Thomas Betts 5121-TB Emt Conduit Connector 1/2 Inch

Product Description

The THOMAS BETTS 5121-TB is a straight, compression-style conduit connector designed for use with 1/2 inch trade size EMT (electrical metallic tubing). Constructed from steel with a non-insulated design, this connector forms a concrete-tight, water-resistant termination where EMT meets an enclosure, junction box, or panel knockout. Compression fittings require no setscrew and deliver a secure, consistent connection that meets the demands of commercial and residential electrical installations. Licensed electricians and electrical contractors install this fitting wherever code requires a reliable EMT termination.

This connector is suited for indoor and outdoor electrical raceway systems where concrete-tight and water-resistant performance is required. Common applications include conduit runs entering electrical panels, junction boxes, and enclosures in commercial buildings, industrial facilities, and residential construction. The compression connection method is favored in installations where vibration resistance and a clean, tool-free tightening process are priorities. It accepts 1/2 inch trade size EMT, the most commonly used conduit size in light commercial and residential wiring.

Key Features

• Compression connection provides a concrete-tight, water-resistant seal without setscrews
• Straight connector shape for direct EMT-to-enclosure termination
• Steel construction for durability in demanding installation environments
• Non-insulated design compatible with standard EMT termination methods
• Rated for concrete-tight and water-resistant applications
• 1/2 inch trade size fits the most common EMT conduit diameter used in the field

Compatibility

Designed as an OEM-style compression connector for use with 1/2 inch trade size EMT conduit in standard electrical raceway installations.

Installation Notes

Installation is performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the panel or enclosure before making any conduit terminations. Thread the compression nut onto the EMT end, insert the conduit through the fitting body, and tighten the compression nut hand-tight plus a quarter turn with pliers to achieve the concrete-tight rating. Do not overtighten, as this can deform the fitting or conduit end and compromise the seal.
