  • TypeCable Management & Conduit
  • Reduces conduit size from 3/4 in to 1/2 in for flexible installations

Purpose and Audience

This reducing bushing adapts threaded rigid metal conduit from three-quarter inch to half inch trade size. It is intended for electricians and installers who need to transition conduit runs in commercial or industrial wiring projects.

Critical Specification

The fitting provides a female three-quarter inch NPS thread to a male half inch NPS thread with an overall length of nine sixteenths inch. This exact thread conversion determines whether the bushing matches the conduit system being installed.

Installation Notes

The steel body with zinc-plated finish threads directly into compatible RMC or IMC conduit without special tools. The compact one inch by one inch profile fits tight enclosures, but installers must verify the conduit is threaded and the trade sizes align before assembly.

Questions about this item

What does the .6 inch inside diameter mean when I install this bushing?

The .6 inch inside diameter is the clear opening for conductors after the bushing is threaded into a 3/4 inch female hub, allowing you to pull 1/2 inch conduit or cable through the reduced opening.

How does the NPS thread standard affect what this reducer connects to?

The NPS straight threads mate with matching NPS-threaded rigid metal conduit or IMC fittings, sealing on a gasket or thread compound rather than thread taper.

What physical space do I need to fit the 1 inch overall height and width?

Allow at least 1 inch by 1 inch of clearance around the hub so the hexagonal body can be tightened with a wrench without striking adjacent conduit or enclosures.
