Thomas Betts 8324-TB Conduit Coupling 1 in Rigid Imc

Product Description

The THOMAS BETTS 8324-TB is a steel conduit coupling designed for joining rigid metal conduit and intermediate metal conduit (IMC) runs in electrical installations. It uses a set screw connection method for a secure, non-insulated mechanical bond between conduit sections. Rated for concrete-tight applications, this coupling is built for use in commercial and industrial environments where conduit must be protected against moisture infiltration and physical damage. Electricians rely on this fitting when extending or joining conduit runs during rough-in work on new construction or retrofit projects.

This coupling is suited for 1-inch trade size rigid and IMC conduit installations in both residential and commercial electrical work. Concrete-tight construction makes it appropriate for installations embedded in or running along concrete surfaces, including slab, wall, and ceiling applications. The set screw design allows for straightforward installation without threading tools, making it a practical choice for field assembly where speed and reliability are both priorities.

Key Features

• Set screw connection for tool-accessible, secure field assembly
• Concrete-tight construction suitable for embedded and exposed concrete applications
• Non-insulated steel body provides mechanical strength and durability
• Compatible with both rigid metal conduit and intermediate metal conduit (IMC)
• 1-inch trade size fits standard conduit in that diameter class

Compatibility

Designed for use with 1-inch trade size rigid metal conduit and intermediate metal conduit (IMC) in standard electrical raceway systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for conduit fittings. De-energize all circuits in the work area before beginning conduit work. Tighten set screws using the appropriate hex key or screwdriver to ensure a secure mechanical connection. Verify that concrete-tight integrity is maintained at each coupling point when embedding conduit in poured concrete.
