3/4 in Threaded IMC Bushing

The Hubbell RACO 1403 is an insulating bushing designed for 3/4 in trade size RMC and IMC conduit. It provides a smooth, protected entry point for conductors passing through a threaded female NPT hub. The gray plastic body is UL 514B listed and rated for use with threaded fittings in commercial or residential electrical installations.

Plain Finish with Zinc-Plated Hardware

The bushing features a plain plastic finish in gray with zinc-plated components for corrosion resistance. Its female NPT threads accept standard 3/4 in -14 conduit or fittings, while the 0.78 in inside diameter accommodates conductor bundles without sharp edges. Overall height and width are each 1 9/32 in, and the 13/32 in overall length keeps the profile compact inside enclosures or boxes.

Verify Conduit Type and Thread Compatibility

Confirm that your raceway is RMC or IMC with a 3/4 in trade size and 3/4 in -14 NPT male threads before ordering. This bushing is not intended for non-threaded conduit systems such as EMT or PVC without appropriate adapters. Check that the 0.78 in inside diameter suits your conductor fill requirements and that the 13/32 in length fits your enclosure depth.

Questions about this item

What does the NPT 3/4-14 thread cap in practice?

The NPT 3/4-14 female thread accepts threaded RMC and IMC conduit fittings, providing an insulated entry point that meets UL 514B for 3/4 in trade-size conduit.

What physical space does the 1 9/32 in overall height and 13/32 in length require?

The bushing needs a 1 9/32 in diameter clearance and 13/32 in depth inside the enclosure or fitting to seat the 0.78 in inside-diameter throat fully.

How is the zinc-plated threaded bushing installed, and what step is often missed?

Thread the bushing onto the conduit until the shoulder bottoms out, then tighten the included clamp; the missed step is verifying the insulated throat seats squarely so conductors cannot contact bare metal threads.
