Thomas Betts TK215SC Emt Conduit Coupling 1-1/2 in

Product Description

The THOMAS BETTS TK215SC is a compression-style conduit coupling designed for use with electrical metallic tubing (EMT). It connects two sections of EMT conduit in a secure, concrete-tight fit without the need for set screws. The die cast zinc body provides solid mechanical strength and corrosion resistance for standard electrical installations. At 1-1/2 inch trade size, this coupling is suited for medium-to-large conduit runs in commercial and residential wiring systems. Installation requires only basic hand tools to compress the fitting into position. Licensed electricians and qualified electrical contractors are the primary installers.

This coupling is commonly used in commercial and industrial electrical installations where EMT conduit is routed through or embedded in concrete. The concrete-tight rating makes it appropriate for slab-embedded conduit runs, where moisture and aggregate intrusion must be prevented. It is also used in exposed conduit applications in mechanical rooms, utility spaces, and above-ceiling wiring environments. Non-insulated construction is standard for this fitting type, consistent with NEC requirements for metallic conduit systems where the conduit itself serves as the equipment grounding conductor.

Key Features

• Compression connection — no set screws required for secure conduit-to-conduit joining
• Concrete-tight rated — suitable for slab-embedded and wet-location EMT installations
• Die cast zinc body — provides durable, corrosion-resistant construction
• 1-1/2 inch trade size — fits standard 1-1/2 inch EMT conduit
• Non-insulated design — compatible with standard metallic conduit grounding practices

Compatibility

Designed as an OEM-style compression coupling for 1-1/2 inch EMT conduit systems in residential, commercial, and light industrial electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the conduit run before beginning work. Compression fittings require a conduit wrench or pliers to achieve proper compression on the ferrule — do not over-tighten to the point of cracking the zinc body. For concrete-embedded applications, confirm that the fitting is rated for direct burial or encasement before pouring.
