminum of the LB47 resists corrosion through its alloy and is lighter than iron, while the Ocal relies on a bonded PVC jacket over an iron body. Specify the PVC-coated iron where a coated raceway system is called out on the drawings and the coating must be continuous through the fitting; use the aluminum LB47 where an uncoated large-diameter run needs a lightweight pull and splice point.
3) What LB conduit body should I use instead of the SEPCO LB47 on a PVC-coated conduit system?
Use a PVC-coated LB body so the coating stays continuous through the fitting. The Ocal Form 7 PVC-coated LB conduit body is an iron body with a PVC coating, and the Ocal LB17-G Series LB-shape conduit body is also a Form 7 product. The SEPCO LB47 is sand-cast copper-free aluminum with no coating, so it is the fitting for bare rigid or IMC runs rather than a coated raceway system.
4) Why use a Type LB body instead of a Type C or Type T on a 4 inch conduit run?
A Type LB turns the run 90 degrees with the access opening on the back, so it is what you use where conduit comes out of a wall and heads down (or up) with a pull point right at the turn. A Type C is a straight-through pull body with no change of direction, and a Type T gives you a third opening for a branch. Pick the LB47 when you need both the 90 degree turn and conductor access at the same point.
5) Does the LB47 come with a cover, or do I order the cover separately?
A removable access cover is part of the LB47 body. You pull the cover to pull, splice, or re-pull conductors, then close it back up to protect the enclosure. Gasket and sealing accessories for the opening are separate items.
6) Can I use the SEPCO LB47 as a wire pulling point on a long rigid conduit run?
That is the normal use. The LB body opens a 90 degree access point along the run so conductors can be pulled, spliced, or redirected without breaking down the surrounding raceway, and it is listed by SEPCO for rigid and IMC conduit routing and for wire pulling and splicing access.
7) Is an aluminum 4 inch conduit body easier to handle overhead than a cast iron one?
Yes. At 4 inch trade size the fitting itself is heavy, and the aluminum body weighs less than a comparable cast-iron conduit body, which is why SEPCO points to it for large-diameter runs. That matters most on strut or overhead work where one electrician is holding the body while the run is made up.
