Frequently Asked Questions

What is a RACO reducing bushing used for?

A RACO reducing bushing is used to transition from a larger trade size of threaded rigid metal conduit (RMC) or intermediate metal conduit (IMC) to a smaller size. This specific model reduces from 1-1/4 in to 1/2 in, allowing connection of different conduit diameters in electrical installations.

What are the specifications of the RACO reducing bushing 1145?

The RACO reducing bushing MPN 1145 is made of zinc-plated steel with a gray finish. It has a reduction size of 1-1/4 in to 1/2 in, an overall length of 11/16 in, and a threaded NPS connection with female-to-male thread gender. It is cULus Listed and compatible with threaded RMC and IMC conduit.

Where to buy RACO reducing bushings worldwide?

RACO reducing bushings are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this cULus Listed fitting.

How to install a RACO reducing bushing?

To install a RACO reducing bushing, thread the male end into the larger conduit hub or fitting, then thread the smaller conduit into the female end. Use a wrench to tighten securely without over-torquing. Ensure threads are clean and apply a suitable thread compound for metal conduit to maintain a reliable ground path.

Used in

Common applications for RACO
Industrial machinery — RACO liquid-tight connectors (e.g., 3520-3, 3414) terminate flexible metallic conduit at motor and control enclosures.
Water and wastewater treatment — RACO 90-degree liquid-tight connectors (e.g., 3430) route conduit in washdown and outdoor areas requiring liquid-tight terminations.
Commercial electrical raceways — RACO short elbows (e.g., 1/2 in and 3/4 in iron elbows) change direction in IMC and RMC runs per UL 514B.
Panel and equipment wiring — RACO flex screw-in couplings (e.g., 2272) join sections of 1/2 in flexible conduit between machines and junction points.
Raceway transitions — RACO flex-to-EMT couplings (e.g., 1482, 1483) connect flexible conduit to EMT in mixed raceway installations.
Maintenance and repair — RACO conduit fittings and boxes are stocked as spares for replacing damaged terminations and couplings in existing raceways.
