Reducing Bushing 2 in to 1-1/2 in

The RACO 1156 reducing bushing connects 2 inch threaded rigid metal conduit to 1-1/2 inch conduit. It is designed for electricians and installers working with RMC and IMC systems who need a durable transition fitting. The steel construction with zinc plating provides corrosion resistance in standard environments.

Sustained load behavior

The fitting is cULus listed for use with threaded RMC and IMC conduit types. Its steel body maintains structural integrity under continuous mechanical stress and vibration typical in conduit runs. The zinc plated finish protects against oxidation during long-term exposure to moisture or industrial atmospheres.

Installation and common issues

The bushing features NPS threads with a female to male configuration for direct threaded connection. An inside diameter of 1.29 in accommodates the smaller conduit. Installers should verify thread engagement depth and avoid cross-threading during assembly to ensure a secure, code-compliant joint.

Questions about this item

Does the steel zinc-plated RACO 1156 generate any heat or noise when installed in conduit runs?

The RACO 1156 is a passive threaded reducer with no moving parts or electrical components, so it produces no heat or noise during continuous use.

What conduit and threading must already be in place for this 2 in to 1-1/2 in reducer to connect properly?

You need threaded RMC or IMC conduit with 2 in NPS female threads on one side and 1-1/2 in NPS male threads on the other to match the bushing's female-to-male configuration.

Will the 1.29 in inside diameter of this reducer restrict wire pulls when joining existing 1-1/2 in conduit to a 2 in raceway?

The 1.29 in inside diameter matches standard 1-1/2 in trade size conduit, so wire-fill calculations remain unchanged when transitioning between the two conduit sizes.
