Appleton RB300-200A IMC Reducing Bushing

This Appleton RB300-200A reducing bushing connects 3 inch and 2 inch trade size IMC threaded conduit in hazardous locations. The aluminum fitting features a 2 inch FNPT female end and a 3 inch MNPT male end with an overall length of 1 1/4 inch. It carries Class I Division 1 and 2, Class II Division 1 and 2, and Class III hazardous location ratings for Groups B, C, D, E, F, G and IIA, IIB + H2.

Verify Conduit Type and Thread Compatibility

Confirm your existing conduit run uses IMC threaded conduit in the 2 inch and 3 inch trade sizes before ordering. The bushing requires female NPT threads on the 2 inch side and male NPT threads on the 3 inch side for proper engagement. Ensure the hazardous location classification of your installation matches the fitting's approved Groups and Divisions.

Suited for Hazardous Area Conduit Transitions

This reducer suits electricians and maintenance teams transitioning between 3 inch and 2 inch IMC conduit in classified areas such as chemical plants, grain facilities or refineries. Installers needing a non-threaded coupling, a different material like steel, or a fitting for non-hazardous dry locations should look at alternative conduit bodies or couplings.

Questions about this item

What fittings come with the RB300-200A reducing bushing and what must be purchased separately?

The bushing is supplied as a single aluminium fitting with 2 in FNPT and 3 in MNPT threads. Compatible IMC or threaded conduit and any locknuts or sealing compounds are not included.

How do I choose between the 2 in and 3 in trade sizes listed for this bushing?

The fitting joins a 3 in male threaded conduit or fitting to a 2 in female threaded opening. Select it when your installation requires that exact step-down transition.

What does the Class I Division 1 rating mean once the bushing is installed in a hazardous location?

It certifies the bushing for use in areas where flammable gases or vapours from Groups B, C, D are present under normal conditions, maintaining conduit system integrity in those zones.
