Electrical Conduit Reducer

This reducing bushing connects 1-1/4 inch and 3/4 inch IMC or threaded rigid metal conduit in hazardous locations. It provides a female-to-male threaded transition rated for Class I Division 1 and 2, Groups A through D, plus Class II and Class III environments. The aluminum body has a plain finish and suits industrial electrical installations.

Upgrade From Simple Couplings

Use this fitting when a straight coupling cannot bridge different conduit trade sizes in a classified area. The hazardous-location rating replaces standard reducers that lack approval for flammable gases, vapours or combustible dusts. The jump is worth it whenever code requires listed fittings for the specific group and division present.

Threaded Aluminium Installation

The bushing threads directly into female NPT entries and accepts male NPT conduit ends without special tools. Its short 13/16 inch overall length fits tight enclosures but leaves little room for wrench leverage on the smaller 3/4 inch side. Cross-threading the finer aluminium threads is the most common error during assembly.

Questions about this item

What size knockout or hub does the 1-1/4 in MNPT end of this reducing bushing need to fit into?

The male end has a 1-1/4 in NPT thread and requires a matching 1-1/4 in threaded opening or hub.

How do I install this RB125-75A bushing, and what step is commonly missed?

Thread the 3/4 in FNPT end onto the conduit first, then tighten the 1-1/4 in MNPT end into the fitting; the step often missed is applying PTFE tape to the male threads for a hazardous-location seal.

When should this aluminum reducing bushing be replaced in a hazardous-location run?

Replace it if the threads show galling, the 13/16 in body is cracked, or the plain aluminum finish shows corrosion that could compromise the Class I Division 1 rating.
