Reducing Bushing for Hazardous Locations

This Appleton Century Crofts RB100-75A reducing bushing connects conduit of different trade sizes in hazardous environments. It features a 1 in male thread and a 3/4 in female thread, both NPT. The aluminum body carries Class I Division 1 and 2, Class II Division 1 and 2, and Class III ratings for Groups A through G.

Threaded Aluminum Fitting for IMC Systems

The fitting installs directly into threaded rigid metal conduit or intermediate metal conduit runs. Its plain aluminum finish resists corrosion without additional coating. At 3/4 in overall length, it adds minimal bulk to the conduit assembly while maintaining the required hazardous-location seal.

For Electricians Running IMC in Classified Areas

This bushing suits installers who need to step down from 1 in to 3/4 in conduit within a single hazardous-rated enclosure. It does not serve applications requiring non-threaded couplings, PVC conduit compatibility, or larger trade-size reductions.

Questions about this item

How far does the 1 in MNPT thread engage before bottoming out?

The overall length is 3/4 in so the male thread engagement is limited to that depth.

Does the aluminium body get hot when used continuously in a Class I Division 1 location?

The fitting is passive aluminium with no current-carrying parts; it does not generate heat during operation.

What conduit and thread sealant are required to complete a hazardous-location installation?

You need IMC or threaded RMC in 3/4 in and 1 in trade sizes plus a listed thread sealant for the FNPT/MNPT joints.
