Thomas Betts 8224 Steel Conduit Coupling 3/4 Inch Imc Rigid

Product Description

The THOMAS BETTS 8224 is a steel set screw conduit coupling designed to join sections of rigid metal conduit (RMC) and intermediate metal conduit (IMC) in electrical raceway installations. The coupling uses a set screw connection method for a secure, non-insulated mechanical joint. Rated for concrete-tight applications, this fitting is suited for embedded or exposed runs where a reliable, low-profile coupling is required. Licensed electricians and electrical contractors install this fitting as part of standard metallic conduit systems in commercial and industrial environments.

This coupling is appropriate for use in rigid and IMC conduit systems at the 3/4 inch trade size. Its concrete-tight rating makes it suitable for installations where conduit is embedded in concrete or where similar environmental protection is needed. The set screw design allows for straightforward installation with standard hand tools and does not require threaded conduit ends, making it compatible with common field-assembly practices on new construction and retrofit electrical projects.

Key Features

• Set screw connection method — no threading required on conduit ends
• Steel construction for durability in metallic conduit systems
• Concrete-tight area of application rating
• Non-insulated design for standard metallic conduit bonding continuity
• 3/4 inch trade size fits standard RMC and IMC conduit of the same trade size

Compatibility

Designed for use with 3/4 inch trade size rigid metal conduit (RMC) and intermediate metal conduit (IMC) systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the conduit run before beginning work. Tighten set screws to secure the coupling to each conduit end using an appropriately sized hex key or screwdriver; do not overtighten to the point of deforming the conduit wall. Verify concrete-tight integrity before encasement when used in poured concrete applications.
