  • Electroplated steel resists corrosion in demanding industrial environments
  • Compact 13/16 in height fits tight junction boxes and enclosures
  • Lightweight .07 lb design simplifies handling and installation overhead

Conduit Reducer for IMC and Threaded RMC

This reducing bushing connects 1/2 inch and 3/4 inch conduit sizes in hazardous-location installations. It provides a female-to-male thread transition between 1/2 inch FNPT and 3/4 inch MNPT ends. The steel body carries an electroplated finish for corrosion resistance. It is listed for use with both IMC and threaded rigid metal conduit.

Suited for Hazardous-Area Conduit Transitions

Installers joining different trade sizes in classified areas will find the correct thread configuration here. The fitting is not intended for non-threaded conduit systems or for environments that do not require hazardous-location ratings. Buyers needing a straight coupling or a different thread combination should select another fitting.

Overall Length 3/4 in

The bushing measures 3/4 inch in overall length, a critical dimension for calculating conduit run allowances in tight enclosures. This length determines how much thread engagement is available on each side. Verify the measurement against your layout before ordering.

Questions about this item

Does the 13/16 in height and 1 1/16 in width let this bushing sit flush inside a standard 3/4 in knockout?

The overall height is 13/16 in and overall width 1 1/16 in, so the hex body fits a typical 3/4 in knockout without protruding past the box wall.

Will the 1/2 in FNPT female threads accept the 1/2 in RMC conduit I already have installed?

Yes, the female end is 1/2 in FNPT and the spec lists compatible conduit types as IMC and threaded RMC in both 1/2 in and 3/4 in trade sizes.

After tightening, how can I confirm the electroplated steel finish is making proper metal-to-metal contact for grounding?

With the bushing fully threaded, the steel body should sit tight against the enclosure and conduit; a continuity tester across the joint will verify the electroplated path.
