Cooper Crouse-Hinds LB25 Condulet Series 5 Conduit Outlet Body
Overview
The Cooper Crouse-Hinds LB25 is a Condulet Series 5 conduit outlet body engineered for rigid, intermediate metal conduit (IMC), and EMT raceway systems that require a reliable pull point, splice access, or direction change without disturbing conductor insulation. Sized for 3/4-inch trade conduit with a 7.3 cubic-inch internal capacity, the LB25 is a Type LB body – meaning the hub outlet exits from the back of the fitting, making it the standard choice wherever a conduit run must turn a corner tight against a wall, panel, or structural member while still leaving room to pull heavy-gauge conductors through cleanly.
As the official authorized partner and exclusive regional representative for Cooper Crouse-Hinds, Seven Star LLC proudly supplies the LB25 Condulet Series 5 conduit outlet body to contractors, EPC firms, and plant maintenance teams across the Sultanate of Oman and the wider GCC. Every unit shipped from our Muscat-based warehouse is genuine Crouse-Hinds stock, backed by full manufacturer traceability and technical support – assurance that matters when specifying conduit systems for refinery, desalination, and district cooling projects where substituted or counterfeit fittings are not an acceptable risk.
Operating Principle
A conduit outlet body such as the LB25 is a passive mechanical enclosure rather than an active device, but its geometry still governs how conductors are protected and how the raceway system behaves electrically and mechanically. The two threaded hub openings carry NPT tapered threads with integral bushings that shield wire insulation from abrasion as conductors are pulled through the casting, while the interior radius of the LB body is sized to respect the minimum bend radius required by code for the conductor sizes the fitting is rated to carry. Because the body is a sealed, code-compliant enclosure once its gasketed cover is installed, it also functions as a legal splice and tap point – conductors can be joined, tapped, or simply pulled straight through without the raceway losing its mechanical continuity or its protection against dust and moisture ingress.
The practical consequence of this design is a maintenance-friendly access point that requires no special tools beyond a standard screwdriver to open, inspect, or re-pull conductors, and that introduces no moving parts to wear out over the life of the installation. Because the LB25 is rated NEMA 4, the gasketed cover also maintains a degree of protection against windblown dust and splashing water, which is a meaningful advantage on outdoor conduit runs across coastal and desert sites in Oman where sand ingress and occasional heavy rain both threaten unprotected junctions.
Engineering Design of the Cooper Crouse-Hinds LB25
The LB25 body is die cast from copper-free aluminum, a material chosen specifically for conduit systems because it eliminates the risk of galvanic corrosion that copper-bearing alloys can trigger when conduit runs pass near dissimilar metals or in humid, saline environments – a common condition along Oman’s coastal industrial corridors including Sohar and Salalah. The casting is then finished with an epoxy powder coat that adds a further corrosion-resistant barrier over the aluminum substrate while giving the fitting a durable gray finish that resists chipping during transport and installation.
Physically, the LB25 measures 4.97 inches in length, 1.53 inches in width, and 2.38 inches in height, with two 3/4-inch hub openings positioned for the classic LB back-outlet configuration. The body ships complete with hubs and tri-head set screws for securing conduit runs, and the flat gasket-sealing surface on the open face accepts the corresponding Crouse-Hinds Form 5 cover plate to close the enclosure once conductors are pulled and terminated. The fitting is listed to UL File No. E-15022 and cUL certified, and it is manufactured to meet NEC/CEC installation requirements as well as the Buy American Act and RoHS compliance standards that many Gulf-region EPC specifications now reference for imported electrical materials.
Key Features
The Cooper Crouse-Hinds LB25 combines a compact footprint with genuine field-proven durability, and the following features summarize why it remains a specified standard on industrial and commercial conduit systems throughout Oman and the GCC.
- Die-cast copper-free aluminum body construction resists galvanic corrosion and keeps installed weight low on long conduit runs.
- Epoxy powder coat finish provides an additional corrosion-resistant layer suited to coastal, industrial, and high-humidity environments.
- 3/4-inch trade size hubs with 7.3 cubic-inch internal capacity accommodate standard rigid, IMC, and EMT conduit systems.
- Type LB back-outlet configuration allows tight 90-degree direction changes against walls, panels, and structural steel.
- Tapered NPT threads with integral bushings on both hubs protect conductor insulation during installation and future re-pulls.
- NEMA 4 rated gasketed cover interface (Form 5 cover, ordered separately) resists dust and water ingress on outdoor and washdown-adjacent runs.
- Ships complete with hubs and tri-head set screws, reducing field assembly time and material take-off complexity.
- UL Listed and cUL certified to UL File No. E-15022, satisfying NEC/CEC code requirements referenced across regional EPC specifications.
Industrial Applications
The LB25 is specified wherever a 3/4-inch rigid or IMC conduit run needs to change direction, provide a pull point, or create a legal splice location without exceeding the conductor fill and bend-radius limits set by code. Typical placements include motor control wiring in pump houses, lighting and small power circuits in process areas, instrumentation conduit runs feeding field transmitters, and panel-to-panel conduit routing in electrical rooms where space behind switchgear is limited and a compact back-outlet body is the only geometry that fits.
As the officially authorized partner for Cooper Crouse-Hinds, Seven Star LLC distributes the LB25 Condulet Series 5 conduit outlet body to EPC contractors and maintenance departments across oil and gas facilities, RO desalination plants, district cooling stations, and commercial developments throughout Muscat, Sohar, and Salalah, as well as the broader GCC. Our regional stock holding and authorized supply chain mean that specifiers and site engineers can source genuine LB25 fittings on short lead times, without the compliance risk that comes from unverified grey-market imports on projects where UL listing and manufacturer traceability are mandatory contract requirements.
