Thomas Betts TK223SC Emt Conduit Coupling 1 Inch

Product Description

The THOMAS BETTS TK223SC is a set screw conduit coupling designed for use with electrical metallic tubing (EMT). It provides a secure, non-insulated mechanical connection between two sections of 1-inch trade size EMT conduit. Constructed from die cast zinc, this coupling is rated for concrete-tight applications, making it suitable for installations where the conduit may be embedded in or run along concrete surfaces. Licensed electricians and electrical contractors install this fitting as a standard part of EMT raceway systems in both new construction and retrofit work.

This coupling is intended for 1-inch trade size EMT conduit systems in residential, commercial, and light industrial electrical installations. The set screw connection method allows for straightforward field installation without specialized tooling. Its concrete-tight rating makes it appropriate for use in slab pours, concrete walls, and similar embedded or surface-mounted conduit runs where moisture and debris resistance at the joint is required.

Key Features

• Set screw connection type for secure mechanical coupling without threading
• Die cast zinc construction provides durability and corrosion resistance suitable for concrete-tight environments
• Concrete-tight area of application rating
• Non-insulated design for standard EMT raceway use
• 1-inch trade size fits standard 1-inch EMT conduit

Compatibility

Designed as an OEM-style replacement and standard fitting for 1-inch trade size EMT conduit systems requiring a set screw coupling with concrete-tight performance.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements and local electrical codes. De-energize all circuits in the affected raceway before beginning work. Use an appropriate set screw driver or hex key to tighten the set screws to secure the coupling; do not overtighten, as this can damage the die cast zinc body. Verify the concrete-tight integrity of the joint before encasement if embedding in concrete.
