Bridgeport Fittings 3600 Set Screw Coupling 1/2 in Malleable Iron

Product Description

The BRIDGEPORT FITTINGS 3600 is a 1/2-inch set screw coupling designed to join two lengths of unthreaded rigid or IMC conduit in a concrete-tight application. Constructed from zinc-plated malleable iron, this coupling provides a durable, corrosion-resistant connection suited for demanding electrical installation environments. The coupling measures 1.75 inches in length and 0.75 inches in diameter, making it a compact, reliable fitting for standard 1/2-inch conduit runs. Licensed electricians and electrical contractors install this fitting where a concrete-tight rating is required, such as conduit embedded in concrete or run through masonry assemblies.

This coupling is used in residential and commercial electrical installations where rigid metal conduit or IMC conduit must be joined without threading. It is well suited for applications where the conduit run passes through or is encased in concrete, and where a secure, tight mechanical connection is required by code. The set screw design eliminates the need for threaded conduit ends, simplifying installation in the field.

Key Features

• Concrete-tight rated for conduit runs embedded in or passing through concrete
• Set screw design joins unthreaded rigid or IMC conduit without threading
• Zinc-plated malleable iron construction for corrosion resistance and durability
• Compact profile at 1.75 inches long and 0.75 inches in diameter
• Fits standard 1/2-inch rigid and IMC conduit

Compatibility

Designed as an OEM-style fitting for use with standard 1/2-inch unthreaded rigid metal conduit and intermediate metal conduit in concrete-tight installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits in the affected conduit run before making or breaking conduit connections. Insert both conduit ends fully into the coupling and tighten the set screws securely to achieve the concrete-tight rating. Verify that the conduit ends are clean and free of burrs before assembly to ensure a proper fit.
