Hubbell Incorporated RACO 1150 IMC Reducing Bushing 1-1/2 in to 1 in Steel Zinc Plated Gray

Electrical Reducing Bushing 1150

The Hubbell RACO 1150 is a threaded steel reducing bushing designed to connect intermediate metal conduit of different trade sizes. It adapts a 1-1/2 inch female threaded opening down to a 1 inch male thread for conduit transitions. This component suits electricians and maintenance crews joining rigid metal conduit or IMC runs in commercial and industrial installations.

Zinc Plated Steel Construction

The bushing body is steel with a zinc plated gray finish that resists corrosion in damp or outdoor locations. NPS threads on both ends provide a secure mechanical connection without the need for additional thread sealant in dry locations. At 23/32 inch overall length and 1 7/8 inch width, the fitting adds minimal bulk inside junction boxes or enclosures while meeting cULus listing requirements for safety compliance.

Conduit Size Transition Solution

This reducer replaces improvised couplings or oversized fittings when stepping down from 1-1/2 inch to 1 inch trade size conduit. The 1.04 inch inside diameter maintains wire fill capacity through the transition point. The jump is worth it when a raceway system changes conduit size due to wire count reduction or space constraints, eliminating the need to pull conductors through an oversized raceway section.
