Bridgeport Fittings 3100 Compression Coupling 1/2 Inch

Product Description

The BRIDGEPORT FITTINGS 3100 is a screw-on compression coupling designed to join two lengths of unthreaded rigid or IMC conduit without threading the conduit ends. The steel construction provides durability in standard non-acidic environments, and the compression design eliminates the need for tape or thread sealant to achieve a secure, concrete-tight connection. This coupling is listed to UL Standard UL-514B, confirming it meets established requirements for conduit fittings used in electrical installations. Licensed electricians and electrical contractors install this fitting in new construction and retrofit work where rigid conduit runs require a mid-run coupling.

This fitting is suited for use in commercial and residential electrical conduit systems where rigid metal conduit or IMC is specified. It is appropriate for applications requiring a listed compression-style coupling that does not depend on threaded conduit ends, making it practical on job sites where pre-cut conduit lengths need to be joined quickly and reliably without additional sealing materials.

Key Features

• Screw-on compression design — no tape or thread sealant required to achieve a tight connection
• Joins two lengths of unthreaded rigid or IMC conduit
• Steel construction for durability in standard non-acidic environments
• Listed to UL Standard UL-514B for conduit and conduit fittings
• 1/2 inch trade size for use with 1/2 inch rigid conduit

Compatibility

Designed as an OEM-style compression coupling for use with 1/2 inch unthreaded rigid metal conduit and IMC conduit systems.

Installation Notes

Installation is performed by licensed electricians in accordance with NEC requirements for rigid metal conduit systems. De-energize the circuit and verify power is off before working on any conduit assembly. Slide the coupling over the conduit ends and tighten the compression nut by hand before applying final torque with appropriate hand tools. Do not use this fitting with conduit types or trade sizes other than those specified.
