Thomas Betts TK214SC Emt Conduit Coupling 1-1/4 in

Product Description

The THOMAS BETTS TK214SC is a compression-style conduit coupling designed for use with electrical metallic tubing (EMT). It provides a secure, concrete-tight connection between two sections of EMT conduit without requiring tools for the initial fitting. Made from die cast zinc, this coupling resists corrosion and delivers the mechanical strength required in demanding installation environments. The non-insulated design suits standard raceway applications where a metal-to-metal bond is required. At 1-1/4 inch trade size, it fits directly into common commercial and residential wiring installations. Licensed electricians and journeymen are the primary installers of this fitting.

This coupling is suited for use in concrete encasement applications where a concrete-tight rating is required. It is appropriate for both commercial and residential electrical installations where EMT is the specified raceway. The compression connection eliminates the need for set screws, providing a uniform grip around the conduit. It is commonly installed in exposed or embedded conduit runs where a reliable mechanical and electrical bond between conduit sections is essential.

Key Features

• Compression connection type provides tool-free, uniform conduit grip
• Concrete-tight area of application rating for embedded conduit runs
• Die cast zinc construction for corrosion resistance and mechanical durability
• Non-insulated design for standard metal-to-metal raceway continuity
• 1-1/4 inch trade size fits standard EMT conduit of the same trade size

Compatibility

Designed as an OEM-style replacement and standard fitting for 1-1/4 inch trade size EMT conduit systems in residential and commercial electrical raceway applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits in the affected raceway before making or breaking conduit connections. Ensure conduit ends are cut square and deburred before seating into the coupling to maintain a proper compression seal. For concrete-tight applications, verify the fitting is fully seated and the compression nut is hand-tightened before encasement.
