Bridgeport Fittings 1121 3-piece Conduit Coupling 1/2 Inch

Product Description

The BRIDGEPORT FITTINGS 1121 is a three-piece malleable iron conduit coupling designed to join two lengths of threaded rigid or IMC conduit. Zinc-electroplated for corrosion resistance, this concrete-tight, heavy-duty coupling delivers impact-resistant performance in demanding environments. Its malleable iron construction provides strong fracture toughness, making it well suited for installations where conduit is subject to crushing, abrasion, or physical stress. Licensed electricians and electrical contractors install this fitting wherever code requires a durable, secure connection between rigid metal conduit sections.

This coupling is used in commercial and industrial electrical installations where rigid conduit or IMC runs require a reliable threaded connection. Its concrete-tight rating makes it appropriate for embedded or surface-mounted conduit runs in concrete and masonry environments. The three-piece design simplifies assembly in tight spaces where spinning a standard coupling along the full conduit run is not practical.

Key Features

• Three-piece design allows installation without rotating conduit sections
• Malleable iron construction resists impact, crushing, and abrasion
• Zinc electroplate finish provides corrosion resistance
• Concrete-tight rated for embedded and exposed conduit applications
• Threaded ends compatible with rigid metal conduit and IMC

Compatibility

Designed as an OEM-style replacement fitting for 1/2 inch threaded rigid metal conduit and IMC conduit systems in standard 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. Use appropriate pipe wrenches or conduit tools to achieve a secure threaded connection without over-torquing the malleable iron body. Verify the concrete-tight rating meets the requirements of the installation environment before use.
