Thomas Betts TK211SC Emt Conduit Coupling 1/2 Inch

Product Description

The THOMAS BETTS TK211SC is a compression-style conduit coupling designed for use with 1/2 inch trade size EMT conduit. Constructed from die cast zinc, this coupling provides a concrete-tight, non-insulated connection between two sections of electrical metallic tubing. The compression connection method eliminates the need for set screws, delivering a secure mechanical bond that meets concrete-tight application requirements. Electricians rely on this fitting in commercial and residential rough-in work where conduit runs must be joined cleanly and securely within concrete encasements or similarly demanding environments.

This coupling is suited for 1/2 inch EMT installations in both residential and light commercial electrical work. It performs in concrete-encased conduit applications where a tight, moisture-resistant mechanical connection is required. The compression design allows for straightforward assembly during conduit rough-in, making it a standard choice for electricians pulling EMT runs through slabs, walls, or other structural elements where fitting integrity is critical.

Key Features

• Compression connection type — no set screws required for a secure mechanical joint
• Concrete-tight rating suitable for encased conduit installations
• Die cast zinc construction for durability in standard electrical conduit applications
• Non-insulated fitting for direct metallic continuity through the coupling
• 1/2 inch trade size for compatibility with standard EMT conduit

Compatibility

Designed as an OEM-style replacement and standard-use coupling for 1/2 inch trade size EMT conduit systems in residential and commercial electrical installations.

Installation Notes

Installation is performed by a licensed electrician following applicable NEC requirements for EMT conduit systems. Ensure all power to the circuit is de-energized before working on any conduit run. The compression nut should be tightened firmly by hand and then snugged with pliers or a strap wrench — do not overtighten, as die cast zinc fittings can crack under excessive force. Verify concrete-tight integrity before encasement when used in poured concrete applications.
