Thomas Betts TK222SC Emt Conduit Coupling 3/4 in

Product Description

The THOMAS BETTS TK222SC is a set screw conduit coupling designed for use with electrical metallic tubing (EMT). Made from die cast zinc, this coupling joins two sections of 3/4 inch trade size EMT conduit in a secure, non-insulated connection. It is rated for concrete tight applications, making it suitable for installations where the coupling may be embedded in or in contact with concrete. Licensed electricians and electrical contractors install this fitting during new construction and retrofit wiring projects.

This coupling is used in commercial and residential electrical installations wherever 3/4 inch EMT conduit runs require a rigid, reliable joint. Its concrete tight rating suits slab pours, below-grade encasements, and other applications where moisture and debris contact is a concern. The set screw connection method provides a mechanically secure fit without requiring specialized tools beyond a standard screwdriver or nut driver.

Key Features

• Set screw connection for tool-accessible, mechanically secure conduit joints
• Die cast zinc construction provides durability and corrosion resistance in concrete tight environments
• Non-insulated design suitable for standard grounded EMT systems
• Concrete tight rated for embedded or exposed installations
• 3/4 inch trade size fits standard 3/4 inch EMT conduit

Compatibility

Designed as an OEM-style fitting for use with 3/4 inch trade size EMT conduit systems in standard electrical raceway installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits in the conduit run before making connections. Tighten set screws firmly using a flathead screwdriver or appropriately sized nut driver to ensure mechanical integrity and proper grounding continuity. Verify the coupling is rated for the specific application environment before embedding in concrete or installing in wet locations.
