Bridgeport Fittings 1179 Steel Reducing Bushing, 3" to 2-1/2" Threaded Fitting

Bridgeport Fittings delivers professional-grade conduit hardware for electrical contractors, and this steel reducing bushing is engineered to transition rigid or IMC conduit runs from a 3" trade size down to 2-1/2" without requiring a complete fitting change-out. Manufactured from solid threaded steel, the bushing threads directly into a larger hub, box, or enclosure opening to accept smaller-diameter conduit while preserving a secure mechanical and electrical connection point. This reducing bushing helps installers adapt existing conduit runs, panelboards, and enclosures to accommodate a smaller conduit size, simplifying transitions in commercial and industrial electrical systems where mismatched trade sizes are common. Its solid steel-threaded body is built to hold up under the torque and stress of routine conduit installation and service work.

Key Features

  • Trade Size Reduction: Steps conduit runs down from a 3" trade size to 2-1/2", allowing a single fitting to bridge mismatched conduit sizes.
  • Durable Steel Construction: Solid steel body stands up to impact, torque, and mechanical stress encountered during installation and long-term service.
  • Threaded Connection: Steel threaded design allows the bushing to engage directly into a hub, box, or enclosure opening for a secure, code-compliant fit.
  • Space-Saving Transition: Eliminates the need for bulky couplings or multiple adapters when stepping down between conduit trade sizes.
  • Dependable Continuity: Metal-to-metal threaded contact supports a stable, low-resistance connection point across the conduit system.
  • Red Color-Coding: Finished in red for quick visual identification on the job site or in inventory bins.
  • Field-Ready Design: Simple hand-tightened, threaded installation speeds up conduit size transitions without special tools.

Bridgeport Fittings BPF1179 – Frequently Asked Questions

1) What size conduit does the Bridgeport 1179 reducing bushing step down to?
The Bridgeport Fittings 1179 takes a 3 inch trade size opening down to 2-1/2 inch conduit. It threads into the larger 3 inch hub, box, or enclosure opening and accepts the smaller 2-1/2 inch conduit, so one fitting bridges the mismatch instead of swapping out the whole hub.
2) Can I use a reducing bushing on rigid and IMC conduit?
Yes. The 1179 steel bushing is made for rigid and IMC trade size transitions, since both use threaded conduit ends that engage the bushing's threads. It is not a fitting for EMT, which is not threaded in the field.
3) Is this reducing bushing suitable for a panelboard hub that was drilled for 3 inch conduit?
That is one of its main uses. The 1179 reduces panelboard, box, and enclosure hubs from 3 inch to 2-1/2 inch, which is common on retrofits where the existing opening is oversized for the new feeder.
4) Is the Bridgeport 1179 bushing steel or die-cast zinc?
Steel. The 1179 has a solid steel threaded body, which is what you want for rigid and IMC work where the fitting sees wrench torque and impact during installation and later service.
5) Do I need a coupling and an adapter, or will one bushing handle the size change?
One fitting does it. The 1179 threads straight into the 3 inch opening and receives 2-1/2 inch conduit, which avoids stacking a coupling plus adapters and keeps the transition tight to the enclosure where space is short.
6) Will a threaded reducing bushing keep ground continuity through the conduit run?
Metal-to-metal threaded contact is the point of the steel design: the bushing makes a mechanical and electrical connection between the 3 inch hub and the 2-1/2 inch conduit, supporting a low-resistance connection point across the raceway. Tighten it properly, as with any threaded metallic fitting, for that contact to do its job.
7) What is the Bridgeport part number to order for a 3 inch to 2-1/2 inch steel reducing bushing?
Bridgeport Fittings part number 1179. It is a single configuration, listed at the 3 inch trade size, so there is no finish or material option to pick.
8) Why is this reducing bushing red, and does the color mean anything electrically?
The red finish on the 1179 is for identification only, so crews can pick the right trade size out of a bin or a pouch quickly. It does not indicate a different rating or material; the body underneath is steel.
