Thomas Betts TK213SC Emt Conduit Coupling 1 Inch

Product Description

The THOMAS BETTS TK213SC is a compression-style conduit coupling designed for use with electrical metallic tubing (EMT). It joins two sections of EMT conduit end-to-end, maintaining a continuous raceway without the need for set screws or tools beyond standard hand compression fittings. Made from die cast zinc, this coupling is rated for concrete-tight applications, making it suitable for installations where moisture or embedment resistance is required. The non-insulated design is standard for this fitting class. At 0.29 pounds, it is lightweight and straightforward to handle during rough-in work. Licensed electricians and conduit installers typically specify this fitting for commercial and residential wiring systems.

This coupling is used wherever EMT conduit runs require a secure, concrete-tight mechanical connection. Common applications include conduit runs through concrete slabs, masonry walls, and wet or damp-rated locations where a compression fitting provides superior ingress resistance compared to a set-screw type. It fits 1-inch trade size EMT and is sold as an individual piece, suited for both new construction and retrofit conduit work.

Key Features

• Compression connection type — no set screws required, secure mechanical fit
• Concrete-tight area of application rating for use in embedded or damp environments
• Die cast zinc construction for durability and corrosion resistance in standard conduit applications
• Non-insulated design matches standard EMT coupling specifications
• 1-inch trade size fits standard 1-inch EMT conduit sections

Compatibility

Designed as an OEM-style replacement or standard-fit coupling for 1-inch trade size EMT conduit systems in residential and commercial electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for conduit wiring methods. De-energize all circuits in the work area before beginning conduit assembly. Compression couplings are tightened by hand and then snugged with pliers or a strap wrench — do not overtighten, as die cast zinc fittings can crack under excessive force. Ensure conduit ends are cut cleanly and reamed before inserting into the coupling to maintain a proper compression seal.
